Question

In the reaction 2H, + O2 + 2H,0, if you have 3 moles of Hydrogen and 1 mole of oxygen, which is the limiting reactant?
Hydrogen
O Oxygen

Answer 1

Answer:

O₂

Explanation:

A quick way to determine Limiting Reactant => divide moles of each substance given in problem by respective coefficient of balanced equation ... the smaller resulting value is the Limiting Reactant.

                  2H₂        +         O₂        => 2H₂O

Given:   3 moles H₂       1mole O₂

=>            3/2 = 1.5             1/1 = 1

=>   O₂ is Limiting Reactant
