• properties of light (such as wavelength and frequency)
• bright line emission spectra for hydrogen (and other atoms)
• electronic transitions (ground state, excited states)
• quantum mechanical model
• quantum numbers
• atomic orbitals
• electron configuration and the filling of sublevels
• orbital diagrams
• electron arrangements in ions (including a special "first in, first out" rule that applies to transition metal cations, p. 150)
• periodic trends in atomic properties, including atomic radius, ionic radius, ionization energy, and electronegativity

Today in class students got answers to the Chapter 5 Practice Test. If you need to see a copy of these answers, you can look at this document.

The homework for Monday is to complete the Chapter 5 Test. Please e-mail me if you have any questions.

AP Chemistry Update

Today in class students reviewed some of the answers to the FRQ's related to Chapter 5 (Gases). If you need to see the answers to these FRQ's, you can look at this document. If you want to see a PowerPoint slide show that explains how the answers were obtained, you can click here to watch the slide show.

Students watched me perform a demonstration of how to calculate the molar mass of a volatile liquid. Even though I obtained rather poor results (i.e., 50% error!) from this experiment, it was still a decent thing to do. I wanted to emphasize that the molar mass of a gas is equal to (gRT)/(PV). You can see a YouTube video of another chemistry class doing this experiment by clicking here.

Students did a lab today involving the reaction of magnesium with hydrochloric acid to produce hydrogen gas. Based on the data collected from this experiment, students were able to calculate the value of the ideal gas law constant, R.

The homework for Friday's class is to complete the Chapter 5 Practice Test, which can be found here.

I will give out the take-home test for Chapter 5 on Friday, and it will be due on Monday.

E-mail me if you have any questions.

AP Chemistry Update

Today students were working on concepts from Chapter 5. After finishing up our discussion of the Chapter 5 Classwork from Friday's class, I explained the answers to the AP Multiple Choice Questions (MCQ's) related to Chapter 5. If you need to see the answers to these MCQ's you can look at this document.

These are some of the important concepts that were discussed in class today:

• If two gases are at the same temperature, then they have the same average kinetic energy.
• If two gases at the same temperature have different molar masses, the one that has a smaller molar mass has the largest average molecular speed.
• Gases will be most likely to deviate from ideal behavior at low temperatures and high pressures.
• The volume of one mole of gas at standard temperature and pressure (273 K, 1 atm) is 22.4 L.

The homework for Wednesday's class is to answer the Free Response Questions (FRQ's) related to chapter 5.

AP Chemistry Update

On Monday students had the opportunity to do a bit more practice with balancing redox equations. This corresponds to section 4.4 of Chapter 4 in the textbook. If you would like to see the PowerPoint notes that explain all of the example problems from the Chapter 4 Review Guide, you can click here.

If you would like to check your answers to all of the homework problems that have been assigned from Chapter 4 in the textbook, you can click here. Note that I have also included the answers to a few odd-numbered problems from the textbook that were NOT assigned for homework. So you should now have plenty of resources to guide you through the various concepts in Chapter 4.

On Monday we did not get a chance to discuss the AP MCQ related to Chapter 4. We will go over this soon.

The homework for Wednesday is to answer the Pre-Lab questions for the redox titration experiment. If you need a copy of these Pre-Lab questions, you can click here.

AP Chemistry Update

Today in class students (hopefully) increased their understanding of Chapter 4 material. The answers to Example #11 and Example #12 from the chapter 4 review guide were discussed. You can watch the PowerPoint Notes by clicking here. Just fast forward to the end to see Examples #11 and #12. Then we moved on to a discussion of Section 4.4 in the textbook (Oxidation-Reduction Reactions). Here are some important points about oxidation numbers:

