Homework Help: Can you help me to balance this ! tnx !

    Ag(subscript of 2)S + HNO(subscript of 2) -> Ag(subs.2)SO(subs.4) + NO(subs.2) +H(subs2)O

    TNX! PO!

    So, Ag2S + HNO2 -> Ag2SO4 + NO2 + H2O ?

    What's being oxidised? What's being reduced? What stays the same?

    In the future, you'll want to ask homework questions under
    Physicsforums -> Science Education -> Homework & Coursework

    There is probably a mistake on your products side. Instead of HNO2, it's probably HNO3, nitric acid. The equation cannot balance with HNO2.

    To find your coefficients:

    Count and mark the number of elements on each side of the reaction.
    Looking at your oxygens should get you the solution quickly.

    Wait, this kind of looks like a dehydration reaction. Make sure about your silver compounds too.
