1 pts
Given the following Chemical equation, please determine the total number of atoms in the
highlighted product:
Al (s) + H2SO4 (aq) --> Al2(SO4)3 (aq) + H2 (g)


Highlighted- Al2(SO4)3

Answer 1

Answer:

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
