Which formula can be used to calculate the enthalpy of solution?

ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃

Explanation:

The formation of the solution goes through 3 steps:

1- The dissociation of the solute A particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₁ > 0 beause this is an endothermic process.

2- The dissociation of the solvent B particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₂ > 0 because this is an endothermic process.

3- The particles of the solvent and solute are holding together.  It has ΔH₃ < 0 because this is an exothermic process.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

your answer would be “dry”
