solution
Use these sketches to answer the questions in the table below.
The enthalpy of solution AH.
is positive when
soln
CH3OH dissolves in water. Use this information to
list the stages in order of increasing enthalpy.
O absorbed
Would heat be absorbed or released if the system
moved from Stage A to B?
O released
O neither absorbed nor released
O none
O ionic bonding force
O covalent bonding force
O metal bonding force
What force would oppose or favor the system
moving from Stage A to B? Check all that apply.
O hydrogen-bonding force
O dipole force
O ion-dipole force
O dispersion force
