Question

For the given reaction
H₂ + O2 H₂O
Eq. wt. of Oz and H2O can be correctly given by​

Answer 1

The given reaction is H

2

O+

1

O

2

+2e

−

⟶2OH

−

Multiply this reaction with 2.

2H

2

O+O

2

+4e

−

⟶4OH

−

Thus, 1 mole of oxygen accepts 4 moles of electrons.

Hence, the equivalent weight of O

2

is one-fourth of molecular weight.

Equivalent mass=

Number of electrons transferred

=8

Hence, the equivalent weight of O

2

in the given reaction is 8.

Answer 2

Answer:

yes it is not correct H2o+O2
