Question

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. neither is a limiting reactant b. h₂ c. both are limiting reactants d. o₂

Explanation:

Step1: Identify the stoichiometry

The balanced chemical equation is $2H_2 + O_2
ightarrow2H_2O$. The mole - ratio of $H_2$ to $O_2$ is 2:1.

Step2: Analyze the given amounts

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 $O_2$.

Step3: Determine the limiting reactant

Since both reactants are completely consumed in the reaction according to the stoichiometry, neither is a limiting reactant.

Answer:

a. Neither is a limiting reactant
