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

Explanation:

Step1: Determine mole - ratio from equation

From the chemical equation $2H_2 + O_2
ightarrow2H_2O$, the mole - ratio of $H_2$ to $O_2$ is 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 exactly with 1 mole of $O_2$.

Answer:

C. Neither is a limiting reactant
