An inorganic compound (A)\left(A\right) made of two most occurring elements in the earth’s crust and it is used in building construction when made to react with carbon forms a poisonous gas (B)\left(B\right) which is diatomic molecule. Compounds \left(A\right)and(B)and \left(B\right) are

Options

  1. ASiO2,CO2Si{O}_{2}, C{O}_{2}
  2. BSiO2,COSi{O}_{2}, CO
  3. CSiO2,N2Si{O}_{2}, {N}_{2}
  4. DCaO,CO2CaO, C{O}_{2}

Correct answer

B. SiO2,COSi{O}_{2}, CO

Step-by-step solution

SiO2Si{O}_{2} is a compound of oxygen and silicon most abundant elements of earth’s crust and is used in construction.
SiO2+2C→Si+2COSi{O}_{2} + 2C \to Si + 2CO (Poisonous gas and diatomic molecule)
