When something burns it is which of these: physical or chemical?

Chemical

What are substances on the right called in a chemical equation

products

BALANCE THE EQUATION.

What happens to the particles of a liquid when we add heat energy?

the particles move faster and spread more, it turns into a gas.

An atom that has an electric charge because of losing or gaining electrons

ion

This type of change results in a new substance and can't be reversed.

Chemical change

Each __________ ___________ can hold only a certain number of electrons.

electron shell

_____________ are composed of a single type of atom

Elements

subscript

Neutrons have a __________ charge.

neutral

the amount of space that an object takes up

Volume

Which property could help you identify between aluminium and iron?
