H2CO3+NaOH=Na2CO3+H20

Explanation:Carbonic acid is a weak acid and Sodium Hydroxide is a weak base. Salt formed is Sodium Carbonate.

2.write name and chemical formula of a salt of strong acid and strong base

Sodium chloride (NaCl) is the salt of strong acid and strong base.

3.When water is added to NaCl it will undergo hydrolysis or not ? why?​

It does not undergo hydrolysis so there is no reaction with water between the NaCl salt ions. NaCl's aqueous solution contains equivalent concentrations of H+ and OH– ions, so it is neutral in nature.
