#### Key Questions

1. **What is a gas-evolution reaction? Give an example.**
2. **What reactant types give rise to gas-evolution reactions?**
3. **What is an oxidation–reduction reaction? Give an example.**
4. **What are oxidation states?**
5. **How can oxidation states be used to identify redox reactions?**
6. **What happens to a substance when it becomes oxidized? Reduced?**

31. **Dilution of HNO₃**
   - To what volume should you dilute 50.0 mL of a 12 M stock HNO₃ solution to obtain a 0.100 M HNO₃ solution?
   - *Missed this?* Read Section 5.2; Watch KCV 5.2, IWE 5.3

32. **Dilution of H₂SO₄**
   - To what volume should you dilute 25 mL of a 10.0 M H₂SO₄ solution to obtain a 0.150 M H₂SO₄ solution?

33. **Precipitation Reaction**
   - Consider the precipitation reaction:
     \[
     2 \text{Na}_3\text{PO}_4(\text{aq}) + 3 \text{CuCl}_2(\text{aq}) \rightarrow \text{Cu}_3(\text{PO}_4)_2(\text{s
