Electrochemistry and Thermodynamics
April 30th - May 4th
We will quickly visit the electrochemical cells on April 30th and May 1st. Both galvanic (voltaic) and electrolytic cells will be demonstrated. Then we will learn about the interrelationship of enthalpy, entropy, and Gibbs free energy. These thermodynamic concepts help scientists determine whether a reaction will occur. The second law of thermodynamics will be discussed.

Acids and Bases
March 29th to April 11th
We will continue with chemical equilibrium and how it applies to acid/base chemistry. Acids and bases are common materials found in nature and in industry. Many reactions would not occur without specific acidic or basic conditions. The reason we have stomach acid is so the enzymes can work to digest our food.

Chemical Equilibrium
March 22th - March 29th
We will begin our three chapter long study of chemical equilibria. The concept of chemical equilibria will explain percent yield, will compare and contrast reactions that go to "completion" and those that are easily reversed. Le Chatlier's Principle helps us predict what happens to a chemical system when a stress is applied - especially important in climate studies.

Chemical Kinetics
March 8th to March 20th
Chemical kinetics involves determining the rates of reactions (with or without catalysts). Reaction kinetics can only be determined experimentally. Our bodies use enzymes (catalysts) to speed up the digestion of our foods. Many industrial chemical production facilities need catalysts to increase rates of reactions and product yield. This will be a "quick" study (pun intended).

Properties of Solutions
February 27th - March 7th
This unit investigates homogeneous mixtures and their properties. Solubility of solids and gases, miscibility of liquids will be explained and tested. We will learn that adding a salt to water increases the boiling point and decreases the freezing points of the water. Applications are endless in that the world is made of more solutions and mixtures than pure substances. The physical properties of the solutions in always concentration dependent and composition dependent. We will make ICE CREAM and play with Coke and Mentos. How cool is that?

Chemical Bonds: General Concepts
Chapter 8
This unit is extremely important in understanding molecules, stereo-chemistry, and reactions. Stereo-chemistry is the study of how the three-dimensional arrangement of atoms in a molecule influences the chemical and physical properties of that molecule. There are important biochemical applications of stereo-chemistry. There may be a more modern word but I like the sound of it. Good websites for visualizing molecular geometry

Covalent Bonding: Orbitals
Chapter 9 - October 19th -26th
This chapter continues with Unit 3. It goes into greater depth with orbitals, hybridization, and molecular orbitals. Students should begin to see the complexity of sharing electrons within molecules. The content is applicable to the development of medicinal drugs and gene therapy. Hybridization of Atomic Orbitals Model
This a a great simulation of the hybridization of atomic orbitals in the formation of molecules. MHHE

Stoichiometry
Chapter 3 - October 28th - November 17th
In this chapter, we will review stoichiometry of compounds and reactions. This content applies to all future content areas and it is absolutely necessary to master its content to succeed in subsequent lessons. Topics will include empirical and molecular formulas, mole ratios, formula mass, percent yield, and limiting reactants. Applications are limitless.
We will do our first AP Labs in this unit - various Gravimetric Analysis experiments

Report for the Metal Carbonate Lab (click to see the instructions)
The report should include the following sections: title, purpose, data table (measurements only, no calculations), calculations (show work) - include percent error in the calculations, and analysis.
The analysis is the most important part of the lab. Discuss your results, how you determined the answer with the data collected, justify your work using known stoichiometric concepts, and explain your error appropriately. Due two days after the completion of the lab. |
Composition of a Mixture Lab
The report should include all data, calculations, and results as well as an analysis of your results. The analysis should include a justification of your calculations using stoichiometric principles and an appropriate error discussion. Please do not include purpose, procedure, or materials. Due by Monday, November 28th.

Reactions in Solution - Chapter 4
Solutions
Chapter 4 Sections 1 - 3
November 18 - 30 This is an extension of Chapter 3 where we begin to investigate reactions in solutions. In the first part of the chapter, we will discuss various ways to express solution concentration. We work with, drink, or make solutions everyday.

Predicting Products of Reactions
December 14th - 21st
We will use a different text book for this unit. It is more comprehensive than the Zumdahl book we are using. In this section, we will go over reactions and the typical products formed. Th AP Chemistry test always requires that students be able to do this. Students will practice using past test questions. Lesson Plan |
Types of Chemical Reactions
Chapter 4 Sections 4 - 10
December 1 - 13. The rest of Chapter 4 focuses on recognizing what is happening in a reaction, being able to predict the outcome and write a balanced equation for that reaction. Your body is an incredible chemical factory. Redox titration Lab Reactions PowerPoint Study Guide

Gas Laws
January 3rd - January 17th
This unit will include all the gas laws, kinetic molecular theory, stoichiometry, and deviation from ideal behavior. There will be one lab and a few demonstrations. The lab will use the ideal gas laws to predict the molar mass of a gas. Gas laws have widespread applications including atmospheric chemistry, hydrothermal venting (geysers), and volcanic eruptions. This unit will be followed by a midterm exam on stoichiometry. Lesson PlansHelpful Handouts, Videos, and Web PagesLab Report Instructions_A Gaseous Tale Project - on Project page

Liquids and Solids
February 7th - February 17th
This unit covers the properties of solids and liquids - the other states of matter. We will answer the question "What makes a solid a solid and what makes a liquid a liquid?" The answer lies in the bonding and intermolecular forces. The physical reality of solids and liquids is EXTREMELY important to our planet and life in general.

Thermochemistry
January 25th - February 6th
In this unit we are introduced to the concept of enthalpy, the measurements of heats of reaction, heat of formation. The evolution and absorption of heat is present in everyday life. Our bodies maintain a temperature well above ambient temperature, we cook our food using heat, climate change is a "hot" topic at the moment. Knowledge of thermochemistry can give anyone a perspective on heat. |
