### Preparation of Copper Metal from Copper OreCopper metal can be prepared by roasting copper ore. The ore can contain cuprite (\( \text{Cu}_2\text{S} \)) and copper(II) sulfide (\( \text{CuS} \)).#### Relevant Chemical Reactions1. For cuprite:\[ \text{Cu}_2\text{S}(s) + \text{O}_2(g) \rightarrow 2 \text{Cu}(s) + \text{SO}_2(g) \]2. For copper(II) sulfide:\[ \text{CuS}(s) + \text{O}_2(g) \rightarrow \text{Cu}(s) + \text{SO}_2(g) \]#### Problem StatementSuppose an ore sample contains 10.0% impurity in addition to a mixture of \( \text{CuS} \) and \( \text{Cu}_2\text{S} \). Heating 100.0 g of the mixture produces 75.8 g of copper metal with a purity of 91.1%. What are the weight percent of \( \text{CuS} \) and \( \text{Cu}_2\text{S} \) in the ore?#### Calculation Requirements- **Weight percent of \( \text{CuS} \)** in the ore: \[ \boxed{\text{Weight percent of CuS} \: \%} \]- **Weight percent of \( \text{Cu}_2\text{S} \)** in the ore: \[ \boxed{\text{Weight percent of Cu}_2\text{S} \: \%} \]### Steps to Solve the Problem:1. Calculate the actual weight of copper produced from the reaction.2. Determine the total weight of copper that can be produced from the given weights of \( \text{CuS} \) and \( \text{Cu}_2\text{S} \).3. Use stoichiometry to relate the masses of \( \text{CuS} \) and \( \text{Cu}_2\text{S} \) to the masses of copper produced.4. Develop equations using the known purity and total mass.5. Solve for the weights of \( \text{CuS} \) and \( \text{Cu}_2
