When two compounds have same molecular formula but different structural formula, they are said to be
isomers of each other and this phenomenon is called as
isomerism.
Hexane has
six isomers.
The isomers of hexane have a difference in their structure due to parent chain length (
chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.
Answer:
The hydroxide [OH-] concentration of the solution is 1.26*10⁻⁵ M.
Explanation:
The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution.
POH indicates the concentration of hydroxyl ions [OH-] present in a solution and is defined as the negative logarithm of the activity of hydroxide ions (that is, the concentration of OH- ions):
pOH= -log [OH-]
A solution has a pOH of 4.90. Replacing in the definition of pOH:
4.90= -log [OH-]
Solving:
-4.90= log [OH-]
1.26*10⁻⁵ M= [OH-]
<u><em>The hydroxide [OH-] concentration of the solution is 1.26*10⁻⁵ M.</em></u>
I'm not sure what the question is but 3 is an example of a prime number. I hope this help
Ammonium sulfate precipitation is used to separate proteins by function
However, it is one of the most commonly used methods for laboratory scale protein purification and fractionation. This method is also used to separate proteins by altering their solubility.
<h3>What is separation techniques?</h3>
Separation technique is a process or method used to the components of mixtures.
There are different types of separation technique which includes sublimation, precipitation, sieving, evaporation and many more.

Answer:
final concentration: Ca = 0.014 M
Explanation:
Velocity of reaction:
∴ α: order of reaction, assuming α = 1
∴ K = 0.249 s-1.......rate constant
∴ Cao = 0.050 M......initial concentration
∴ t = 5 s.......reaction time
⇒ δCa/δt = K*Ca
⇒ ∫δCa/Ca = K*∫δt
⇒ Ln(Cao/Ca) = K*t = (0.249s-1)(5 s) = 1.245
⇒ Cao/Ca = 3.473
⇒ Ca = 0.050/3.473
⇒ Ca = 0.014 M
