Question

Ammonium perchlorate (NH4CIO4) is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen (N₂) gas, chlorine (C1₂) gas, oxygen (O₂) gas and water vapor, releasing a great deal of energy. Calculate the moles of water produced by the reaction of 0.065 mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.10100 0.0X S?FEEDolo84

Answer 1

1) Balance the chemical equation.

`NH_4ClO_4\rightarrow N_2+Cl_2+2O_2+4H_2O`

2) Convert moles of NH4CIO4 to moles of H2O produced.

The molar ratio between NH4CIO4 and H2O is 1 mol NH4CIO4: 4 mol H2O.

`mol\text{ }H_2O=0.065\text{ }mol\text{ }NH_4ClO_4*\frac{4\text{ }mol\text{ }H_2O}{1\text{ }mol\text{ }NHClO_4}=0.26\text{ }mol\text{ }H_2O`

The moles of H2O produced in the reaction are 0.26 mol H2O.
