The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
After chilling the drum, the volume will get reduced and it can be found as,
V2 =
=
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.

<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases.
Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases.
For the given chemical reaction:
The half reactions for the above reaction are:
Oxidation half reaction:
Reduction half reaction:
From the above reactions, copper is loosing its electrons. Thus, it is getting oxidized.
Silver ion is gaining electrons and thus is getting reduced.
Hence, the correct answer is Option A.
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:
0.404 mol / L
Explanation:
The <em>total moles of barium chloride</em> can be calculated from <em>the volume and concentration of the stock solution</em>:
1.39 mol/L * 0.180 L = 0.2502 moles barium chloride
Now we <u>calculate the concentration of the working solution, by dividing the total moles by the final volume</u>:
0.2502 mol / 0.620 L = 0.404 mol / L
