Answer:
amount of aspirin dissolved = 0.0031 g
so we can say that this is not affect % yield as amount of aspirin lost is very less
Explanation:
given data
mass of aspirin = 1 g
volume of water = 450 mL
solubility of aspirin temperature = 10° C
volume of water added = 1.4 mL
to find out
how much amount aspirin would be lost
solution
we know the solubility of aspirin is
solubility of aspirin = 
solubility of aspirin =
solubility of aspirin = 2.2 ×
g/mL
so
we can say
amount of aspirin dissolved = solubility of aspirin × volume of water added
put here value
amount of aspirin dissolved = 2.2 ×
× 1.4
amount of aspirin dissolved = 3.1 ×
g
amount of aspirin dissolved = 0.0031 g
so we can say that this is not affect % yield as amount of aspirin lost is very less
Answer : The change in enthalpy of the reaction is, -310 kJ
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The given main reaction is,

The intermediate balanced chemical reaction will be,
(1)

(2)

(3)

Now we will reverse the reaction 1 and multiply reaction 1 by 2, reaction 2 by 2 and reaction 3 by 3 then adding all the equations, we get :
(1)

(2)

(3)

The expression for enthalpy of formation of
will be,



Therefore, the change in enthalpy of the reaction is, -310 kJ
Answer: k = 2.07692
Explanation: Please find the attached files for the solution
The chloroplast of the cell is most likely damaged if the plant cell is no longer capable of capturing energy from sunlight and converting it into chemical energy.
The chloroplast is the structure inside the leaf cell that is known for capturing light energy from the sun.
This light energy is then used to make food that has chemical energy. If a plant cell has a damaged chloroplast or the chloroplast is removed, then it will no longer be able to trap the light energy. As a result, the process of photosynthesis will not occur in the plant cell. The plant cell will not be able to make the chemical energy required for functioning.
