A small vunt of acetonitrile (CH, CN) is dissolved in a large amount of formaldehyde (H, CO). 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.) KO CU COS → CH, CN HACO solution Use these sketches to answer the questions in the table below. The enthalpy of solution AH Soln is positive when 0,0 CH3CN dissolves in formaldehyde. Use this information to list the stages in order of increasing enthalpy. x ! ? Would heat be absorbed or released if the system moved from Stage A to B?
a) absorbed
b) released
c) neither absorbed nor released
