ammonium nitrate decomposition reaction equation

Ammonium nitrate itself does not burn, but in contact with other combustible materials it increases fire hazard and supports fire even in the absence of O2. decomposition reactions of FGAN can only be assumed. More powerful, or simply easier to detonate, or both? Record your observations on these data pages as you perform each reaction. The sulfides of Group IA, ammonium, calcium, and barium are soluble. Mixtures of superphosphates and organic materials may ignite bulk quantities of ammonium nitrate if the internal temperature exceeds 90C. Regardless, $\ce{NH4NO3}$ is not considered a flammable or combustible material at ambient temperature and pressure (Ref.1). You dont have sufficient information to answer this question. As this is nitrogens lowest known oxidation state, it cannot act as an oxidising agent but it can act as a reducing agent see for example the Ostwald process in which ammonia (also in the $\mathrm{-III}$ oxidation state) is burned in an oxygen atmosphere ultimately leading to nitric acid. Lets look at two other cases in which we have too little or too much ammonium nitratefor the amount of fuel oil that has been added. Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. Fused ammonium nitrate mixed with powdered metals such as zinc, copper, lead, and aluminum can lead to a violent and sometimes explosive reaction. ________>________>________>________>________, most active (most easily oxidized) to least active. Therefore, the number that you need to give to your blaster is 0.42 lb. A second method for phosphorus immobilization is precipitation. It is important to achieve an oxygen balance within the explosive. However, if it is contaminated with impurities, the risk of it detonating increases. FGAN 2NH 4 NO 3 2N 2 + 4H 2 O + O 2. Please send comments or suggestions on accessibility to the site editor. If youre looking to help the huge numbers of people affected by the explosion in Beirut, the Lebanese Red Cross is accepting donations, and Impact Lebanon are raising disaster relief funds. If no discernable initial change is noted, let the reaction mixture stand for at least five to ten minutes before observing again. As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. Nitrates and nitrites are used to cure meats and to develop the characteristic flavor and pink color, to prevent rancidity, and to prevent growth of Clostridium botulinum spores in or on meats. Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. Displacement Reactions (also called Single Replacement Reactions) involve the displacement of one element in a compound by another element. During this time, a layer of very hot, en.wikipedia.org/wiki/Ammonium_nitrate_disasters, en.wikipedia.org/wiki/Texas_City_disaster, https://en.wikipedia.org/wiki/2020_Beirut_explosions, https://doi.org/10.1016/j.jhazmat.2005.03.028, https://doi.org/10.1016/j.jece.2017.12.003, US CSB West Fertilizer Explosion final report, reportedly there were fireworks stored in the same warehouse. Fuel is added because it has surplus oxygen. 2217 Earth and Engineering Sciences Building, University Park, Pennsylvania 16802 This reaction takes place at a temperature of over 300C. Possible sources of contamination in an (possibly including molten asphalt and plastic dripping from the burning composite shingle roof and PVC An explosion goes straight to N2 and O2. Write a balanced equation for this reaction. detonation. Still the other answers are valid and more detailed from a chemical mechanicist viewpoint. If no reaction occurs write the words "no reaction" (or NR) instead of the products in your balanced equation and indicate why your think there was no reaction. Obviously, nitrate leaching represents a loss of available nitrogen from the plant-soil system. Wszystko, co powiniene o nich wiedzie. Are there conventions to indicate a new item in a list? and exothermic decomposition reactions that take place with increasing temperature. For example, hydrogen and oxygen gases combine to give water: Decomposition Reactions occur when a compound breaks apart to yield two or more new substances. This paper 1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu {230-260 ^\circ C}$. This structure provides extensive surface area both external to the particle and internal between the plates. Referred to as nonoccluded phosphorus, the phosphate ion is bound to the surface of SiO2 or CaCO3. Fractured crystalline edges expose oxygen and hydroxyl groups that present a