    1. The problem statement, all variables and given/known data
    Sn(s)+NO3--->SnO2(s)+NO(g)


    2. Relevant equations



    3. The attempt at a solution
    0 |+5 ,-2| |+4,-2| |+2,-2|
    Sn(s)+NO3--->SnO2(s)+NO(g)
    Sn lost 4e reducing agent
    N gain 3e oxidizing agent
    is that right?
    What about oxygen?? do i do the same thing?
