Yes! Balance with both H20 and H+

Thanks so if you had 3H+ ions on one side of the equation and H+ ion on the other side would they cancel to give 2H+ thanks

Yep, but you have to add the H20 first to either side (as the oxygen needs to be balanced from your original equation)

The H+ is essentially the final step to balancing the hydrogen ions

FeS2

Well Iron has a normal oxidation state of +2.

I'm sure you can now work out why sulfur is -1
