It was named Avagadro number for the reason that it was discovered by Amadeo Avagadro, it was named after his last name. The one who in reality initially evaluated the real number of particles in a given substance, was Josef Loschmid. Avagadro was a legal counselor who had an enthusiasm for it, and the reason the number is named after him was a direct result of a French physicist named Jean Baptiste Perrin. Perrin utilized the term as a result of Avagadro's enthusiasm for Brownian movement. What Avagadro had done was assembled everything that researchers had found to help clarify the varieties that existed amongst iotas and atoms. The mole unit is short for the German word molekulargewicht. It was to some degree an aggregate push to build up the idea. Every individual that is said to have found it, is an alternate individual, however these four individuals are the most pertinent

Below is a short historical account of the discovery of the Avogadro's number, including a definition of what this number represents.

Explanation:

The Avogadro's Number - Definition

The Avogadro's number represents the number of units in one mole in a substance. These units may be atoms, electrons, molecules or ions.

The Avogadro's Number - Historical Account

Year: 1808 - Gay-Lussac claimed that two gases, when reacting, the volumes of products and reactants were in whole number ratios; this being one of the fundamental laws of gases (the Combining Volumes Law)Year: 1811 - Avogadro considered that Gay-Lussac's Law of Combining Gases was the key to understand molecular constituency better. Based on this law, he then stated that, at a given temperature and pressure, gas volume would be proportional to the number of molecules or atoms no matter what the nature of the gas is. Year: 1860 - Cannizzaro used Avogadro's hypothesis to come up with a set of atomic weights, which was based on one-sixth of the atomic weight of the oxygen, providing the foundations for more accurately made estimations for the Avogadro's number throughout the following one hundred years.Year 1909 - Perrin coined the name Avogadro's number and gave it a definition: the number of molecules in thirty-two grams of carbon 12. He honored Avogradro due to the contributions he had made about the topic.

Answer from: Quest

answer: the figure is attached herewith.

step-by-step explanation: we are given to sketch a unit circle and label the terminal points corresponding to

$\theta=\dfrac{\pi}{3},~2\dfrac{\pi}{3},~3\dfrac{\pi}{3},~4\dfrac{\pi}{3},~5\dfrac{\pi}{3}.\\\\\\\rightarrow \theta=60^\circ,12^\circ,180^\circ,240^\circ,300^\circ.$

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

Answer from: Quest

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
