Concept: Balancing Chemical Reactions

Problem: Balance the following equations:(g) Al(s) + H2SO4(aq) ⟶ Al2(SO4)3(s) + H2(g)

FREE Expert Solution

Unbalanced reaction:

Al(s) + H2SO4(aq) ⟶ Al2(SO4)3(s) + H2(g)

To balance, we look at each element/ion then count the number for each side. We then add a coefficient to the side with less number of that element to balance. 

Both the reactant and product side has SOor  SO42- as the polyatomic ion. We don't see any other S or O in the other compounds in the reaction aside from the ones in SO42- This means we can treat it as one particle to make our balance easy.
