Answer:
2.9 g of water are produced by 9.6 g of ammonium perchlorate
Note: The question is incomplete. The complete question is given below:
Ammonium perchlorate (NH₄ClO₄) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) , and a great deal of energy. What mass of water is produced by the reaction of 9.6 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.
Step-by-step explanation:
The reaction of ammonium perchlorate (NH₄ClO₄) to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) is shown in the balanced chemical equation given below:
2 NH₄ClO₄ → N₂ + Cl₂ + 2 O₂ + 4 H₂O
From the equation, 2 moles of ammonium perchlorate produces 4 moles of water, i.e. mole ratio of NH₄ClO₄ to H₂O = 2 : 4 = 1 : 2
molar mass of ammonium perchlorate, NH₄ClO₄ = (14 + 4 * 1 + 35.5 +16 * 4) = 117.5
molar mass of water, H₂O = (2 * 1 + 16) = 18.0 g
mass of water produced = moles of ammonium perchlorate * 2 * molar mass of water
moles of perchlorate = mass / molar mass = 9.6/117.5
mass of water produced = 9.6/117.5 * 2 * 18.0 g = 2.94 g of water
Therefore, 2.9 g of water are produced by 9.6 g of ammonium perchlorate
