An inorganic compound A 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 which is diatomic molecule. Compounds A and B are

Options

  1. AS i O 2 , C O 2
  2. BS i O 2 , C O
  3. CS i O 2 , N 2
  4. DC a O , C O 2

Correct answer

B. S i O 2 , C O

Step-by-step solution

S i O 2 is a compound of oxygen and silicon most abundant elements of earth’s crust and is used in construction. S i O 2 + 2 C → S i + 2 C O (Poisonous gas and diatomic molecule)
