2H2 + O2 - > 2H2O
Explanation:
H2 + O2 - > H2O
The equation can be balance as follows:
There are 2 atoms of O on the left side of the equation and 1atom on the right side. It can be balance by putting 2 in front of H2O as shown below:
H2 + O2 - > 2H2O
Now, there are 4 atoms of H on the right side and 2 atoms on the left side. It can be balance by putting 2 in front of H2 as shown below:
2H2 + O2 - > 2H2O
Now the equation is balanced as the numbers of the atoms of the different elements present on both sides are the same
