Question

When ferrous sulphate is heated then what forms​

Answer 1

Explanation:

Hi there !!

When Ferrous sulphate is heated it leaves a reddish brown residue [ ferric oxide --> Fe₂O₃] .

Also ,

Two gases are also evolved.

The gases are : -

Sulphur dioxide (SO₂)

Sulphur trioxide (SO₃ )

heat

FeSO₄ [ s ] ----------> Fe₂O₃ [s ] + SO₂ (g) + SO₃ (g)

heat

2FeSO₄ [ s ] ----------> Fe₂O₃ [s ] + SO₂ (g) + SO₃ (g) ----> balanced equation

This is an example of decomposition reaction

As heat energy is used for this chemical reaction , this chemical reaction is also known as thermal decomposition reaction.

Answer 2

Answer:

In the decomposition of ferrous sulphate or on heating of ferrous sulphate Then ferric oxides, sulphuric dioxide and sulphuric tri oxides formes ⇩⇩⇩⇩⇩

△

FeSO⁴(s) -------->Fe²O³(s) + SO²(g) + SO³(g)

Here

●Ferrous sulphate→ green colour

●Ferric oxide→Brown colour

●Sulphur dioxide →Colour less

●Sulphur trioxide →"" ""
