question
all of the following are examples of chemical changes except:
select the correct answer below:
cracking an egg
rusting of metal
burning wood
digesting a steak

Explanation:

A chemical change results in a new substance being formed. Rusting of metal forms metal - oxide, burning wood forms ash and gases, and digesting a steak involves chemical reactions in the body to break down food. Cracking an egg only changes the physical state of the egg by breaking the shell, without forming a new chemical substance.

Answer:

cracking an egg
