I’m pretty tired right now so I’m not thinking very clearly so this is probably stupidly simple, but I’ve got a bit of a hangup on a question I’m doing.
I’m suppposed to balance this equation assuming it’s in an acid solution (in the presence of H+ ions)
2CuS(s) + HNO3 --> Cu(NO3)2 + H20 + NO (g) + S (s)
Ordinarily I’d balance the half reactions (excluding H and O), add H20 to compensate for O, H+ to compensate for H, and electrons to compensate for charge. But this equation already seems half done. The H2O has been accounted for, etc.
I tried just straight up balancing the equation but it’s sort of unruly. Trying to break it apart into the half reactions also gave me troubles. Any ideas?
EDIT: Forgot to put in the sulphur on the right side of the equation, it’s there now though.
