Question

Ammonium perchlorate is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen gas, chlorine gas, oxygen gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce of water. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answer 1

Answer:

0.95 mol NH₄ClO₄

Explanation:

There is some info missing. I think this is the original question.

Ammonium perchlorate is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen gas, chlorine gas, oxygen gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce 1.9 mol of water. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Let's consider the following balanced equation.

2 NH₄ClO₄ → N₂ + Cl₂ + 2 O₂ + 4 H₂O

The molar ratio of NH₄ClO₄ to H₂O is 2:4. The moles of NH₄ClO₄ required to produce 1.9 moles of H₂O are:

1.9 mol H₂O × (2 mol NH₄ClO₄/ 4 mol H₂O) = 0.95 mol NH₄ClO₄
