introduction
There are millions of chemical compounds, and each one can undergo many different kinds of chemical change. It would be impossible to learn all these reactions. Fortunetely, chemists looked at many different reactions and found that some had common characteristics.
Five common types of reactions are:
Formation
Decomposition
Hydrocarbon combustion
Single Replacement
Double Replacement.
Read and make detailed notes from pages 91-106

Read pages 91 - 101 (skip p. 98-99), and define each type of reaction in your notes and include two examples of each reaction.
As you read through each type, make sure you carefully go through each of the Example Problems and try the Practice Problems (in your notes)
In the Skill Practice – Decomposition and Single Replacement Reactions on page 97, do questions #1-4
predicting products for reactions
predicting products for reactions
Remember that ionic compounds steal electrons and molecular compounds share electrons
In order to know the products of the reaction, we need to know the number of valence electrons the atom has and how many bonds it can form
Look at the Periodic Table of Elements!
Examples:
Na(s) + Cl2(g)
KOH(s) + BaF2(s)

Predicting the Products of Chemical Reactions
Carefully go over the Example Problem A3.10 on page 102-103. Attempt Practice Problem #10 on page 102. If you experience difficulty with this problem, make certain you ask a teacher for assistance.
Go through Example Problem A3.11, then attempt Practice Problem #11-12 on page 105. Again, if this is too difficult ask a teacher for assistance.
