A compound is a substance composed of 2 or more chemical elements.
The model does not represent a compound because it shows two atoms of the same element combined. To be a compound the model would need to contain atoms of different element, represented by different colored balls. Therefore, the picture does not represent a compound. :)
Answer:
a. alkyne
b. alkane
c. alkyne
d. alkene
Explanation:
The general formula for each class of compound is given below
Alkane: 
Alkene: 
Alkyne:
(assuming single multiple bonds)
Now let us classify according to the above formulas:
a. It has two hydrogen atoms less than the two times of carbon atoms hence, it's alkyne
b. It has two hydrogen atoms more than the two times of carbon atoms hence, it's alkane
c. It has two hydrogen atoms less than the two times of carbon atoms hence, it's alkyne
d. It has hydrogen atoms two times of carbon atoms hence, it's alkene
That is a chemical change.. Hope I helped!
2,2-Dimethyloctane is the correct name.
Eight C atoms make up the longest continuous carbon chain, hence the term "octane" for this molecule.
<h3>Description of the chemical structure</h3>
- There are 31 bonds in the 2,2-Dimethyloctane molecule overall (s) There are 5 rotatable bonds and 9 non-H bonds (s).
- Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
- Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
- In the 2,2-Dimethyloctane chemical structure, the carbon atoms are implied to be at the corner(s) and hydrogen atoms coupled to carbon atoms are not mentioned; instead, it is assumed that each carbon atom is connected to enough hydrogen atoms to form four bonds.
- Based on the ball-and-stick model, which shows both the three-dimensional position of the atoms and the bonds tying them together, the 3D chemical structure image of 2,2-Dimethyloctane is created.
- In order to provide a clearer picture of the atoms and bonds throughout the 2,2-Dimethyloctane chemical structure model, the radius of the spheres is thus smaller than the rod lengths.

1) Body tube (Head): The body tube connects the eyepiece to the objective lenses. Arm: The arm connects the body tube to the base of the microscope. Coarse adjustment: Brings the specimen into general focus. Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
2)Microscopes are made up of lenses for magnification, each with their own magnification powers. Depending on the type of lens, it will magnify the specimen according to its focal strength.
3)In simple magnification, light from an object passes through a biconvex lens and is bent (refracted) towards your eye. ... The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x. (Microscopes usually come with a set of objective lenses that can be interchanged to vary the magnification.)
