Question

How do you count the total number of atoms present on one side of a chemical equation?

Answer 1

Explanation: We use a different element in the chemical equation.

We explain by a example

`2Na + Cl_(2)\rightarrow2NaCl`

In this equation, we use the two elements Na and Cl.

Now, we count the number of atoms present on one side 2 atoms of Na and 2 atoms of Cl then the total numbers will be 4 .

But , we use a molecular formula then we count the number of each element of the molecular formula.
