Acids react with bases, such as group 1 metal oxides, to give a salt and water.
The equation shows hydrochloric acid reacting with caesium oxide.
2HCl + 2Cs2O → CsCl + H2O
True or false, the chemical equation shown above is balanced?
Acids react with bases, such as group 2 metal oxides, to give a salt and water.
The equation shows sulfuric acid reacting with calcium oxide.
H2SO4 + 2CaO → CaSO4 + H2O
