What are 4 examples of chemical changes?

Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. When exposed to water, iron becomes a mixture of several hydrated iron oxides and hydroxides.

Is baking a cake a chemical change?

When you bake a cake, the ingredients go through a chemical change. A chemical change occurs when the molecules that compose two or more substances are rearranged to form a new substance! When you start baking, you have a mixture of ingredients. After you make your batter, you bake it in an oven and out pops a cake!

Is Melting chocolate a chemical change?

The melting process is a physical change of state from a solid to a liquid. The chocolate doesn’t change chemically and can easily solidify when put to room temperature.

Is Melting ice a chemical change?

1: Ice Melting is a physical change. Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas), freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change.
