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 chlorine produced by the reaction of of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answer 1

The question is incomplete , complete question is :

Ammonium perchlorate $NH_4ClO_4$ 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 chlorine produced by the reaction of 2.5 mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

Answer:

1.2 moles of chlorine produced by the reaction 2.5 moles of ammonium perchlorate.

Explanation:

$2NH_4ClO_4(s)\rightarrow N_2(g)+Cl_2(g)+2O_2(g)+4H_2O(g)$

Moles of ammonium perchlorate = 2.5 moles

According to reaction, 2 moles of ammonium perchlorate on decomposition gives 1 mole of chlorine gas, then 2.5 moles of ammonium perchlorate wil give:

$\frac{1}{2}\times 2.5 mol=1.25 mol\approx 1.2$ of chlorine gas

1.2 moles of chlorine produced by the reaction 2.5 moles of ammonium perchlorate.
