What do these two changes have in common? rust forming on a metal gate bleaching clothes Select all that apply. Both are only physical changes. Both are chemical changes. Both are caused by heating.

Both **rust forming on a metal gate** and **bleaching clothes** involve chemical changes. Here's why: 1. **Rust Formation**: - **Chemical Change**: Rust is the result of the oxidation of iron in the presence of water and oxygen, forming iron oxide. This changes the chemical composition of the metal. 2. **Bleaching Clothes**: - **Chemical Change**: Bleaching typically involves chemical agents like chlorine or hydrogen peroxide, which break down and remove stains by altering their chemical structure. Regarding the other options: - **Only Physical Changes**: Neither rust formation nor bleaching clothes are solely physical changes, as both involve alterations in chemical composition. - **Caused by Heating**: While heat can accelerate both processes, heating is not the primary cause of rust formation or the bleaching action itself. **Therefore, the correct statement is:** - **Both are chemical changes.**