net negative charge. In its pure form, ammonium nitrate isnt usually explosive in fact, its safe to handle. decomposition reactions beyond the first step have yet to be uniquely defined, and subsequent From most active (most easily oxidized) to least active: Now use the above results to write products for the reactions below. One point out the presence of NO2 clearly seen by its red brownish colour before the second powerful explosion. explosion, Rae said. Temperatures and Reaction Rate By George Feick and R. M. Hainer, Reaction Rates of Ammonium Nitrate in Detonation Balancing Strategies: In this decomposition reaction, NH4NO3 is breaking apart (decomposing) into N2 + O2 + H2O. Ammonium nitrate prills can be produced in either high- or low-density form, depending on the concentration of the melt. [16] Find another reaction. Fertilizer value is derived both from the high total nitrogen content (33%) split between fast acting nitrate nitrogen and the slower acting ammonium nitrogen, plus the ease of marketing and handling a solid product. Do not put the metal pieces in the sink. Thus, for the first case with a 92:8 ratio, we have: And for the second case, with a 96.6 : 3.4 ratio, we have: Lets look at the right-hand side of the equations. It decomposes at 230oC producing nitrous oxide gas (N 2 O) and water vapour. 2023 | Powered by w3.css | Formation of a precipitatenoted as the formation of a cloudy solution, formation of a gel, or. Clays are composed of plate-like crystalline units that are laminated to form individual particles. It decomposes at 230oC producing nitrous oxide gas (N 2 O) and water vapour. But at the detonation temperature, $\mathrm{t_d}$ (the temperature at which compounds detonate), ammonium nitrate fully decomposes to nitrogen, oxygen and water releasing a tremendous amount of energy. 1 0 obj NH 4 NO 3 (s) N 2 O(g) + 2H 2 O(g) Above 260oC, if confined and when contaminated, ammonium nitrate will explode forming toxic Nitrate has a negative charge and will remain in the soil solution. In each case one of the products results by combining two ions that are removed from the solution by the reaction. Chemical reactions are often accompanied by observable changes as they occur. The nitric acid is titrated with a standardized sodium hydroxide solution to a phenolphthalein endpoint or a pH endpoint. decomposition reactions become increasingly more complex. Another possible detonation scenario focuses on the elevator pit near the FGAN bin. The site editor may also be contacted with questions or comments about this course. Still $\ce{NH4^+}$ reduces $\ce{NO3^-}$ good enough, by itself. Well choose a 92: 8 ratio for the first case and a 96.6: 3.4 ratio for the second case Ive picked these ratios so that we have an integer number of moles in our formula. Dalsze korzystanie ze strony oznacza, e zgadzasz si na ich uycie. Method 1 determines the percentage of ammonium nitrate by reacting formaldehyde with ammonium nitrate, which produces nitric acid. Part of my motive for asking is the news today (Aug 4, 2020) of an explosion in Beirut. This is an important consideration because wastewater could have a significant quantity of monovalent cations such as sodium from salt and water softeners. However, they are capable of reacting and they have thermodynamically favourable reaction pathways as Matthews answer nicely outlines. 2H 2(g) + O 2(g) 2H 2O(l) Decomposition Reactions occur when a compound breaks apart to yield two or more new substances. Thermodynamic properties of substances. NH4NO3 - > 2H2O + N2O, However a passing shockwave can induce this decomposition in a large quantity of ammonium nitrate at once, which is a detonation. Although you know the weight of each ingredient in the mix, you dont know the density of the mix. Also, most products are gases. High-density prills, granules, and crystals are used as fertilizer, while ammonium nitrate grains are used solely in explosives, and low-density prills that are small aggregates or globules of the materialmost often a dry sphereformed from a melted liquid. But with rapid heating or detonation, a The Pennsylvania State University 2020, Module 1: Introduction to the Mining Industry, Module 2: The Life Cycle of a Mine and Related Matters, 6.2.1: Mixing ANFO and the Oxygen Balance, 6.2.3: Classification of Common Industrial Explosives, 6.2.5: Key Properties Affecting Choice of Explosives, Department of Energy and Mineral Engineering, Department of Materials Science and Engineering, Department of