You have a solution of 1.03 g of magnesium sulfate (MgSO4, MM=120.4 g/mol) dissolved in 10.0 g of water. You can assume the solution has ideal behavior. What is the freezing point of the solution? The freezing point of water is 0.00 °C and K = 1.86 °C/m. O-1.64 °C O-4.92 °C O none of the answers are correct O2.78 °C

Which of the following aqueous solutions will have the highest boiling point? Select one: Oa. 0.04 m sodium sulfate, Na₂SO4 Ob. 0.1 m magnesium sulfate, MgSO4 Oc. 0.08 m magnesium chloride, MgCl₂ O d. 0.1 m potassium chloride, KCI e. 0.05 m sodium chloride, NaCl N

✓mall amount of acetonitrile (CH₂CN) 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.) CH₂CN 98 B H₂O Use these sketches to answer the questions in the table below. The enthalpy of solution AH soln is negative when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. Would heat be absorbed or released if the system moved from Stage A to B? What force would oppose or favor the system moving from Stage A to B? Check all that apply. 0 O absorbed O released O neither absorbed nor released none Olonic bonding force O covalent bonding force metal bonding force Ohydrogen-bonding force dipole force ion-dipole force Odispersion force 0.0.
