Which of the following situations is most favorable for solubility? View Available Hint(s) Which of the following situations is
2 answers:
Answer: Option (a) is the correct answer.
Explanation:
It is known that more is the attraction between molecules of a solute with the solvent molecules then more attraction takes place. Due to this more number of solute particles will dissolve in the solvent.
For example, NaCl is an ionic compound and water is a polar solvent. So, when we dissolve NaCl (solute) in water (solvent) then sodium chloride will completely dissolve in water because like dissolves like.
This also means that due to the strong attraction between NaCl molecules and water molecules the salt dissociates into and
ions.
Thus, we can conclude that out of the given options strong attraction between solute particles situation is most favorable for solubility.

Answer:
39.1 °C
Explanation:
Recall the equation for specific heat:
Where q is the heat, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the change in temperature.
You should know that the specific heat of water is 1 cal/g/C.
Using the information in the question:
The final temperature is about 39.1 °C.
