Question

Answer please with reason

Answer 1

Answer:

X is Green Vitriol and green vitriol is hydrated ferrous Sulphate(FeSO4. 7H2O).

Y is anhydrous ferrous Sulphate (FeSO4) as on heating ferrous sulphate it decomposes into a brown solid ferric oxide(Fe2O3) and two gases.

The two gases are Sulphur dioxide(SO2) and Sulpur trioxide (SO3).

SO3 is already mentioned there so Z is Sulphur dioxide (SO2).

The first reaction will be:

FeSO4. 7H2O ==> FeSO4 + 7H2O

The second reaction will be:

2FeSO4 ==> Fe2O3 + SO2(g) + SO3(g)

Hope this will help u.

Answer 2
