Answer:
b. Oxygen
Explanation:
It can be seen that the chemical equation have 2 moles of hydrogen gas that should be reacted with the one mole of oxygen gas
Now for 4.2 moles, the hydrogen gas would be reacted as
= 4.2 × 1 ÷ 2
= 2.1 mole oxygen gas
Therefore the hydrogen would be limited the reagent because it limits the product formation
On the other hand, the oxygen is the excess reagent i.e.
= 3 - 2.1
= 0.9 moles
This would be left for oxygen
Hence, the correct option is b.
