Official Answer

Same amount of $H_2$ gas will be evolved.

Same amount of

H_2

gas will be evolved.The amount of

H_2

gas evolved is less.

H_2

gas will not be evolved.In place of

H_2

gas,

O_2

gas will be evolved.

Marking Scheme

1Same amount of $H_2$ gas will be evolved.
2The amount of $H_2$ gas evolved is less.
3 $H_2$ gas will not be evolved.
4In place of $H_2$ gas, $O_2$ gas will be evolved.

Hint

The reaction between zinc and an acid produces hydrogen gas. The type of acid used does not affect the amount of hydrogen gas produced.

Quick Oral Answer

The reaction between zinc and an acid produces hydrogen gas. The type of acid used does not affect the amount of hydrogen gas produced. Therefore, if acetic acid is used instead of dilute sulphuric acid, the same amount of hydrogen gas will be evolved.
