Notice on page 594, there is an example of a reaction between NaCl and
AgNO3 to produce NaNO3 and AgCl. Does the book describe this reaction as
a redox reaction? If not, look and see why, Complete question number 3 on the
following page 595. Simply type in the oxidation numbers for each element in order they are
listed and they indicate if the reaction is a redox reaction. (Complete a-e. You will
need to be able to determine oxidation reactions with ease. The sooner you start the sooner you
will get to that point. Make it happen. )

Balancing oxidation reduction reactions is very important and is not sufficient
to just be familiar with it. You need to master this process so that during a multiple choice
problem set you can fly through them. This book provides one way to balance these
reaction. This method works but I like a different method better. The method given at
this web site shows how I will be explaining it in class. Go to this site and study this
method.
