1. magnesium hydroxide and hydrochloric acid

`Mg(OH)2 (s) + 2 HCl (aq) -> MgCl2 (aq) + 2H2O (l)`

  Salt: Magnesium chloride, MgCl2

2. potassium hydroxide and acetic acid

`KOH (aq) + CH3COOH (aq) -> CH3COOK (aq) + H2O (l)`

  Salt: Potassium acetate, CH3COOK

3. sodium carbonate and sulfuric acid**

`Na2CO3 (aq) + H2SO4 (aq) -> Na2SO4 (aq) + H2O (l) + CO2 (g)`

  Salt: Sodium sulfate, Na2SO4

 

**The third reaction produces carbonic acid, `H2CO3` but will further decompose to water and carbon dioxide gas.
