CHEMISTRY PROBLEMS: BALANCING EQUATIONS
BALANCE THESE EQUATIONS:
1. Al +
C12
> A1C13
2. N2 + H2
> NH3
3. Fe + O2
> Fe2O3
4. C12 + NaBr
> NaCI + Br2
5. C + O2
> CO
6. SO2 + O2
> SO3
7. Na + H2O
> NaOH
+ H2
8. Fe2O3 + C
> Fe +
CO2
9. Ca(OH)2 + HNO3
10. CaO + H2O
> Ca(NO3)2 + H2O
>
Ca(OH)2
^
THESE BALANCING PROBLEMS ARE A BIT HARDER:
11. Cu + O2 + H2O
>
12. Cu + CO2 + O2
> CuCO3
13. AgNO3 +
>
MgCl2
Cu(OH)2
Mg(NO3)2 + AgCt|
14. Sodium chloride reacts with acetic acid to produce hydrochloric acid) and sodium acetate. The reaction is
reversible.
15. Fluorine gas (diatomic) replaces bromine from potassium bromide. The products are bromine and potassium
fluoride.
16. Carbon disulfide burns completely in oxygen to produce sulfur dioxide and carbon dioxide.
17. Ethyl alcohol, C2H5OH, burns completely in oxygen to produce carbon dioxide and water (steam).