Meteorology and Atmospheric Science, Earth and Environmental Systems Institute, Earth and Mineral SciencesEnergy Institute, iMPS in Renewable Energy and Sustainability Policy Program Office, BA in Energy and Sustainability Policy Program Office, 2217 Earth and Engineering Sciences Building, University Park, Pennsylvania 16802. poor quality control at the batch mixing truck; incorrect formulation, for example by adding a sensitizer like aluminum, but not accounting for it in the addition of the fuel oil; improper timing of adjacent holes, allowing the explosive to become unconfined by the time it detonates; explosives at the collar of the hole (increases fume production, not fragmentation). J.R. Buchanan, in Comprehensive Water Quality and Purification, 2014. The cloud consisted of powerful oxidizers that would be How does potassium nitrate work as an oxidiser? Overall agronomic experiments show only small differences in crop utilization of N from urea compared with nitrate-containing fertilizers. NH 4 NO 3: molecular weight = 80.05 g/mol CH 2: molecular weight = 14.03 g/mol The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. WebN = 14.006 H = 1.0078 N = 14.006 C = 12.009 And then, we can calculate the molecular weight of the ammonium nitrate and the fuel oil. You should verify this result. NH 4 NO 3 (s) N 2 O(g) + 2H 2 O(g) Above 260oC, if confined and when contaminated, ammonium nitrate will explode forming toxic The strength of the bond that holds clay particles together is a function of the distance between the particles and valence of the ions. High concentrations of nitrate in surface waters can lead to eutrophication (the sudden enrichment of natural waters with excess nutrients which can lead to the development of algal blooms and other vegetation). Webat ~23% ammonium nitrate decomposition; and at 230oC at 14%. Wastewater containing ammonia and nitric acid must be neutralized to produce ammonium nitrate. Heating also poses a danger: ammonium nitrate decomposes at around 230C, and can explode when heated to between 260300C if its confined. The sulfates of lead(II), barium, and calcium are insoluble. In addition, the added mass of the derivative moves the molecular ion from m/z = 17/18 for NH3+ and NH4+ to m/z = 74, 62 and 44 for the parent ion and fragments of the butyl chloroformate-derivatized ammonia.18 This moves the molecular ion away from interference from water that would produce peaks due to OH+ at m/z = 17 and H2O+ at m/z = 18. The gas, NO, changes to NO2 when exposed to the atmosphere. These transformations can be studied by labeling the N in urea or either the ammonium or nitrate parts of ammonium nitrate with 15N, the heavy isotope of nitrogen. <> Examples are shown in Figures 5-7. Plus, ammonium nitrate's melting point is ~337 F, meaning it can become molten, possibly escaping its container, and readily mixing with fuel sources. Be sure to mix the solutions well. By continuing you agree to the use of cookies. Chlorides, Bromides and Iodides are soluble. In this review data from the literature on thermal decomposition of ammonium nitrate (AN) and the effect of additives to their thermal decomposition are summarized. For example, liquid ammonium nitrate may be sold as a fertilizer, generally in combination with urea or the liquid ammonium nitrate may be concentrated to form an ammonium nitrate melt for use in solids formation processes. Task 2 Decomposition or explosion? ScienceDirect is a registered trademark of Elsevier B.V. ScienceDirect is a registered trademark of Elsevier B.V.

The mass of the falling FGAN, combined with the strong confinement of the Products are sometimes coated with clays or diatomaceous earth to prevent agglomeration during storage and shipment, although additives may eliminate the need for coatings. rev2023.3.1.43269. Absorption of heatnoted as a temperature decrease. WebNH 4 NO 3 N 2 + O 2 + H 2 O. 1 M ammonium nitrate and 6 M sodium hydroxide. Web1. The US CSB West Fertilizer Explosion final report, section 4.3, outlines three possible scenarios under which the 2013 explosion in West, Texas could have occurred. Its simplicity of production and low cost, about $170/tonne in the U.S. in 1995, add to its product appeal. If nitrate is a concern then, effluent application should be limited to the agronomic requirement of the plants in the soil absorption area, and then a large fraction of the plant biomass should be removed each year to prevent the organic nitrogen from being mineralized upon plant decomposition.

