Ten moles of hydrogen are allowed to react with 6 moles of oxygen. How much water will be obtained from the reaction on complete consumption of one gas?

Correct answer: A. 10 moles

  • A. 10 moles
  • B. 8 moles
  • C. 5 moles
  • D. 4 moles

Explanation

The reaction to form water is 2H2 + O2=2H2O.In this reaction we can see that the amount of moles of hydrogen decides the number of moles of water. 10H2O + 5O2 = 10 H2O.(With 6 moles of oxygen we will get an extra mole of oxygen left in the reaction).Therefore we know 10 moles of hydrogen will produce 10 moles of water. Hence option A is correct.
