The substance doesn't have a specific name. We just say that that substance is being reduced. Remember this mnemonic - OILRIG where "Oxidation is Loss, Reduction is Gain" of electrons.
Explanation:
The given data is as follows.
Refractive index of mixture = 1.456
Refractive index of hexane = 1.375
Refractive index of toulene = 1.497
Let mole fraction of hexane =
and, mole fraction of toulene =
Also, 
or, 
Hence, calculate the mole fraction of hexane as follows.
refractive index mixture= mole fraction hexane × ref index hexane + mole fraction toluene × ref index toluene.
1.456 = 
1.456 = 
0.081 = 
= 
= 0.66
Since, 
= 1 - 0.66
= 0.34
Thus, we can conclude that mole fraction of hexane in your sample is 0.34.
The answer is liquid or solid.
That is a substance that forms a vapor is generally in liquid or solid physical state.
The substance that is in liquid or solid physical state, forms vapor.
When heated solid and liquid can be converted into vapor so the answer is solid or liquid is the physical state that forms vapors.
<h2>Answer:</h2>
pOH = 4.6
<h2>Explanations:</h2>
The sum of pH and pOH of a solution is 14as shown:

Given the following parameter
pH = 9.4
Substitute the given parameters into the formula to have:

Hence the pOH of the solution of pH of 9.4 is 4.6
The biological macromolecule that is made of those monomers is C. Protein.
