Answer:
Chemical change refers to when two or more chemicals react with one another. Leaves changing colour is not a chemical change. Technically the "chemical composition" changes, but chemical change is when the actual chemicals change. The leaves changing colour is the absence of chlorophyll and the presence of other substances that are other colours.
Explanation:
A chemical change is when Chemicals react by coming in contact with each other.
This is what happens when a chemical change occurs
-A new substance is created. (almost always) -the change is irreversible. (always i think)-there is some sort of violence ( not quiet literally violence, it could be that a mixture bubbles up, or pops really loudly)
A good example is baking soda and vinegar
- there is a new substance. it is a gas, and most people don't notice it. try mixing baking soda and vinegar in a jar, and quickly stretch a rubber glove over the top. the glove will fill up
-change is irreversible, you can not get your baking soda and vinegar back
-violence - it bubbles up a lot
