Ammonium nitrate has been used as a high explosive because it is very unstable and decomposes into several gaseous substances. The heat from the decomposition reaction results in the rapid expansion of these gases (which include nitrogen, oxygen, and water) and produces the explosive force. Write the balanced chemical equation for this reaction:



Calculate the mass of each gas that is produced if 125 grams of ammonium nitrate decomposes completely.

Step 1: Convert 125 g of ammonium nitrate to moles.



Step 2: Using the balanced equation, determine the number of moles of each gas that will be produced.


Nitrogen:


Oxygen:



Water:


Step 3: Convert from moles back to grams.


Nitrogen:


Oxygen:



Water:

Terrorists often use ammonium nitrate fertilizer as aningredient in car bombs. When ammonium nitrate explodes, itdecomposes to gaseous nitrogen, oxygen, and water vapor. The forceof the explosion results from the sudden production of a hugevolume of hot gas.
(a) Write a balanced equation for the reaction.
(b) What volume of gar (in liters) is produced from the explosionof 1.80m^3 of solid ammonium nitrate? Assume that the gas has atemp of 500°C and a pressure of 1.00 atm. The density of ammoniumnitrate is 1.725 g/cm^3,

(c) Use the thermodynamic data in Appendix B to calculate theamount of heat (in kilojoules) released in the reaction.

The effectiveness of nitrogen fertilizers depends on both their ability to deliver nitrogen to plants and the amount of nitrogen they can deliver. Four common nitrogen-containing fertilizers are ammonia, ammonium nitrate, ammonium sulfate, and urea [(NH2) 2CO)]. Rank these fertilizers in terms of the mass percentage nitrogen they contain. Rank fertilizers from largest to smallest mass percentage nitrogen they contain. Some of them may be equivalent.

Many nitrate salts can be decomposed by heating. For example, blue, anhydrous copper(II) nitrate produces the gases nitrogen dioxide and oxygen when heated. In the laboratory, you find that a sample of this salt produced a 0.195-g mixture of gaseous NO2 and O2 with a total pressure of 725 mm Hg at 35 °C in a 125-mL flask (and black, solid CuO was left as a residue). What is the average molar mass of the gas mixture? What are the mole fractions of NO2 and O2 in the mixture? What amount of each gas is in the mixture? Do these amounts reflect the relative amounts of NO2 and O2 expected based on the balanced equation? Is it possible that the fact that some NO2 molecules combine to give N2O4 plays a role?

Heating copper(II) nitrate produces nitrogen dioxide and oxygen gas and leaves a residue of copper(II) oxide.
