A small amount of sodium chloride (NaCl) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) A NaCl H₂O Use these sketches to answer the questions in the table below. ΔΗ, AH soln B The enthalpy of solution NaCl dissolves in water. Use this information to list the stages in order of increasing enthalpy. is positive when Would heat be absorbed or released if the system moved from Stage C to D? What force would oppose or favor the system moving from Stage C to D? Check all that apply.
