### Chemical Reactions of Copper

1. **Copper and Hydrochloric Acid:**
   - **Equation:** \( \text{Cu} + \text{HCl} \rightarrow \text{No Reaction} \)
   - **Explanation:** Copper does not react with hydrochloric acid, indicating that no observable chemical change occurs between these substances.

2. **Copper and Nitric Acid:**
   - **Equation:** \( \text{Cu} + 4\text{H}^+ + 2\text{NO}_3^- \rightarrow \text{Cu}^{2+} + 2\text{H}_2\text{O} \)
   - **Explanation:** In contrast, copper reacts with nitric acid. In this reaction, copper is oxidized, and nitrogen from the nitrate ion undergoes reduction, producing copper ions (\(\text{Cu}^{2+}\)) and water (\(\text{H}_2\text{O}\)). 

These equations illustrate how different acids interact with copper, highlighting the reactivity differences based on acid type.
