Question

Write observation with reaction for the following : Granulated zinc reacts with dil. sulphuric acid.

Answer 1

Hi friend,

The reaction of zinc with dilute sulphuric acid occurs with the evolution of Hydrogen gas(H2).

The balanced reaction is

Zn + H2SO4 -> ZnSO4 + H2

Hope this helped you a little!!!

Answer 2

Answer: A gas is released burns with a pop sound when a matchstick is bought near it.

Explanation:

Single displacement reaction is defined as the reaction in which a more reactive element displaces a less reactive element from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

$AB+C\rightarrow CB+A$

B is more reactive metal than metal A.

The chemical equation for the reaction of zinc and sulfuric acid follows:

$Zn+H_2SO_4\rightarrow ZnSO_4+H_2$

The hydrogen gas released burns with a pop sound when a matchstick is bought near it.
