Overview
Entire course taught by working example problems.
Every problem worked step-by-step.
We begin with easier topics such as Molar Mass, Reactions, etc.
This builds confidence in the student!
In this course, we begin to discuss applications of chemical reactions to a very important class of chemistry problems - reactions in aqueous solutions. First, we discuss aqueous solutions and ion concentrations and teach by worked example problems how to calculation ion concentrations in solution.
Next, we introduce the concept of an acid and a base, how to classify acids and bases, and why they are important in chemistry. We discuss how acids and bases react, what they produce, and how to perform calculations for titration problems with acids and bases.
Numerous example problems are worked step by step to give the student practice and confidence with acid-base reactions.
Next, we teach how to predict if a substance will be soluble in water or not based on its chemical formula. This is important for the next topic, which is precipitation reactions. In this type of reaction, the student will predict which of the products will be insoluble and thus form a precipitate. We'll cover net ionic equations for aqueous solutions and give the students many opportunities to practice.
All concepts are taught by fully worked example problems to teach students the most effective methods to solve chemistry problems.

Description
Chemistry problems are difficult for many students because there are usually numerous steps for every problem, and every topic in the course builds on the previous topic. If the student has problems with an earlier topic, then all topics that follow will seem harder than they really are.
This course takes every topic one step at a time and teaches the student chemistry by working problems. In this way, the student will build confidence early on through repetition and build exam taking skills at the same time.
This course begins with a discussion of the molecular mass of a compound and how it relates to the formula mass. We then introduce Avogadro's number and the concept of the mole as a measure of the quantity of a substance. Numerous example problems are illustrated to show the student how to perform calculations involving the mole.
We then discuss the concept of the percent mass of an element in a compound, followed by the central topic of the chemical reaction and balancing chemical reactions. We continue by working with reaction stoichiometry, which allows us to use the reaction to calculate how much of product we will produce as the reaction proceeds to completion. A very powerful technique is presented here that will make all chemical calculations very easy for the remainder of the course.
We conclude with detailed lessons that involve the limiting reactant, percent yield, molar concentration, and solution stoichiometry where our reaction will involve solutions.
