A mixture of and in mole ratio is exploded. If the initial volume was , what is the final volume of — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$2H_2 + O_2 \rightarrow 2H_2O(g)$. <br>Initial: $20 \text{ mL } H_2 + 10 \text{ mL } O_2 = 30 \text{ mL}$. <br>Since they are in stoichiometric ratio, both react completely. <br>Product volume $= \text{Vol of } H_2 \text{ reacted} = 20 \text{ mL}$.
