Which of these is an example of a chemical change?

digesting a salad

Answer 1

digesting a salad is your answer

Answer 2

digesting a salad

Step-by-step explanation:

A chemical change is a change that results in a change of the nature and composition of a substance. In other words, there is a rearrangement of the atoms in the reaction. A simple equation is like this:

`reactants = products`

One of the most important feature of a chemical reaction is the change in the state of the reactants.

The products are different.

Hence the digestion of the salad is a chemical reaction because of the micro nutrients formed and waste formed afterwards.
