25.0 grams of ammonium sulfide reacts with 25.0 grams of copper nitrate
A) which reactant is limiting
B) how much of the Excess reactant remains
C) what is the theoratical yield
The limiting reagent is the one that produces the fewest mols of the product. Here is how you calculate mols of the product. Do one calculation per reagent.

To determine the limiting reactant, excess reactant, and theoretical yield, you need to use stoichiometry, which is the calculation of quantities in chemical reactions based on the balanced equation. Here are the steps to find the answers to your questions:
Step 1: Write and balance the chemical equation:
NH42S + 2Cu(NO3)2 → 2NH4NO3 + CuS
Step 2: Convert the masses of the reactants to moles.
- 25.0 grams of ammonium sulfide (NH4
