Question

1. in the chemical equation 2h₂ + o₂ → 2h₂o, if you have 2 moles of h₂ and 1 mole of o₂, which is the limiting reactant? a. both are limiting reactants b. neither is a limiting reactant c. h₂ d. o₂

Explanation:

Step1: Determine mole - ratio from equation

The balanced chemical equation $2H_2+O_2
ightarrow 2H_2O$ has a mole - ratio of $H_2$ to $O_2$ as 2:1.

Step2: Analyze given moles

We have 2 moles of $H_2$ and 1 mole of $O_2$. According to the mole - ratio, 2 moles of $H_2$ react completely with 1 mole of $O_2$.

Answer:

B. Neither is a limiting reactant
