Answer: The value of
for chloroform is
when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
Explanation:
Given: Moles of solute = 0.793 mol
Mass of solvent = 0.758

As molality is the number of moles of solute present in kg of solvent. Hence, molality of given solution is calculated as follows.

Now, the values of
is calculated as follows.

where,
i = Van't Hoff factor = 1 (for chloroform)
m = molality
= molal boiling point elevation constant
Substitute the values into above formula as follows.

Thus, we can conclude that the value of
for chloroform is
when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
You should classify it as co2 solid as CO2(s) and that small left comes to the bottom right hand side and dry ice is a form of liquid carbon dioxide so u should write it as CO2(l) and that L comes to the bottom right hand sise
Answer:
In the picture, it's shown that the energy from the sun and carbon dioxide is absorbed by plants through the leaf and is used for cooking food in plants. It is also shown that nutrients and water needed for the plant is absorbed through the roots of the plant. And it's also shown that cooking results in the formation of Glucose and Oxygen in which oxygen is released into the atmospehere and the glucose is stored in the plant for its own needs.
Answer: Option (d) is the correct answer
Explanation:
The energy present within the bonds of the atoms of a compound or molecule is known as chemical energy.
As this energy is present at a position that is, within the bonds hence it is a potential energy. So, whenever there occurs a chemical reaction the stored chemical energy is released.
As potential energy is the energy possessed because of position of a substance. And, kinetic energy is the energy present due to the motion of an object.
Therefore, we can conclude that chemical energy is a form of potential energy.
