Answer 2

Let's balance the chemical equations you provided:

1. Li + O2 -> Li2O
2. H2 + O2 -> 2H2O
3. C + O2 -> CO2
4. CH4 + 2O2 -> CO2 + 2H2O
5. 2Ca + O2 -> 2CaO
6. 2H2 + O2 -> 2H2O
7. Si + 2O2 -> SiO2
8. 4PH3 + 8O2 -> P4O10 + 6H2O
9. 2Zn + O2 -> 2ZnO
10. 2H2O2 -> 2H2O + O2
11. P4 + 5O2 -> P4O10
12. CH4O + 2O2 -> CO2 + 2H2O

In equations 4, 8, and 12, I've added the balanced coefficients to form the correct products based on the given reactants.
