Which equation represents a conservation of charge? a) 2fe3+ + al 2fe2+ + al3+ b) 2fe3+ + 2al 3fe2+ + 2al3+ c) 3fe3+ + 2al 2fe2+ + 2al3+ d) 3fe3+ + al 3fe2+ + al3+

D

Explanation:

3Fe^3+ + Al ---> 3Fe^2+ + Al^3+

Total charge of reactants = 3 x +3 = +9

Total charge of products = (3 x +2) + (+3) = +9
