Q. 7. Describe the method of balancing a chemical equation taking an example.
Example 1. Let us consider the formation of water from the combination of oxygen and
hydrogen. The following sequential steps be taken to obtain a balanced chemical equation:
() First write the skeletal equation. For example,
H, + 0
HO
Caution: Do not change formula of any constituent while balancing the equation.
on The same total of charges should appear on the left and right side of the equation.
) Make one of the atoms equal on both sides by multiplying a molecule or compound
with an integral number so that the desired element is balanced. It is convenient to start
with the molecule or compound that contains the maximum number of atoms. Here, H.O
contains maximum number of atoms. It contains one short of oxygen atom and so it is
multiplied by 2 as shown​
