determine the amount

Question

Use balanced chemical equations to relate amounts of reactants and products.

The unbalanced equation for the reaction between ammonia and oxygen gas is shown below.

Balance the equation (enter the smallest integer possible in each box, including the integer "1" when needed) and determine the amount of O₂ consumed and the amounts of NO and H₂O produced when 0.162 mol of NH₃ reacts.

___NH₃ (g) + ____O₂ (g)  ____NO (g) + ___H₂O (g)

______ mol O₂ consumed

______ mol NO produced

_______ mol H₂O produced

Answer 1

4NH₃(g) + 5O₂(g) ==> 4NO(g) + 6H₂O(g) ... balanced equation

mol O₂ consumed = 0.162 mol NH₃ x 5 mol O₂/4 mol NH₃ = 0.203 mol O₂ consumed

mol NO produced = 0.162 mol NH₃ x 4 mol NO/4 mol NH₃ = 0.162 mol NO produced

mol H₂O produced = 0.162 mol NH₃ x 6 mol H₂O/4 mol NH₃ = 0.243 mol H₂O produced
