I need help balancing equations
1) CH4+O2-->CO2-->+H2O
2) Hf+N2-->Hf3N4
3) Mg+H2SO4-->MgSO4+H2
4) C2H6+O2 -->CO2+H2O
5) Pb(NO3)2 + NaI--> PbI2+NaNO3
6) Fe+O2-->Fe3O4

    It won't do any good for us to just give you the answers. You need to learn to do these yourself; I'm sure you want to do that too. What is you big hang up with these problems. Most look like redox equations.

    1) ch4 + 2O2 =) co2 + 2h2o
    2) don't know how
    3) Mg + H2SO4 =) Mgso4 +h2
    4) 2C2H6 + 7O2 =)4CO2 +6H20
    5)PB(NO3)2 + 2NAI =)PBI2 +2NANO3
    6) 3Fe + 2O2 =)FePr