Recall that a more active metal displaces a less active metal, a more active metal to is needed to displace hydrogen from water than to displace it from an acid, and that a metal that displaces hydrogen from acid is ranked as more active than hydrogen. The decomposition of an oxygen-balanced ANFO is: We can find the atomic weights for each of the elements from the periodic table. The starting shockwave could have come from another explosive or from a fuel fire that was intensified by the oxidizing properties of ammonium nitrate. $$\ce{8NH4NO3 -> 5N2 + 4NO + 2NO2 + 16H2O } \quad \Delta H = \pu{-600 kJ/mol} \tag7$$. Decomposition, pitting, or the disappearance of a solid metal. This fire further accelerated the reaction, further heating the remaining ammonium nitrate to the point of detonation and that's when ammonium nitrate exploded instantaneously releasing tremendous amount of energy which send shockwaves around the site along with a white mushroom shaped cloud (from @DDuck's comment) which could probably be nitrogen and/or water vapours where the humid air (water vapor laden air) condensed due to the explosion(@StianYttervik) with release of nitrogen. When nitrate is leached, it must be accompanied by an equivalent amount of cations to maintain charge balance. At temperatures below around 300 C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 N 2 O + 2H 2 O. The common cations adsorbed by clay surfaces are H+, Al3+, Ca2+, Mg2+, K+, and Na+. When one thinks of fire and dissects the requirements of a fire into a fuel and an oxidiser, this is in chemical terms only a different way of determining an oxidising agent and a reducing agent in a redox reaction. The main point of this answer is to use the 2013 West Fertilizer Company explosion (USCSB animation for context) as an example of scenarios that could lead to AN detonation, and also to show that the situation can become very complex and unpredictable. This scenario involved heating of the FGAN through the walls and is noted as being highly unlikely, so to keep this short I'm not going to quote it here. Are these explosions also detonations? We use cookies to help provide and enhance our service and tailor content and ads. [ Check the balance ] The thermal decomposition of ammonium nitrate to produce nitrogen, water and oxygen. the surface of the FGAN pile. Steady-state Reaction So, now we know that when we mix the ammonium nitrate with the fuel oil, we need to do it in this proportion if we want an oxygen balanced reaction. Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. | Socratic. When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. During the fire, soot from the smoke and also collapsing wood What is ammonium nitrate, why can it explode, and what happens when it does? the FGAN pile in the main bin and possibly in an adjoining bin linked to the main bin through a series of and oxygen gas and water vapor. You explained the contamination part, Jan explained the instability of AN. 3 0 obj Place a small amount (an amount that will fit on the end of a spatula) of solid copper(II) sulfate pentahydrate in a medium test tube. Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. Interestingly, ammonium nitrite ($\ce{NH4NO2}$) is far more labile and very hard to prepare as the two ions tend to react to form nitrogen gas and water even in solution at room temperature. Some of the gas-forming reactions may also be classified as neutralization reactions. How can I recognize one? With a greater surface area, the chemical activity is greater for fine-textured soils. The ammonium N is typically nitrified to nitrate over a period of 14weeks. The best answers are voted up and rise to the top, Not the answer you're looking for? The solubility of the substances. Cautiously feel the outside of the test tube. And from section 4.3, a few detonation scenarios: Based on the location of the pile and the properties of the bin along with the circumstances of other fire induced incidents, one possible scenario is that a period of contamination with soot and other organics Why is there a memory leak in this C++ program and how to solve it, given the constraints (using malloc and free for objects containing std::string)? They also further noted that beyond $\pu{280 ^\circ C}$, $\ce{NH4NO3}$ is capable of rapid, self-accelerating decomposition (to the point of detonation). bin, spilling FGAN into a mixture of burning rubber from the melted elevator belt and residual FGAN in The products of the reaction are Examining ammonium nitrate reveals that there is another nitrogen atom in the ammonium cation which is in the $\mathrm{-III}$ oxidation state. salts, carbons, acids, fibers, and sulfides. Emissions from ammonia and nitric acid occur primarily when they form solutions (neutralizers and concentrators), and when they are used in granulators. Plants producing nitric acid and ammonium nitrate produce wastewaters containing these compounds and ammonia. Seed materials, zinc, and other Be sure to include the states of all compounds in your equations (solid, liquid, aqueous, or gas). harmless -- they're found in our atmosphere -- but the process It's hard to imagine something worse than the explosion I saw in videos, but I wonder what the difference would have been if it were combined with fuel oil? The additional ventilation caused a marked decrease in dark smoke and probably was accompanied by a Ta strona korzysta z ciasteczek aby wiadczy usugi na najwyszym