Answer 1

Given equation is: H2 + O2 —> H2O

Here in left side of the equation:

Number of H atom is 2

Number of O atom is 2

In right side of the equation:

Number of H atom is 2

Number of O atom is 1

Thus, O atom is not balance and to balance we have to multiply 2 in right side.

H2 + O2 —> 2 H2O

Now, in right side number of H atom is 4 thus to balance it with left side we have to multiply 2 with H2 in left side.

Now,

2 H2 + O2 —> 2 H2O

Now, this reaction is balanced.

Hence, balanced reaction is:

2 H2 + O2 —> 2 H2O
