Balancing equations
Hi, I am a student taking Chemistry at GCSE standard, and I have some problems with these equations for hw:
The hw states :
Balance these equations:
a) NH3 + O2 + H2O --> HNO3
b) PB(NO3)2 --> PBO2 + NO2 + O2
c) AL + HCL --> ALCL3 + H2
d) C2H5OH + O2 --> CO2 +H20
e) NA2CO3 + HCL --> NACL + H20 + CO2
I wonder if you could give me some help here please. Some pointers would be appreciated.
