Which set of interactions involved in successfully forming a solution must have positive enthalpy changes? View Available Hint(s) Which set of interactions involved in successfully forming a solution must have positive enthalpy changes? only the interaction of solvent molecules as they are attracted to solute particles separating solvent particles in the pure solvent and the interaction of solvent molecules as they are attracted to solute particles separating solute particles in the pure solute and the interaction of solvent molecules as they are attracted to solute particles separating solute particles in the pure solute and separating solvent particles in pure solvent

Answer 1

Answer:

separating solute particles in the pure solute and separating solvent particles in pure solvent

Explanation:

when we talk about a solution, it means the homogeneous mixture of different substances of two or more.

Enthalpy change of solution is the quantity of heat that is released during the process of dissolving.

If solute molecules have been broken from the intermolecular forces that bind them and also solvent molecules have been broken from the intermolecular forces binding them, then we have an endothermic process.

so the answer is:

separating solute particles in the pure solute and separating solvent particles in pure solvent
