Reactions of the Oxides and Hydroxides with Acids

The white solids react to form colourless solutions. The reactions are neutralisation reactions and are exothermic:
MgO (s) + H2SO4 (aq) → MgSO4 (aq) + H2O (l)
CaO (s) + 2HNO3 (aq) → Ca(NO3)2 (aq) + H2O (l)
Sr(OH)2(s) + 2HCl (aq) → SrCl2 (aq) + 2H2O (l)
Ba(OH)2 (s) + 2HCl (aq) → BaCl2 (aq) + 2H2O (l)
