Question

3g of hydrogen reacts with 30g of oxygen to yield H2O .which is limiting reactant?
Given that : H2+ O2= H2O​

Answer 1

Answer:

So, 3g of Hydrogen will react with (3x32) / 4 = 24g of Oxygen. Since, the amount of Oxygen given (30g) is more than the required amount of Oxygen (24g). Thus, oxygen is the excess reagent and hydrogen is the limiting reagent.

Answer 2

Answer:

3g of Hydrogen will react with (3x32) / 4 = 24g of Oxygen. Since, the amount of Oxygen given (30g) is more than the required amount of Oxygen (24g). Thus, oxygen is the excess reagent and hydrogen is the limiting reagent.