• The oxidation number of an element in its elemental state is zero
• The oxidation number for a monoatomic ion is simply the charge on the ion
• The O.N. for alkali metals in compounds is +1
• The O.N. for alkaline earth metals in compounds is +2
• The O.N. for fluorine in compounds is -1
• The O.N. for oxygen in compounds is usually -2 (except peroxides or OF₂)
• The O.N. for hydrogen in compounds is usually +1 (except metal hydrides)
• In a binary covalent compound, the element that is more electronegative will have an O.N. equal to the charge it normally forms as a monoatomic ion
• The sum of the O.N. values is zero in a neutral chemical formula
• In a polyatomic ion, the sum of the O.N. values is equal to the charge on the ion

Now that you understand oxidation numbers, here is a procedure to help you balance a half-reaction:

• Step 1 = Balance the atoms of the element that is being oxidized or reduced
• Step 2 = Use electrons to balance the change in oxidation number ("OIL RIG" will remind you that oxidation is the loss of e^– and reduction is the gain of e^–)
• Step 3 = Use H⁺ ions (or OH^– ions) to balance the overall charge on both sides
• Step 4 = Use H₂O molecules to balance the H atoms and the O atoms

We did not get a chance to go over all of the homework problems in class today. I'll be talking more about that on Monday. The homework for Monday is to do the AP Multiple Choice Questions related to Chapter 4, which can be found here.

E-mail me with any questions. Have a good weekend.

AP Chemistry Update

The Homework for Friday is to answer questions 41-50 at the end of Chapter 4 from your textbook.

AP Chemistry Update

Today students learned more information about acid-base reactions. The following points were very important for writing net ionic equations:

• Strong acids (HCl, HBr, HI, HNO₃, H₂SO₄, HClO₃, HClO₄) should be written as H⁺
• Weak acids (HF, HC₂H₃O₂, HNO₂, HCHO₂, etc.) should be written as one formula, whatever its chemical formula happens to be
• Strong bases (NaOH, KOH, Ca(OH)₂, etc.) should be written as OH^–
• Weak bases (NH₃, CH₃NH₂, etc.) that are either ammonia or an amine should be written as one formula, whatever its chemical formula happens to be
• Net ionic equations should be balanced with respect to atom count and overall charge

If you are doing stoichiometry calculations related to acid-base reactions, it's a very good idea to start by writing the molecular equation. This will help you see a complete picture of what is going on in solution. If you only look at the net ionic equation, you might not see the correct molar ratio between two reacting species.

Consider the example above, based on problem #31 from the textbook. Barium hydroxide, Ba(OH)₂, reacts with nitric acid, HNO₃. The molecular equation shows you the 2-to-1 molar ratio between nitric acid and barium hydroxide. You need to use this ratio in your calculation. If you had only written the net ionic equation, you might have missed this point. The net ionic equation shows a 1-to-1 ratio between H⁺ ions and OH^– ions.

Answers to the Chapter 4 homework problems have been posted here. The homework for Wednesday is to answer the Pre-Lab Questions for the titration lab. E-mail me if you have questions.

AP Chemistry Update

Today students learned about some of the properties of acids and bases. Acids can be classified as either strong or weak. Strong acids are completely dissociated into ions. Weak acids are only partially dissociated into ions. In the pictures below, hydrochloric acid (HCl) is a strong acid that is completely dissociated into ions, whereas hydrofluoric acid (HF) is a weak acid that is only partially dissociated.

Bases can also be classified as strong or weak. Strong bases are typically ionic compounds that contain hydroxide (OH^-) ions. A weak base is a molecule or ion that accepts H⁺. One example of a weak base is ammonia (NH₃).

When acids and bases react together, the acid loses H⁺ and the base gains H⁺. Acid-base reactions can be written in the form of net ionic equations. You have already had some practice with writing net ionic equations for precipitation reactions. You will need to practice writing net ionic equations for acid-base reactions. This will require you to know if an acid or a base is strong or weak. Therefore, just like you had memorized solubility rules, you should memorize the strong acids (HCl, HBr, HI, HNO₃, H₂SO₄, HClO₃, and HClO₄).

