Explanation:
The particular reactants in the Fischer esterification reaction were not stated.
Generally, a Fischer esterification is a reaction that proceeds as follows;
RCOOH + R'OH ⇄RCOOR' + H2O
This reaction occurs in the presence of an acid catalyst.
We can shift the equilibrium of this reaction towards the products side in two ways;
I) use of a large excess of either of the reactants
ii) removal of one of the products as it is formed.
Any of these methods shifts the equilibrium of the Fischer esterification reaction towards the products side.
0.000132 g of hydrated sodium borate (Na₂B₄O₇ · 10 H₂O)
Explanation:
First we need to find the number of moles of sodium borate (Na₂B₄O₇) in the solution:
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume (L)
number of moles of Na₂B₄O₇ = 0.1 × 0.5 = 0.05 moles
We know now that we need 0.05 moles of hydrated sodium borate (Na₂B₄O₇ · 10 H₂O) to make the solution.
Now to find the mass of hydrated sodium borate we use the following formula:
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of hydrated sodium borate = 0.05 / 381 = 0.000132 g

The reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid is Friedel craft alkylation.
In the Friedel craft alkylation cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid. in the first step the cyclohexene produced carbocation in the presence of sulfuric acid by protonation. in the second step the `the carbocation undergoes nucleophilic by the benzene ring and produced cyclohexylbenzene. this is the mechanism followed in the formation of the cyclohexylbenzene by the Friedel craft alkylation.
Thus, The reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid is Friedel craft alkylation.

Answer:
lbm/ft³ or psi/ft
Explanation:
The description in the question shows the density to measured is that of gases (upper atmosphere). The density of a gas can be described as the mass of the gas divided by the volume of the gas at a certain temperature and pressure. It's unit can be represented as lbm/ft³ or psi/ft.
NOTE:
"lbm" means "lean body mass" which is a unit for mass or weight and can be described as the pound mass
"psi" means "pound per square inch"; is also a unit for mass or weight
