If ONE mole of rocket fuel, ammonium perchlorate, NH4ClO4, is allowed to react with excess Al so that all of the NH4ClO4 is consumed, how many molecules of water will be produced? (All reactants & products are present in a 1:1 ratio.)

Sagot :

Answer:

9.03×10²³ molecules of H₂O

Explanation:

To solve this, we need to propose the reaction

NH₄ClO₄  →  ammonium perchlorate

Al → Aluminum

Those are the reactants; the reaction is:

6NH₄ClO₄  +  10Al →  5Al₂O₃ + 3N₂ + 6HCl + 9H₂O

Then, water is one of the products. If we see the reaction, is a redox type.

Ratio is 6:9. In conclussion:

6 moles of ammonium perchlorate can produce 9 moles of H₂O

Then 1 mol of salt, may produce (1 . 9)/6 = 1.5 moles of water

Let's count the molecules:

1.5 mol . 6.02×10²³ molecules /mol = 9.03×10²³ molecules of H₂O
