Question

Balance both the atoms and charges of the following chemical equation:
Ce4+ + S2 −→ Ce3+ + S

This is what I came up with:
3Ce4+ + S2 −→ 4Ce3+ + 2S

Answer 1

Correct

Answer 2

Nope. Note correct. The atoms don't balance (4Ce on right and 3 on left as well as 1 S on left and 2 on right) and charges don't balance (10+ on left and 12+ on right).

2Ce^4+ + S^2- ==> 2Ce^3+ + S
