A metal is treated with dilute sulphuric acid. The gas evolved is collected by the method shown in the figure:

If the metal used above is zinc, choose the correct balanced chemical equation for the evolution of gas?

Options

A. `2Zn_((s)) +H_(2)SO_(4)("dil") to 2ZnSO_(4(aq)) +H_(2(g))uarr`
B. `Zn_((s)) +H_(2)SO_(4)("dill") to ZnSO_(4(aq)) +H_(2(g))uarr`
C. `Zn_((s)) +2H_(2)SO_(4)("dil")to 2ZnSO_(4(aq)) +H_(2(g))uarr`
D. `2Zn_((s)) +H_(2)SO_(4)("dil")to ZnSO_(4(aq)) +2H_(2(g))uarr`

Answer

B

Explanation

The balanced chemical equation is :
`Zn(s) +H_(2)SO_(4)("dil") to ZnSO_(4)(aq) +H_(2)(g)uarr`
