Expert Answer:

to balance count the number of atoms of each kind on either side of the equation. than start with the highest number and balance one by one on each side.

H2 + O2 H2O

                     L.H.S               R.H.S

1. H                 2                         2

2. O                  2                        1

so make o 2 on R.H.S by this H is 4 on RHS so make 2 H on LHS.

2H2 + O2 2H2O
