Reactions
A more reactive element displaces a less reactive element from its compound
What is a displacement reaction?
The change of a liquid to a gas without boiling
What is evaporation?

What is the chemical formula for magnesium?
A substance that is made up of only one type of atom
What is an element?
Addition of oxygen
What is an oxidation reaction?
A way to separate insoluble solids from liquids
What is filtration?
A chemical reaction which takes in heat energy from the surroundings, causing the temperature to decrease
