The particle diagram shown above represents the dissolution of CuCl(s) assuming an equilibrium concentration for Cu+ ions of abo
ut 4×10^-4M in a saturated solution at 25°C. The equilibrium being represented is shown in the following chemical equation.
CuCl(s)⇄Cu+(aq)+Cl−(aq)
Which of the following changes to the particle diagram will best represent the effect of adding 1.0mL of 4MNaCl to the solution?
A. Some of the Cu+ and Cl− ions combine to form CuCl(s) because the Ksp will be lower than 1.6×10−7.
B. Some of the Cu+ and Cl− ions combine to form CuCl(s) because the molar solubility will be lower than 4×10−4M.
C. More Cu+ and Cl− ions will be in solution because the molar solubility will be higher than 4×10−4M.
D. More Cu+ and Cl− ions will be in solution because the Ksp will be higher than 1.6×10−7.

Answer:
a. ΔΗ > 0, solution feels cold
Explanation:
Hello,
In this case, endothermic process are those in which we can find that the products have more energy than the reactants, therefore energy is absorbed, for which the following equation:
Must be greater than 0 (positive) thereby, for a solution process we find that the solution feels cold, in such a way, answer is a. ΔΗ > 0, solution feels cold.
Regards.
