Ответ:
There will be 2 atoms of aluminum and 3 atoms of sulfate
Explanation:
The equation in this case is not balanced.
Let us balance the equation first
The valence of aluminum is +3 and that of sulfate ion is -2
They will form bond only when there valence is equal. Thus in a compound having aluminum and sulfate, there must be 2 atoms of aluminum and 3 atoms of sulfate.
Al2(SO4)3
