Hello!
In this case, according to the given balanced chemical reaction:
We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:
Best regards!

Answer:
The answer to this question is 3. Kinetic energy decreases as temperature decreases.
Explanation:
The average Kinetic energy is given by
× × T where
K = The average molecular kinetic energy of the gas (J)
= Boltzmann's constant (1.38× J/K)
T = Temperature of the gas in Kelvin (k)
When the temperature of a given mass of gas drops average kinetic energy of the molecules goes down and the average molecular speed decreases. The lower kinetic energy which is the energy of motion of the molecules indicates lower speed of the molecules.
Note that, the kinetic energy and average speed are related by the following formula
KE = ×m×v²
Where KE = Kinetic energy in Joules (J)
v = the velocity in m/s and
m = the mass of the molecule in Kg
Answer: Its esterification reaction.
when organic acid react with alcohol it forms ester and water. reaction is known as esterification reaction.
CH3COOH + C2H5OH → CH3COOC2H5 + H2O
ethanoic acid + ethanol → ethyl acetate + water
this reaction takes place in the presence of acid catalyst ( dil H2SO4).
in this reaction oxygen of ethanol with lone pair act as nucleophile and carbonyl carbon of acetic acid act as electrophile.. so its nucleophilic substitution reaction of -COOH group.
