Al2(so4)3 +
3 ca(oh)2 →
3_caso4 + ? al(oh)3
word equation

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

Explanation:

1 mole of aluminium sulfate on reaction with 3 moles of calcium hydroxide gives 3 moles of calcium sulfate and 2 moles of aluminium hydroxide.

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

here we have 2 moles of aluminium hydroxide so that aluminium on both the side can balance.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:
