Question

Ammonium perchlorate NH4ClO4 is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N2 gas, chlorine Cl2 gas, oxygen O2 gas and water vapor, releasing a great deal of energy. Calculate the moles of ammonium perchlorate needed to produce 0.070mol of nitrogen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

Answer:

hey

Explanation:

see your ans above

hope it helps

Answer 2

Answer:

Solution: The balanced equation: 2 NH4ClO4 → N2 + Cl2 + 2 O2 + 4 H2O So: 2 mol of NH4ClO4 produces 4 mol of water X mol of NH4ClO4 produces 1.9 mol of water Solving the proportion: X = (1.9 ∙ 2) / 4 = 0.95 mol
