Answer:
In Cl
, the 2 is a subscript because it indicates there are 2 of the same elements. The Lewis structure would display it as Cl-Cl.
On the other hand, a superscript would indicate a specific charge.
All subscripts show the amount of the specific element there is.
An example would be O
or N, they both show that there are 2 of the same elements.
If the subscript is outside a parenthesis such as 
it indicates there are 2 
molecules.
The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
<h3>What is atomic mass of an element?</h3>
Atomic mass of an element is the sum of the masses of the protons and neutrons in the nucleus of an atom.
<h3>Why is the atomic mass of Nitrogen-14 and Nitrogen-15 different?</h3>
The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is due to the difference in the number of neutrons.
Nitogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
Therefore, the difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.

The equation of the function is assumed to be a straight line is of the form,
, where 
are the gradient and the y intercept respectively.
The gradient is computed using the formula for the gradient, i.e
.
The equation of the line is,
The equation of the function is ,
.
The value of the x-coordinate when the y coordinate is 0 is found as shown below.
.
so the x-coordinate is 1.
gain, you add anything to the beaker there's going to be a gain in weight since there's more stuff there
