Balance the following equation. then determine the mole ratio of ca(oh)2: al(oh)3.
al2(so4)3 + ca(oh)2 al(oh)3 + caso4?
a) 2: 3
b) 3: 2
c) 1: 2
d) 3: 3
e) 1: 1

Balanced equation:

Al2(SO4)3 +3 Ca(OH)2 ---> 2Al(OH)3 + 3CaSO4?

Check:
Left side: Al:2; [SO4]: 3; Ca: 3; [OH] 3*2 = 6

Rigth side: Al: 2; [OH]: 2*3 = 6; Ca:3; [SO4]: 3

Mole ratio of Ca(OH)2 : Al (OH)3

3 moles of Ca(OH)2: 2moles of Al(OH)3 = 3:2

Option B.
