10 ~g of hydrogen and 64 of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be

Options

  1. A2 ~mol
  2. B3 ~mol
  3. C4 ~mol
  4. D1 ~mol

Correct answer

C. 4 ~mol

Step-by-step solution

Key Idea (i) H ₂+ 1 2 O ₂ H ₂ O (ii) Amount of water produced is decided by limited reactant (ie, the reactant which is used in small amount) aligned & H ₂+ 1 2 O ₂ H ₂ O & 1 ~mol 1 2 ~mol 1 ~mol & 10 2 ~mol 64 32 ~mol & =5 ~mol =2 ~mol & 1 2 molO ₂ gives =1 ~mol H ₂ O & 2 ~mol O ₂ will give =1 2 2=4 ~mol . aligned
