(ii) Represant the above Reaction chemically


Please help who will answer my question i will mark them as Brainest​

Answer 1

Answer:

The pale green colour substance is Ferrous sulphate.

the reddish brown solid formed is ferric oxide and the gases evolved are sulphur dioxide and carbon dioxide.

reaction :

 2FeSO4(s)        −→heat Fe2O3(s)         +SO2(g)            + SO3(g)

hope it helps u....

Answer 2

pale green salt is ferrous sulphate that changes its colour into reddish brown and changes into ferric oxide...

gas liberated after the reaction is sulphur dioxide and sulphur trioxide....

chemical reaction :
2FeSO4 -----> Fe2O3 + SO3 + SO2

hope it will be helpful....
