A main goal of most environmental scientists is to achieve biodiversity.
The 6 models of the atom:
1. John Dalton's atomic model: Daltons Billiard Ball (Solid Sphere) Model
2. J.J. Thomson's model: Plum Pudding model
3. Ernest Rutherford's model: Nuclear model
4. Niels Bohr's model: Planetary model
5. Erwin Schrdinger's model: Electron Cloud Model/Quantum Model
6. Wave mechanical model
<h3>Atom</h3>
The smallest component that makes up a chemical element is an atom. Atoms that are neutral or ionized are the building blocks of all solids, liquids, gases, and plasma. A normal atom is 100 picometers across, which is incredibly small. Because of quantum effects, they are so small that it is impossible to predict their behavior with sufficient precision using classical physics, as if they were, say, tennis balls. One or more electrons are attached to the nucleus of every atom, which is made up of a nucleus. Protons and neutrons, in various numbers, make up the nucleus. Neutrons exist only in the most prevalent type of hydrogen. An atom's nucleus makes up more than 99.94% of its mass.

The molar mass or As is 74.9g. Start with 281g multiply by (1mol/74.9g) = 3.75 mols
Put what you don’t want on the bottom (in this case grams) so they the u it’s cancel (if you multiply by grams and the divide by grams they cancel. Ultimately leave what you want on the top ( This case mols) then do the math
Answer: Different parts of the sun rotate at different rates.
Explanation:
The statement that best describes the motion of the sun is that different parts of the sun rotate at different rates.
First and foremost, we should note that the rotation of the sun is on its axis and also the sun isn't a solid. Due to this, its motion will be that there'll be rotation of different part of it at different rates. Assuming the sun was solid, then all of its parts will move together.
