Balancing Equations

We are working on predicting products of chemical reactions as well as balancing chemical equations. They should have a large amount of notes with examples in their notebooks. We will continue working on these all week. There are plenty of websites with tutorials if you need extra practice or a refresher.

Types of Chemical Reactions

We are covering 5 basic types. We are not concentrating on acid/base reactions

Types:
1) Synthesis

A + B --> AB

2) Decomposition

AB --> A + B

3) Single Replacement

A + BC --> AC + B

4) Double Displacement

AB + CD --> AD + BC

5) Combustion

Hydrocarbon (gas) + Oxygen (gas) --> Carbon Dioxide + Water

EOM Test Friday

The EOM Test Friday will cover ions (cations and anions), covalent and ionic bonding, balancing chemical reactions, naming reaction types, predicting reaction products, and acid/base reactions predicted based on hydrogen ion concentrations. We will also attempt to cover osmosis, diffusion, hyper/hypo/isotonic solutions.
