Chapter 11, Problem 98A

Ammonium sulfide reacts With copper(ll) nitrate in a double replacement reaction. What mole ratio would you use to determine the moles of ${\text{NH}}_{\text{4}}{\text{NO}}_{\text{3}}$ produced if the moles of $\text{CuS}$ are known?

Interpretation Introduction

Interpretation:

The mole ratio should be used to determine number of moles of ammonium nitrate formed.

Concept introduction:

Mole ratio is the ratio of number of moles of reactants to number of moles of product.

Answer to Problem 98A

The ratio of number of moles of ammonium nitrate can be used determine the number of moles of copper sulfide because it is given that number of moles of CuS are known.

Explanation of Solution

$(NH4)2S+Cu(NO3)2\to 2NH4NO3+CuS$

It is a double displacement reaction.

Thus, the ratio of number of moles of ammonium nitrate can be used determine the number of moles of copper sulfide because it is given that number of moles of CuS are known.
