Combination reactions happen when two or more things come together to make something new. You can find them all around you! Here are some cool examples:

1. Photosynthesis:

   • Plants take in carbon dioxide and water when there's sunlight. They use these ingredients to create glucose (a type of sugar) and oxygen.

2. Rust Formation:

   • Iron mixes with oxygen when water is around, and this creates rust. This rust is called iron oxide.

3. Making Water:

   • When hydrogen gas combines with oxygen gas, they create water.

These examples show how combination reactions are important not just in nature but also in our daily lives!
