Below are sample questions representative of the exercises included on this worksheet and related 11.142 Particle Diagram and Representation Based Multiple Choice skill assessments:

Problem 1Difficulty: Mastery
Use the cumulative representation: a particle diagram shows H3O+ and OH- combining to make water, and the energy diagram shows products lower than reactants. Which statement best matches both representations?
ANeutralization forms oxygen gas and is endothermic
BThe reaction is a precipitation because all ions become insoluble
CThe particles show sublimation because products are lower in energy
DNeutralization forms water and is exothermic for the represented reaction
Solution & Explanation:The particle diagram shows H3O+ and OH- reacting to form water molecules. Products lower in energy than reactants indicate energy is released, so the represented neutralization is exothermic.
Problem 2Difficulty: Mastery
Use the vapor-pressure and phase diagram representation. At 70 degrees C, a liquid's vapor pressure is greater than the external pressure shown. What will occur?
AThe liquid will freeze because temperature is below the critical point
BThe liquid will condense because high vapor pressure prevents bubbles
CThe liquid will boil because vapor pressure exceeds external pressure
DNothing happens because boiling requires exactly 100 degrees C for every liquid
Solution & Explanation:Boiling occurs when a liquid's vapor pressure equals or exceeds the external pressure. The diagram shows that condition at 70 degrees C for this liquid.
Problem 3Difficulty: Mastery
Use the molecular polarity diagram comparing CO2 and SO2 with bond dipole arrows. Which statement correctly explains the difference?
ACO2 is polar because it has two polar bonds in a straight line
BSO2 is polar because its bent shape prevents S-O bond dipoles from canceling
CSO2 is nonpolar because all molecules with two identical atoms are nonpolar
DBoth are nonpolar because oxygen is present in both molecules
Solution & Explanation:CO2 has two equal C-O dipoles arranged linearly in opposite directions, so they cancel. SO2 is bent, so its S-O bond dipoles do not cancel and the molecule has a net dipole.
