Question

H2+O2=H2O
Balance the equation
I am in class 7 th do I need in steps in KHS and RHS ​

Answer 1

Answer:

2H2+O2=2H2O

Explanation:

Because in LHS Hydrogen molecules and Oxygen molecules are 2 in number so we multiply 2 in RHS :- H2+O2=2H2O

but then hydrogen molecules increases in RHS therefore we multiply 2 with H2 in LHS and hence we got :- 2H2+O2=2H2O

I hope you understand....please mark me as brainlist

Answer 2

The balanced chemical equation is

2H2 + O2 = 2H2O2

Explanation is in the attachment
