Neutralisation Reaction Equations
They really help in an exam!
Acid + Alkali = Salt and Water
Acid and Metal Carbonate = Salt and Carbon Dioxide
Acid + Metal = Salt and Hydrogen
Acid and Metal Oxide = Salt and Water

Evaporation
is what happens to the liquid
Crystallization is
what happen to a solid as it forms
