initial condition : Vi = 4.700 L , Ti = 71.0ºC +273 => 344 K
final condition : Vf = 3.300 L , Tf = ?
Pressure is constant:
According to charle's law , volume is directly proportional to temperature at constant pressure !
Hence Vi / Ti = Vf / Tf
4.700 L / 344 K = 3.300 L / Tf
Tf = 3.300 L * 344 K / 4.700 L
Tf = 1135200 / 4.700
Tf = 241.53 K
Tf = 241.53 - 273
Tf = -31.47ºC
Answer:
False
Explanation:
Fossil fuels are used as a source of energy to this day.
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.

Explanation:
The hydroxide ion concentration can easily be calculated from the concentration of the metal hydroxide solutions given as shown in the solution attached. The pH can now be obtained from there using pH+pOH=14. The pH value is always greater than the the pOH value as shown in the solution to the problems attached.
Question (c) contains incorrect data that cannot be used to calculate the required parameters.
