(3) -(x + y) kJ
(2) (y – X) kJ
(4) (x + y) kg​

Answer 1

Explanation:

Explanation: Acids and Bases exhibit their conducting property only if they are in aqueous solution in which they could completely ionize in water. An acid in water solution dissociates H + ions. Let us consider the reaction between water and hydrochloric acid (HCI). HCI in presence of water produces H + ion. This ion cannot exist alone and hence combines with water molecules and forms H3O +. The reaction is as follows:
