Balance the following equations.

1. H2 + 02 ---> H2O 2. H2 + Cl, ---> HCI 3. 02- 4. Na + H20 5. Fe + CuSO4 6. Zn + HCl ---> ZnCl2 + H2 7. KCIO3 ---> KCI + 02 8. Sg + F2 --> SF, 9. Fe + 02 10. C2H6 + O2 ---> CO2 + H20 11. Balance these three equations using fractional coefficients: S8 + F2 ---> SF6 CH10 + 02 ---> CO2 + H20 S8 + Og ---> SO2 12. H2 + O3 ---> H2O (You must balance it with one restriction: the coefficient in front of the water must be a one.) 13. Na + NH3 ---> NANH2 + H2 (balance with a fraction) 14. Pa + 02 ---> P2O5 15. N2 + 02 ---> N2O5 16. KFE3AISI:O10(OH)2 + Cu + O2 + H2S --> KAIS;Og + CuFeS2 + H20 17. SiO, + CaC2 ---> Si + Cao + CO2 18. NH:(g) + O2(g) 19. MgNH4PO4 ---> Mg P.O, + NH3 + Hz0 20. Balance: PCls + H20- ---> O3 ---> NaOH + H2 --> Cu + FeSO4 ---> Fe203 ---> NO2(g) + H2O(g) H&PO4 + HCl using the LCM method.
