Solid: vibrating at fixed position, because they have a strong force of attraction
Liquid: molecules sliding over each other, because they have a weaker force of attraction than solids
Gas: molecules moving freely at random directions, because they almost have no force of attraction

Assuming that the complete question is the following:
Calcium hydroxide reacts with Aluminum sulfate to form aluminum hydroxide and calcium sulfate. Write the balanced formula unit equation for the reaction.
Then the balanced formula unit equation would be:
3Ca(OH)₂ + Al₂(SO₄)₃ → 2Al(OH)₃ + 3CaSO₄
This is a double replacement reaction, where the cations and anions are interchanged.
Balancing this reaction is based on the Law of Conservation of Mass, which estates that matter is not created nor destroyed, meaning that the number of atoms at the right and the left of the chemical equation needs to be the same. We add coefficients in front of each species that intervenes in the reaction in order to achieve that equality.
Have a nice day!
