Question

Write the chemical eq. Of the reaction which takes place when iron reacts with dilute sulphuric acid wgat happens when the gas produced is ignited wirh a burning natchstick

Answer 1

Answer :

Balanced Chemical Equation :

Fe(s) + H2SO4 (aq) ------> FeSO4 (aq) + H2(g)

This reaction is related to the displacement reaction in which one of the element takes the position of the another element in a compound if it is highly reactive than another compound.

Here :

1 atom of iron present in the reactant side and in the product side are equal.

2 atoms of hydrogen present in the reactant side and in the product side are equal.

1 atom of sulphur present in the reactant side and in the product side are equal.

4 atoms of oxygen present in the reactant side and in the product side are equal.

Now,

When the hydrogen gas produced is ignited with a burning matchstick because it is a very inflammable gas. It catches fire rapidly.
