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.
