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

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

We explain by a example

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.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
