Balance the following equations using the appropriate coefficients. Remember that balancing one element may
temporarily unbalance another. You will have to correct the imbalance in the final equation. Check your work by
counting the total number of atoms of each element—the numbers should be equal on the reactant and product
sides of the equation. Remember, the equations cannot be balanced by changing subscript numbers!
1. Al + O2 → Al,03
2. CO + H2 + H2O + CH4
3. HgO → Hg + O2
4. CaCO3 + CaO + CO2
5. C + Fe,03 → Fe + CO2
6. Na + H2 + NH3
7. K + H2O → KOH + - H2
P + O2 → P203
9. Ba(OH)2 H2SO4 H2O + BaSO4
10. CaF2 + H2SO4 → CaSO4 + HF
KC104 + KCI
