Activity 1.5 Ncert Science class 10
Procedure: Activity 1.5 asks us to heat ferrous sulphate crystals (aka Green vitriol) in a test tube and see what happens.
Observation: The Green colour of ferrous sulphate changes to brown and peculiar sulphur smell comes out from the test tube.
Inference: Heating ferrous sulphate on test tube leads to decomposition of ferrous sulphate into a ferric oxide which is brown. It also liberates sulphur dioxide gas which has a foul smell.
2FeSO4(S) ———-> Fe2O3(s) + SO2(g) + SO3(g)
Heating
Next: Decomposition of lead nitrate on heating: Activity 1.6 NCERT Science class 10.

Great job ! Its really very helpful.
It is an example of endothermic reaction as we are giving in the heat energy to let the reaction occur
This activity shows exothermic reaction or endothermic reaction
It is nicely explained and it is very helpful for students.
Its a lot helpful to me
Thank you @studdy.in ☺
