Study Guide for Chapter 11 and Notes for the
Final
WNC, Chem 121; 05/11/14 JS
Ch. 11 Intermolecular forces – sections 1 – 7 (Heating Curve for Water)
NOTES on the Final Exam (Tuesday 5/13 AND Thursday 5/15; 11:00am – 12:15pm; CED 315)
Preparation:
The Final will cover all chapters (Ch 1 through Ch 11.7) evenly. These will be broken into two halves: roughly First Day: Ch 1-5 (Exam 1&2), Second Day: Ch 6-11.7 (Exam 3&4 + this study Guide). Some overlap may be unavoidable.
Use your 4 exams and this Study Guide to study, but be aware that the format of the questions may change between multiple choice, fill-in, descriptive writing, problems etc. Especially with multiple choice, you must understand why the other choices were wrong. (The wording on the Final may make one of the previously wrong choices become the most correct one!). You should know the 'Big Eight' polyatomic ions and Short Set Solubility Rules (see the Study Guides)
Taking the Final Exam: **Bring your CALCULATOR and pencils/pen**
1. No extra/scratch paper, cell phones or any other material at your desk. Put all your materials up front (cell phones off). Spread out as best possible and be aware there will be different versions. Do not remove the staple or any pages of the exam. Occasionally check the front board for Time Remaining and any corrections to the exam.
2. Where a question asks for one answer, give only one answer! If you have extraneous answers and unused information, erase or cross it out. Put a BOX around your final answer. If I can’t read your answer or if your erasing is ambiguous it is considered wrong! If you need to practice, use a blank page of the exam and then put your one and only final answer in the space provided! (Otherwise I grade the first answer or drawing I see – usually that is not what you want! )
3. If you change your mind about a multiple choice, either completely erase the wrong ‘X’ or shade it out and draw an arrow pointing to the correct choice (à pointing to the correct ‘X’).
4. Please take ‘bathroom breaks’ before or after the exam time!

Ch. 11 Intermolecular forces – sections 1 – 7 (Heating Curve for Water)
- Know the three Intermolecular Forces: Dispersion, Dipol-Dipole, Hydrogen Bonding – their relative strength, their mechanism of attractions, and which molecules have them.
- How does the Ion-Dipole force work in mixtures?
- How are the physical properties melting point, boiling point, surface Tension, Viscosity, Vapor Pressure, ΔHvap , and ΔHfus related to strength of Intermolecular Forces?
- How do the ionic bonds in ionic compounds compare to strengths of the 3 IMFs?
- Do ionic bonds influence physical properties? (How can you tell if a compound is ionic?)
- What is a (dynamic) Equilibrium? (What’s dynamic about it?)
- What is Vapor Pressure? How does it relate to equilibrium?
- How is Vapor Pressure related to Boiling Point temperature?
- Explain how a liquid can evaporate at a temperature below the boiling point?
- If given ΔHvap , and ΔHfus for a substance, how could you find Heat of condensation and Heat of freezing?
- Be able to construct a Heating Curve for water showing where melting and boiling occur and where each of these terms would be used in calculations of heat: Heat Capacities of ice liquid water and steam {Csolid , Cliq , Cgas}, ΔHvap , and ΔHfus
- Be able to calculate either heat evolved or released when converting a given amount of water at a starting temperature to a final temperature where the changes involve temperature changes and state changes.