The PowerPoint Notes for Chapter 4 have been updated to include Example #10 from your Chapter 4 Review Guide, which I discussed at the end of class today. This problem shows you four examples of net ionic equations.

Your homework for Monday is to answer the following questions from Chapter 4 in your textbook: 21 - 32 (on page 97).

E-mail me if you have questions. 

AP Chemistry Update

Today students reviewed their Chapter 4 homework in a way that encouraged collaboration and discussion in small groups. After class discussion, they turned in a worksheet that contained their answers to selected homework problems. Students also did a lab experiment today that was designed to help them strengthen their understanding of the solubility rules. Students mixed various solutions together and observed whether or not a precipitate would form. The homework for Friday is to write the net ionic equations for the precipitation reactions that occurred in the lab. A copy of the lab activity can be found here. Students should read ahead in Chapter 4 and be prepared to discuss acids and bases (Section 4.3).

MONDAY = Labor Day holiday
TUESDAY = Review for Unit 1 Test
WEDNESDAY = Unit 1 Test
THURSDAY = Introduction to Matter

FRIDAY = Lab experiment on Physical and Chemical Changes


Unfortunately many students did not perform well on the Unit 1 Test. Students will be given extra practice problems to reinforce concepts that they have not mastered yet. Students who did poorly on the Unit 1 Test should start coming in regularly during Mustang Morning. Students are strongly encouraged to improve their study habits, make flash cards, ask questions in class, and practice solving problems outside of class.

The PowerPoint file "Introduction to Matter" is now available on my web site. Click here to watch it again if you missed anything from the notes in class.

In AP Chemistry, students have completed the Chapters 1&2 Test and turned this in on Tuesday. They have been working on solving problems in Chapter 3, which deals with mass and mole relationships (stoichiometry). Students should become familiar with the techniques for solving these types of problems. Many examples can be found in the textbook. Answers have been posted to the FRQ and MCQ problems and these documents can be found in this folder on my web site. On Monday we will do a lab experiment involving formulas for hydrates and calculating empirical formulas from mass data. The homework for Monday is to answer the pre-lab questions that were given out at the end of class on Friday.

Chemistry Update

Here is a brief look back at the week of August 29 - Sept 2.

AP Chemistry

I have completed our discussion of Chapters 1 and 2, and you should be working on your take-home test over the Labor Day weekend. E-mail me with questions. I expect to receive your completed test on the morning of Tuesday, September 6th.
At this point we have basically completed our discussion of Chapter 3 concepts, including mass-mole relationships and stoichiometry. I'll give you Chapter 3 practice problems on Wednesday and the Chapter 3 test will be coming soon.

Advanced Chemistry
Here is a summary of the activities from this week:
On Monday, we finished up the laboratory involving the density of colored liquids. We also finished reviewing the packet entitled "Math Concepts Used in Chemistry." Then I gave a Math Assessment, which hopefully gave everyone a good idea of whether or not they should start coming to Mustang Morning for some math assistance.

 On Tuesday, we looked at SOL Chemistry questions in the Scientific Investigation strand. If students would like to practice answering Chemistry SOL questions, they can visit the Jefferson Lab website and select Chemistry. 

When prompted for more options, you can select the "Scientific Investigation" strand.

On Tuesday students started taking notes from a PowerPoint slide show presentation entitled "Scientific Notation and Dimensional Analysis." This PowerPoint slide show can be viewed on my website by clicking here, and the handout for these notes can be found by clicking here.

On Wednesday, I gave students the opportunity to practice conversion problems using dimensional analysis. I explained that a conversion factor is a ratio that allows you to convert from one unit to another. Some problems have only one step, but other problems require 2 or 3 conversion factors. It is very important to write down the units during every step, so that you can clearly see how to cancel them out.

