The gravitational force is related to the distance between two objects because it is inversely proportional to the square of the distance.
<h3>What is the gravitational force?</h3>
The gravitational force refers to the attraction between two different objects due to their masses.
This force (gravitational force) is fundamental for maintaining the distance of objects in the Universe.
In conclusion, the gravitational force is related to the distance between two objects because it is inversely proportional to the square of the distance.

In an unknown liquid, the percentage composition with respect to carbon, hydrogen and iodine is 34.31%, 5.28% and 60.41% respectively.
Let the mass of liquid be 100 g thus, mass of carbon, hydrogen and oxygen will be 34.31 g, 5.28 g and 60.41 g respectively.
To calculate molecular formula of compound, convert mass into number of moles as follows:
![n=\frac{m}{M}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7Bm%7D%7BM%7D)
Molar mass of carbon, hydrogen and iodine is 12 g/mol, 1 g/mol and 126.90 g/mol.
Taking the ratio:
![C:H:I=n_{C}:n_{H}:n_{I}](https://tex.z-dn.net/?f=C%3AH%3AI%3Dn_%7BC%7D%3An_%7BH%7D%3An_%7BI%7D)
Putting the values,
![C:H:I=\frac{34.31 g}{12 g/mol}:\frac{5.28 g}{1 g/mol}:\frac{60.41 g}{126.90 g/mol}=6:11:1](https://tex.z-dn.net/?f=C%3AH%3AI%3D%5Cfrac%7B34.31%20g%7D%7B12%20g%2Fmol%7D%3A%5Cfrac%7B5.28%20g%7D%7B1%20g%2Fmol%7D%3A%5Cfrac%7B60.41%20g%7D%7B126.90%20g%2Fmol%7D%3D6%3A11%3A1)
Thus, molecular formula of compound will be

Chlorine + Calcium --> Ionic Bond
Iron cannot covalently bond as it is a metal
<span>The relationship between the number of carbon atoms and boiling point is inversely proportional. In the alkane series of hydrocarbons, as the number of carbon atoms decreases, the normal boiling point of the compounds decreases. The reason behind this is that longer chains of molecules require more energy to separate the bonds while shorter chains or molecules with lower number of carbon atoms require less energy to break away from each other. Thus, low carbon molecules have lower boiling point.</span>
