Balance the following chemical reaction, and complete the stoichiometry problem:

 

### Chemical Reactions and Stoichiometry

**4. Calcium Carbonate and Sulfuric Acid Reaction**

Calcium carbonate can react with sulfuric acid to produce calcium sulfate, water, and carbon dioxide. In this example, 54.1 g of CaCO3 and 42.4 g of H2SO4 react together and produce 59.2 g of calcium sulfate.

The balanced chemical equation for the reaction is:

\[
\_ \text{CaCO}_3(s) + \_ \text{H}_2\text{SO}_4(aq) \rightarrow \_ \text{CaSO}_4(aq) + \_ \text{H}_2\text{O}(l) + \_ \text{CO}_2(g)
\]

### Exercises:

**i. Find the Limiting Reactant**

To find the limiting reactant, you need to compare the mole ratio of the reactants used in the reaction based on their initial amounts.

**ii. Find the Theoretical Yield of CaSO4**

The theoretical yield can be calculated using stoichiometry by determining the amount of CaSO4 that can be formed from the limiting reactant's moles and the balanced chemical equation.

**iii. Find the Percentage Yield of CaSO4**

The percentage yield is calculated using the actual yield (59.2 g of CaSO4 as mentioned in the problem) and the theoretical yield from the above step.

\[
\% \text{Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100
\]

In summary, this problem involves identifying the limiting reactant, calculating the theoretical yield of calcium sulfate, and determining the percentage yield of calcium sulfate using the provided amounts.
