1. The wick of a candle burns, producing light and heat:
- **Chemical Change** (because the wax and wick undergo a chemical reaction to produce new substances, such as carbon dioxide and water, along with light and heat).
2. Hydrogen peroxide fizzes when added to another substance:
- **Chemical Change** (the fizzing indicates a chemical reaction, often the breakdown of hydrogen peroxide into water and oxygen gas when it interacts with certain substances).
- **Chemical Change** (because the wax and wick undergo a chemical reaction to produce new substances, such as carbon dioxide and water, along with light and heat).
