"WHAT'S IN A NAME?"

(REVIEW)

Introduction

The purpose of this lesson is to review all the things that can be figured out from the name of the chemical, at least all of the things that you have worked with so far in this course. This review will cover many (but not all) of the things that you have studied in this course.

 

Lesson Organization

As usual, the objectives and assignments for this lesson are given in the preliminary information section (as well as in your workbook).

The first section of this lesson provides an overview of the several types of names for chemical compounds and how to determine the formula of a compound using the information contained in the name. Once the formula of a compound has been determined, many other things can figured from that. The remaining sections of the lesson review how to determine those things.

In your workbook there are a number of objectives, each related to figuring something out from the names of compounds. Each of the exercises in your workbook is numbered to match the objective to which it pertains. The first seven (1-7) deal with identifying types of chemicals, the next two (8-9) deal with formulas and composition, the next two (10-11) deal with balanced equations, the next three (12-14) deal with weight relationships in chemical reactions, and the last three (15-17) deal with molecular properties.

Each of these objectives has its own page within this web. On each of those pages the objective is stated and briefly explained, the exercises from the workbook are listed, usually a few of those exercises are worked out for you to look at, then the correct answers for those exercises are given.

There are a number of approaches to studying this lesson that can be taken depending on how much and what kind of review you need. The simplest approach to reviewing this material would be to use your workbook and read each objective in turn, practice that task by doing the corresponding exercise, then check your answers on the appropriate web page.

If you need help getting started on a particular task, check the worked-out examples on the appropriate web page. Then try the other exercises. If the worked-out examples aren't enough help, check with an instructor in the lab or on-line for additional help. You can also refer back to the lesson where that topic was originally presented.

There is also an extra exercise (Ex. 18), which combines quite a few different kinds of things, and goes off on a few tangents. It will provide additional challenges for you if you want to try that.
