Step-by-step explanation:
12^2 = 144, 9^2 = 81, and 15^2 = 225.

Answer:
It is a chemical change ⇒ 1st answer
Step-by-step explanation:
* Lets explain the statements to solve the problem
- <u><em>A chemical change</em></u> occurs when a new substance is formed through
a chemical reaction
- Ex: cooking an egg
- <u><em>Change of reaction</em></u> is the rate of reaction it can be decreases or
increasing
- <u><em>A phase change</em></u> is a change from one state to another without a
change in chemical composition
- Ex: Condensation: the substance changes from a gas to a liquid
- <u><em>A physical change</em></u>, such as a state change or dissolving, but does
not create a new substance
- Ex: Breaking a glass
* Lets solve the problem
- A piece of toast came out of the toaster very overcooked.
∵ It is like the cooking an egg
∴ It is a chemical change

Hope this Helps!
