Eight equations, A to H, are listed.
A 2SO2 + O2 -> 2SO3
B C12H26 -> C10H22 + C2H4
C Cl2 + 2KI -> 2KCl + I2
D C6H12O6 -> 2C2H5OH + 2CO2
E N2 + 3H2 -> 2NH3
F 6CO2 + 6H2O -> C6H12O6 + 6O2
G Fe2O3 + 3CO -> 2Fe + 3CO2
H Zn + CuSO4 -> ZnSO4 + Cu
Some equations answer more than one part; others answer none.
