Five examples of chemical changes include: 1. Rusting of iron - where iron reacts with oxygen to form iron oxide, 2. Combustion of fuels - like burning wood or gasoline, releasing carbon dioxide, 3. Digestion of food - where complex food molecules are broken down into simpler substances, 4. Photosynthesis in plants - converting carbon dioxide and water into glucose and oxygen in the presence of sunlight, 5. Decomposition of organic matter - such as the breakdown of leaves and food waste, which turns complex substances into simpler ones.
FAQs & Answers
- What is a chemical change? A chemical change occurs when substances combine or break down to form new substances with different properties, such as rusting or combustion.
- How is rusting an example of chemical change? Rusting is a chemical change because iron reacts with oxygen in the air to form iron oxide, a new compound with different properties.
- Is photosynthesis a chemical change? Yes, photosynthesis is a chemical change where plants convert carbon dioxide and water into glucose and oxygen using sunlight.
