Ammonium perchlorate is the solid rocket fuel used by the U. S. Space Shuttle. It reacts with itself to produce nitrogen gas , chlorine gas , oxygen gas , water , and a great deal of energy. What mass of water is produced by the reaction of 9.6 g of ammonium perchlorate

2.94 g of water are produced by this decomposition

Explanation:

We need to determine the reaction to solve this problem:

The reactant is the ammonium perchlorate

The products are N₂, Cl₂, O₂ and H₂O

The reaction is: 2NH₄ClO₄ →  N₂ + Cl₂ + 2O₂ + 4H₂O

We convert the mass of the reactant to moles:

9.6 g . 1 mol / 117.45 g = 0.0817 moles

Ratio is 2:4. Let's make a rule of three:

2 moles of perchlorate produce 4 moles of water.

Then, 0.0817 moles of perchlorate will produce (0.0817 . 4)/2 = 0.163 moles

We convert the moles of produced water, to mass (g)

0.613 mol . 18 g / 1mol = 2.94 g
