Answer 2

Here is your answer.
(i) Closure property : 

The sum of any two rational numbers is always a rational number. This is called ‘Closure property of addition’ of rational numbers. Thus, Q is closed under addition

(ii) Commutative property : 

Addition of two rational numbers is commutative.

(iii) Associative property :

Addition of rational numbers is associative.

(iv) Additive identity :

The sum of any rational number and zero is the rational number itself
