Select the appropriate state symbols of the products given as X and Y in the following chemical equation by choosing the correct option from table given below:
Zn( s)+H2SO4(l)→ZnSO4(X)+H2(n)

	X	Y
a	(s)	(l)
b	(aq)	(g)
c	(aq)	(s)
d	(g)	(aq)

Solution:

Metals react with acids to give salt and hydrogen gas. Thus, when zinc reacts with sulphuric acid, it forms zinc sulphate with the liberation of hydrogen gas.
Zn( s)+H2SO4(aq)→ZnSO4(aq)+H2(g)
