Sodium hydroxide and hydrochloric acid react as shown in this equation

1.	Sodium hydroxide and hydrochloric acid react as shown in this equation. NaOH_((aq))+HCl_((aq))toNaCl_((aq))+H_(2)O_((I)) (i)Which type of chemical reaction in this? (ii)The reaction is exothermic .Explain what that means. (iii)Differentiate exothermic reaction and endothermic reaction. (iv)What happens to the temprature of the solution as the solution as the chemicals react?
Answer» Solution :(i)It ISO neutralisation reaction. (ii)Exothermic reaction is a chemical reaction in which evolution of HEAT energy takes place. (iii) (IV)When NaOH reacts with HCl to give NaCl and water ,heat is evolved.So the solution.s temprature INCREASES.
