The question is incomplete , complete question is :
Ammonium perchlorate [tex]NH_4ClO_4[/tex] 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:
[tex]2NH_4ClO_4(s)\rightarrow N_2(g)+Cl_2(g)+2O_2(g)+4H_2O(g)[/tex]
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:
[tex]\frac{1}{2}\times 2.5 mol=1.25 mol\approx 1.2[/tex] of chlorine gas
1.2 moles of chlorine produced by the reaction 2.5 moles of ammonium perchlorate.
