of and of were taken in a vessel and exploded. Which is the limiting reagent? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Moles } H_2 = 5$. $\text{Moles } O_2 = 2$. <br>Reaction: $2H_2 + O_2 \rightarrow 2H_2O$. <br>2 moles $O_2$ need 4 moles $H_2$. We have 5, so $O_2$ is limiting.
