Question

2g of ferrous sulphate crystals are heated in boiling tube.
A.State the colour of ferrous sulphate crystals both before and after heating.
B.Name the gases produced during heating.
C.Write the chemical equation for the reaction.

Answer 1

A. the colour of ferrous sulphate crystals green before heating and change to brown after heating .The colour of crystals changes due to the formation of ferric oxide .

B. during heating Sulphur dioxide and sulphur trioxide are produced .

C.2 FeSo4 (s) --------- Fe2O3 (s) + So2 (g) + So3 (g)

Answer 2

Concept Introduction:-

Science is the methodical process of compiling and arranging knowledge about the universe into verifiable, explicable, and predictable hypotheses.

Explanation:-

A question has been provided to us

We need to find the solution to the question

A. The colour of ferrous sulphate crystals green before heating and change to brown after heating. The colour of crystals changes due to the formation of ferric oxide.

B. During heating Sulphur dioxide and sulphur trioxide are produced.

C. The chemical equation for the reaction $2 FeSo_4 (s)+Heat \rightarrow Fe_2O_3(s) + So_2 (g) + So_3 (g)$

Final Answer:-

The correct answer is the colour of ferrous sulphate crystals green before heating and change to brown after heating.
