Question
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:
\[\ce{Zn_{(s)} + H_2SO_{4(l)} ->ZnSO_{4(X)} + H_{2(Y)}}\]
Options
(X) - (s); (Y) - (l)
(X) - (aq); (Y) - (g)
(X) - (aq); (Y) - (s)
(X) - (g); (Y) - (aq)

Solution
(X) - (aq); (Y) - (g)
Explanation:
Salt and hydrogen gas are produced when metals and acids react. As a result, when zinc combines with sulphuric acid, zinc sulphate is formed along with the release of hydrogen gas.
\[\ce{Zn_{(s)} + H_2SO_{4(aq)} ->ZnSO_{4(aq)} + H_{2(g)}}\]
