Homework Help: Chemistry

Posted by Sara on Friday, June 21, 2013 at 5:11pm.

Either my online portal hates me, or I don't understand how to balance properly.

QUESTION
Balance reaction of arsenic(III) sulfide with nitric acid As2S3(s) + NO3-(aq) → H3AsO4(aq) + S(s) + NO(g)

Is this the correct balanced equation?
32 H2O + 24 As2S3(s) + 80 H+(aq) + 80 NO3-(aq) → 48 H3AsO4(aq) + 9 S8(s) + 80 NO(g)

If yes, which is the oxidizing reagent and what is the reducing reagent?
