D its gravity so yup I just help u
The formula for population density is Dp= N/A, where Dp is the population density, N is the total population, and A is the land area covered by the population. For human populations, A is typically expressed as square miles or square kilometers.
The population density of a country or city or other place is a number showing how crowded that place is. ... For example, France has a population of 60,561,200, and an area of 551,695 square kilometres, so its population density is about 109.8 persons per square kilometre.

- The EPA controls the distribution, production, processing, and handling of chemicals and pollutants.
- Assuring the Safety of Chemicals so that it does not cause any harm to the environment.
<em>:-)</em><em> </em><em>In chemistry, the history of molecular theory traces the origins of the concept or idea of the existence of strong chemical bonds between two or more atoms. The first people to suggest that the world was made of atoms were Democritus and Leucippes(most people of this time believed the world was made from the elements fire, water, earth and wind). However who actually ‘discovered’ is unclear because conceptions happened way before they were seen so it is hard to debate.</em>

<em>The modern structure of benzene was first proposed by Kekule in 1865, then confirmed by Kathleen Longsdale: a crystallographer. He was the first known person to use a model similar to the one we use today- evident in the double carbon bonds .</em>

<em>In 1718, Etienne Francois Geoffrey produced what is known as an affinity table. It’s purpose was to show all the elements that could be combined to make molecules. This shows us that anybody after this can be ruled out because these molecules were scientifically proven to exist before them.</em>
===========================================
<em>However, in the 17th century we finally get our answer. In 1661, Robert Boyle created The Sceptical Chymist, which proved, and named, molecule’s existence.</em>
