Question

Ten moles of hydrogen are allowed to react with 6 moles of oxygen. How much water will be

obtained from reaction on complete consumption of one gas?

Answer 1

10 moles of water are produced,

Step-by-step explanation:

Given data:

Moles of H = 10 mol

Moles of O = 6 mol

Water obtained = ?

Solution:

Balance chemical equation:

2H₂ + O₂ → 2H₂O

Now we will compare the moles of H₂ and O₂ with water from balance chemical equation.

H₂ : H₂O

2 : 2

10 : 10

O₂ : H₂O

1 : 2

6 : 2×6 = 12

Number of moles of water produced by hydrogen are less so hydrogen will be limiting reactant and it will limit the yield of water thus, 10 moles of water are produced.