On Thursday, we did a measuring activity using small wooden or plastic blocks. The students learned that when a measurement is made with a ruler, the final digit is an estimated digit. This final digit can be a "zero" if the measurement is exactly on the line.We also discussed the concepts of precision, accuracy, significant figures, and graphing. The PowerPoint slide show for these notes can be found on my website by clicking here, and the handout for these notes can be found by clicking here.

On Friday, we did a lab activity using rubber stoppers. Students used the technique of water displacement to calculate the volume of the stoppers. Then they plotted their mass and volume data on a graph, as a way of determining the density. When mass is on the y-axis and volume is on the x-axis, the slope of the line equals density.

HOMEWORK: Students should study their notes completely. Then they should complete the Unit 1 Practice Test, which can be found by clicking here. This practice test will be reviewed in class on Tuesday. The Unit 1 Test will be on Wednesday. E-mail me with any questions. When you come to class on Tuesday, you should be well-rested and ready to learn! Have a great weekend.

AP Chemistry Students - Hydrocarbons

I know that we have only had two classes so far, but I thought that some of you might have been confused about the topic of hydrocarbons. For example, how does one write all of the structural formulas for a given molecular formula? This video should help you out if you were confused about the "Exploring Structural Isomers" worksheet from  Friday's class.

Welcome to Chemistry

Here is a summary of our activities from the first two days of school:

AP Chemistry:
After a brief introduction and overview, I began to review material from Chapter 1. The homework assignment was to read Chapters 1 and 2, which represents basic information about chemistry. I also handed out two pieces of paper, which included sample questions from VA SOL tests in Chemistry and sample questions from AP Chemistry tests. The purpose of these two papers was to give students a general feeling of "That was then...and this is now." Please see me for extra help if you need to review anything from Chemistry I.

Advanced Chemistry
On Wednesday I introduced students to the concepts of laboratory safety, and the homework was to complete a Lab Safety Quiz. I also introduced some math concepts that are relevant to chemistry. We talked about the procedure for how to convert a number into scientific notation. We also discussed how to do multiplication and division with numbers in scientific notation.

On Thursday (today) we did a short "do now" problem that involved algebraic skills in rearranging variables in an equation. We started with an equation "PV = nRT." Students were rearranging this equation to isolate each one of the five letters. We did more work on math concepts relevant to chemistry. We discussed conversion factors, which are ratios that are used to convert from one unit to another. For example, you can use the density of an object to convert from mL to g (or from g to mL). We did a brief lab experiment in which students used a plastic straw to compare the relative density of three colored solutions. The homework assignment was to do the following. Write a procedure for how to determine the density of a liquid. Tomorrow we will be giving you a math assessment, so review your math skills.

Don't forget to bring a 3-ring binder to class, with paper and pencils. Bring a calculator to chemistry class every day!

THE ATOM (Unit 3)

On Monday we explored the topic of Atomic History, as I made "virtual" interviews with Democritus, Antoine Lavoisier, John Dalton, J.J. Thomson, and Ernest Rutherford. You should be familiar with these five people and how their work influenced our understanding of the atom. You should also be familiar with terms like atomos, law of conservation of mass, cathode ray tube, plum pudding model, alpha particles, and the gold foil experiment (alpha scattering experiment) which led Rutherford to the idea of a nuclear model for the atom.

On Tuesday we explored the properties of protons, electrons, and neutrons. The atomic number is the number of protons, which is unique for each element on the periodic table. The mass number is equal to the sum of the protons and neutrons. A pair of isotopes are defined as two atoms that have the same number of protons but different numbers of neutrons. An ion is an atom that has either lost electrons (to form a positive ion) or has gained electrons (to form a negative ion).

Today we explored the idea of a weighted average. In our "Isotopes of Beanium" activity, we saw that when the relative abundance of two isotopes is NOT 50%-50%, you need to calculate the average using decimals, like this calculation, for example with chlorine:

(35) x (0.75) + (37) x (0.25) = 35.5

Tomorrow we will explore radioactivity and half-life. There will be a practice test review tomorrow and a Unit 3 Test planned for Friday. Keep studying!!
