                Balancing Chemical Reaction Equations
 Balance the following chemical equations by placing coefficients in front of the
 chemical formulas in such a way as to create the same number of each type of
                element on both sides of the chemical equation.

1.    CaO +      C                             CaC2 +       CO

2.    H2O +     N2O5                           HNO3

3.    Mg +      HCl                            MgCl2 +      H2

4.    SiO2 +     C                             SiC +     CO

5.    Fe2O3 +     Al                           Al2O3 +      Fe

6.    NaHCO3                                   Na2CO3 +       CO2 +      H2O

10.   Al2(SO4)3 +      NH4OH                   Al(OH) 3 +     (NH4)2SO4

11.   C3H5(OH) 3 +      HNO3                   C3H5(NO3) 3 +       H2O

12.   C6H12O6                                  C2H5OH +          CO2
