Question

If 32 grams of each H2 and 02 react to give water then:
a) H2 is limiting reactanr
b) O2 is limiting reactant
c) both are in excess
d) o2 is in excess

Answer 1

Answer:

(b) O2 is limiting reactant.

Explanation:

The reactant which is completely used up in the reaction is called a limiting reactant. Here 32 g of O2 requires only 4 g of H2 (hydrogen) to form 36 g of water according to the balanced chemical equation. And Oxygen limits the amount of hydrogen to be used .
