Question

A green colour solid X when heated give rise to reddish brown solid Y and two gases R and S.
a)write chemical name and chemical formula of green colour solid X.
b)write chemical name and chemical formula of reddish brown solid Y
c)write chemical name and chemical formula of two gases R and S.
d)write chemical equation.

Answer 1

Ferrous sulphate FeSO4
Ferric oxide FeO
sulphur dioxide
sulphur trioxide

Answer 2

Hey dear,

● Answers -
a) X => FeSO4 (Ferrous sulphate)

b) Y => Fe2O3 (Ferric oxide)

c) R => SO2 (Sulphur dioxide)
S => SO3 (Sulphur trioxide)

d) Chemical reaction is -
2FeSO4 ---> Fe2O3 + SO2 + SO3

● Explaination -
- When green coloured ferrous sulphate (FeSO4) is heated it decomposes to ferric oxide (Fe2O3) and liberates gases sulphur dioxide (SO2) & sulphur trioxide (SO3).
2FeSO4 ---> Fe2O3 + SO2 + SO3

Hope this helps you...
