1. H+ (aq) + I¯ (aq) + Cr2O72¯
(aq) ---> I2 (g) + Cr3+ (aq) + H2O (l)
2. OH¯ (aq) + NH4+ (aq) ---> H2O (l) + NH3 (g)
3. Mg (s) + Ag+ (aq) ---> Mg2+ (aq) + Ag (s)
4. KClO3 (s)---> KCl (s) + O2
5. H+ (aq) + CO32¯ (aq) ---> CO2 (g) + H2O (l)
6. SO3 (s) + H2O (l) ---> H+ (aq) + HSO4¯ (aq)
7. Ba2+ (aq) + SO42¯ (aq) ---> BaSO4
Cu2+ (aq) + NH3 (aq) ---> Cu(NH3)42+
