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)

Answer 1

(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.

\[\ce{Zn_{(s)} + H_2SO_{4(aq)} ->ZnSO_{4(aq)} + H_{2(g)}}\]
