In the reaction 4NH3+5O2--4NO+6H2O.When one mole of ammonia and one mole of Oxygen are made to react to completion then
Correct answer: B. All the oxygen is consumed
- A. 1.2 moles of H2O are produced
- B. All the oxygen is consumed
- C. 0.8 moles of NO is formed
- D. Some ammonia remains unreacted
Explanation
4NH3 => 5O2xNH3 => 1O2x= 0.8molAs oxygen is the limiting factor it will be consumed first.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
