D, because a medium is a state of matter (solid, liquid, or gas)
The correct name is 3-methylhexane.
<h3>Structures : </h3>
The structure of 4-methylhexane is
CH3
|
CH3-CH2-CH2-CH-CH2-CH3
In the systematic nomenclature, the longest carbon chain is numbered so as to give the lowest number to the substituent.
CH3
|
CH3-CH2-CH2-CH-CH2-CH3
6 5 4 3 2 1
Hence the correct name is 3-methylhexane.
What is 3-methylhexane?
A branching hydrocarbon having two enantiomers is 3-methylhexane. It is one of heptane's isomers. The chirality of the molecule makes it one of only two structural isomers of heptane with this feature, the other being 2,3-dimethylpentane. 3-methylhexane and 3-methylhexane are the enantiomers.
<h3>Rules for naming the compound ? </h3>
- Typically, a molecular molecule consists of two or more nonmetal components.
- Molecular compounds are termed by using the stem of the first element's name plus the suffix -ide, followed by the second element. The number of atoms in a molecule is specified using numerical prefixes.

Answer: 460.624
Explanation:
1. Multiply the numbers
(24.5260 x 2.56) + 397.84
= (62.784) + 397.84
2. Add the numbers
(62.784) + 397.84
= 460.624
Answer:
The natural phenomenon used to describe the length of a meter is the speed of light. The length of a meter is the length a light path travels in 1/(299792458) seconds through a vacuum.
The definition is better due to the uncertainty involved in the use of the length of a standard meter stick because the length of the meter stick could change due to atmospheric conditions from place to place