poziomie. Things like that did happen before. In Europe ammonium nitrate or calcium ammonium nitrate (CAN) is widely used. contaminated, and sensitive liquid FGAN could have built up on the pile. In other words, they will fill the cup with their batch of mixed ANFO and weigh it. drop pipe from the elevator mechanism) was followed by about 5 to 6 minutes of intense radiant heating Give a balanced equation for the decomposition reaction. the burning wood and other fuels. Like ammonium, nitrate has many competing fates in the soil ecosystem (Fig. $$\ce{NH4NO3 -> 3/4N2 + 1/2NO2 + 2H2O } \quad \Delta H = \pu{-944 kJ/mol} \tag5$$. This reaction occurs as the match ignites, causing the match head to be surrounded by an oxygen atmosphere. NH 4 NO 3: molecular weight = 80.05 g/mol CH 2: molecular weight = 14.03 g/mol The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. You'll need to be patient balancing this equation! Task 2 Decomposition or explosion? But the straight answer to your question is that the oxidizer and the reducing stuffs are already within the salt. WebThermal decomposition of ammonium nitrate occurs >200 C. Can the Spiritual Weapon spell be used as cover? WebAmmonium nitrate | NH4NO3 or H4N2O3 | CID 22985 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. S.B. I thought ammonium nitrate was an oxidizer that needed to be mixed with fuel to form a high explosive (e.g., ANFO). document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 2015-2022 Gametip.pl | Polityka Prywatnoci | Wsppraca. This is a requirement the equation must satisfy to be consistent with the law of conservation of matter. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. A number of additives are available commercially that retard either urea hydrolysis or nitrification, so retaining a greater proportion of N from fertilizer in the ammonium form and decreasing the amount as nitrate. Remove the tube from the flame and quickly and cautiously note the smell.

The force of the ammonium nitrate explosion is provided by the rapid generation of gas as it breaks down. To write balanced equations for the reactions studied. Write a balanced equation for this reaction. Note: Method 1 is of less importance now and used less because formaldehyde can be a safety hazard if not used properly. In Beirut we saw that there was already a fire burning for a significant amount of time before the explosion, as well as a smaller explosion that occurred < 30 seconds before the main one. For example, in the first reaction given above, elemental lead is oxidized to lead(II) and copper is reduced from copper(II) to elemental copper. @MuhammadAbbass As many of the answers state, ammonium nitrate is both an oxidiser. Exchange Reactions (also called Double Replacement or Metathesis Reactions) occur when two compounds that form ions in solution react by switching ion partners. Thus, soils are also depleted of cations when nitrate is leached. used up and exploded. AN can melt and the liquid can do unpredictable things. This interest has been stimulated by the demand for ammonium nitrate as a fertilizer component and as an ingredient in explosives. This paper1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu{230-260 ^\circ C}$. Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. Thus, these reactions have the general form: One of three conditions must be met for these reactions to occur: (1) the formation of an insoluble ionic compound, observed as a precipitate, (2) the formation of a gas, or (3) the production of water from hydroxide and hydrogen ions (an example of an acid-base neutralization). holes cut in the partition between the bins. D.S. Matter undergoes three kinds of change: physical, chemical, and nuclear. The oxygen is consumed by the fuel oil or a readily oxidizable metal such as aluminum or magnesium present to contribute further heat and power to the detonation process. At higher temperatures (i.e., between $\pu{170 ^\circ C}$ and $\pu{280 ^\circ C}$) exothermic irreversible reactions (equations $(3)-(5)$) occur: $$\ce{NH4NO3 -> N2O + 2H2O } \quad \Delta H = \pu{-59 kJ/mol} \tag3$$ Nitrate that leaches eventually enters ground and surface waters, where it may have potentially adverse environmental effects. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Soil chemistry is the interaction between soil solution and solid phase. A small-scale but important use of ammonium nitrate is for the preparation of inhalation grade nitrous oxide for use as an anaesthetic. Why did the Soviets not shoot down US spy satellites during the Cold War? The leaching of basic cations, such as K+ and Ca2+, reduces the base saturation of a soil and increases exchangeable acidity. If needed, crops with high nitrate uptake can be planted and harvested to maintain an appropriate nutrient balance. What are the other chemical substances that are formed in the process of making ammonium nitrite? Approximately 15%20% (v/v) of the ammonium nitrate prepared in this manner is used for explosives and the balance for fertilizer. Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, We've added a "Necessary cookies only" option to the cookie consent popup. One reason that ammonium nitrate is so explosive is that it contains in the same molecule both a fuel, in the form of the ammonium ion, and a strong oxygen- producing agent, nitrate. We can calculate the density of ANFO mixed to this ratio. Melvin A. Cook, Earle B. Mayfield, and William S.
