Day 153

Hi class,

Don't forget to comment below before your final tomorrow. Hannah Gray, please email me as soon as possible.

Here is a link to the Review Sheet, Practice Test and the Practice Test Key. The correct answers are in boldface. Remember, there is an optional 500-word essay on polymers due the day of the final. Also, you will not receive a report card if you do not return your chemistry textbook. Your Edline grades will be updated tonight with the additional 4 percentage points. If you have any questions, you can ask me via email. Below, I am compiling a list of typos, so please email me if you find any.

Review Sheet Typos

Day 152

Hi class,

Don't forget to comment below by class tomorrow.

Workspaces is undergoing maintenance today, so I have shared the finals study guide with all of you through Google Drive. I will hand-out hard copies of the study guide tomorrow as well as a sheet with equations, constants, etc. that will be identical to the one you will receive for the final exam. I will also give you a practice test with examples of the types of problems you will see on the final. I will share the practice test on Google Drive when its is complete.

To prepare for the final exam, you simply need to understand the concepts on the study guide and be able to apply these concepts to the practice problems.

Day 142

Hi class,

You don't need to comment on this blog post. For those students in fifth period, I have summarized the last three slides below for the quiz tomorrow.

Surface Tension

• Surface tension is the energy required to increase the surface area of a liquid by a certain amount
• Stronger IMF-->greater surface tension
• Why?: stronger net downward force on surface particles
• Surfactants decrease the surface area of water by disrupting the hydrogen bonds between water molecules
• Examples: soaps, detergents

Cohesion and Adhesion

• Cohesion describes the force of attraction between identical molecules
• Adhesion describes the force of attraction between different molecules
• Some liquids for a meniscus when placed in a narrow container
• Water forms a "smiley" meniscus in a glass tube because the adhesive forces between the water and the glass are stronger than the cohesive forces between the water molecules
• Mercury forms a "frowny" meniscus in a glass tube because the cohesive forces between the mercury molecules are greater than the adhesive forces between the mercury and the glass
• Capillary action is the upward movement of liquids in extremely narrow tubes
• how?: The liquid climbs the walls of the tube due to adhesive forces, which causes the surface area of the liquid to increase. The cohesive forces cause the rest of the liquid molecules to move upward to decrease the surface area. This continues as long as gravity allows.

Solids

• According to kinetic-molecular theory, particles in solids vibrate around fixed locations due to strong IMF
• Most solids are more dense than more liquids
• Why?: stronger IMF in solids than liquids-->particles are closer together/take less space-->greater density

Day 140

Hi class,

Don't forget to comment below by 8 am on Friday.

The quiz on chapter 12 will be administered during class on Friday. If you missed class this week, you may take the quiz on Monday, but you will miss the first lecture on gas laws.

Chapter 9 (Equations) Quiz
Chapter 10 (Mole) Quiz

Day 114

Hi class,

Comment below by 8 am on Monday.

As you know, the nine weeks exam has been moved to this Tuesday. The exam will still contribute to your Quarter 3 grades. Since the exam is worth 100 points, this test can really help or hurt your grade. You are allowed to bring a cheat sheet, which I will discuss in further detail on Monday. You can also ask me any questions at anytime via email or in class on Monday.

If you need more practice on naming and writing formulas, check the last blog post. If you need more practice on Lewis structures rework the Lewis Structures Worksheet, but this time make sure to draw the BEST Lewis structure (by calculating formal charges). If you need more practice on equations, rework the Equations Worksheet. If you need more practice on the Mole, rework the example problems from lecture and the homework problems.

Day 111

Hi class,

First of all, all blog comments this week will be counted as bonus participation points rather than ordinary participation points. Also, you can comment on all the blog posts this week anytime before 8 am this Saturday.

Hopefully, you watched the review lecture on nomenclature during class today. If you would like me to share the video with you on google drive, let me know via email. If you have any questions about nomenclature, try to email me with your questions by Thursday evening.

If you're struggling with nomenclature, rework the worksheets on nomenclature. If you want more practice, here is another MixedNamingWorksheet. Here are the MixedNamingWorksheetAnswers.

Day 110

Hi class,

Don't forget to comment below by 8 am tomorrow.

As a reminder, you can replace the grade on the last quiz with your grade on the equations section of your nine weeks exam. The nine weeks exam will cover chapters 8, 9, and 10.

The test on chapter 10 will be administered during class tomorrow. To prepare for the test, rework the example problems from lecture and the homework problems. If you're short on time, just read the lecture notes and answer the lecture problems. If you have time, answer the lecture problems, then try to answer the homework problems faster and without looking at your notes.

If you have any questions, you can email me anytime before 12 am. If you are concerned that your question can't be answered through email, ask me anyway. I can figure out a way to answer your question electronically.

If you missed class this week, you may take the test after Spring Break. I recommend taking the test tomorrow if at all possible, so you don't have to study over the break.
