I need help balancing equations
4) C2H6+O2 -->CO2+H2O
5) Pb(NO3)2 + NaI--> PbI2+NaNO3
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
