Question

3 gm of h2 reacts with 29g of oxygen to yield water. Which one is the limiting reagent

Answer 1

heya....


First write the chemical equation.


2H₂ + O₂ -----> 2H₂O


For 2H₂ - 2 x 2 = 4 g

O₂ - 32 g

2H₂O - 2 x 18 = 36 g


Now, we have to determine the limiting reagent.


4 g of H₂ reacts with 32 g of O₂
1 g of H₂ reacts with 32/4 g of O₂
3 g of H₂ reacts with 32/4 x 3 = 24 g of O₂

But according to the question, 29 g of O₂ is present.


So, the limiting reactant is hydrogen.
