Question

An amorphous solid (X) burns in air to form a gas (Y) which turns lime water milky. This gas decolourises aqueous solution of acidified KMnO4. Gas (Y) reacts with oxygen to give another gas (Z) which is responsible for acid rain. X, Y, and Z are:
  1. S(X),SO2(Y),SO3(Z)
  2. P(X),P2O3(Y),P2O5(Z)
  3. S(X),SO3(Y),CO2(Z)
  4. C(X),CO(Y),CO2(Z)

A
S(X),SO2(Y),SO3(Z)
B
S(X),SO3(Y),CO2(Z)
C
C(X),CO(Y),CO2(Z)
D
P(X),P2O3(Y),P2O5(Z)
Solution
Verified by Toppr

Hence as shown in above image: X=S , Y=SO2 , Z=SO3

Therefore, option B is correct.
