If 30 m L of H 2 and 20 m L of O 2 react to form water, what is left at the end of the reaction?

Question

If 30 m L of H 2 and 20 m L of O 2 react to form water, what is left at the end of the reaction?, 10 m L o f H 2, 5 m L o f H 2, 10 m L o f O 2, 5 m L o f O 2

MARKS App · Accepted Answer

2 H 2 + O 2 → 2 H 2 O Combining volume ratio of H 2 and O 2 = 2 : 1 Here H 2 is limiting reactant. 30 m l of H 2 will react with 15 m l of O 2 and 5 m l of O 2 will remain unreacted at the end.
