Activity Series

Today we used single replacement reactions to determine the order of reactivity of metals.

There is a test next time.  Be sure to study.

Here's what you need to be able to do:

1. Name and write compounds.  Don't forget polyatomic ions.
2. Write equations.
3. Balance equations.
4. Recognize equation types

That's it.

Oh, and there's a midterm next week.  Be sure to study for that.  If it was on a previous exam, it's fair game for the midterm.  I have put blank copies of all previous exams up on the website under "Chemistry Files".

Homework:

  Study

Exothermic/Endothermic Lab

Great job on the lab today.  Great job cleaning up as well.  Keep up the good work.

We're going to practice balancing equations for one more day and then take the test.  Please start studying for the midterm.  If it was a concept covered on a previous exam, it is likely to be on the midterm.  I will make sure that all of your tests are returned to you next week.


Homework:

1. Do: Finish Lab Report
2. Do: Practice balancing equations

Types of Reactions

We went over the 5 types of chemical reactions:

1. Synthesis
2. Decomposition
3. Single replacement
4. Double replacement
5. Combustion

Homework:

1. Practice balancing equations
2. Read: Endothermic/Exothermic Reactions
3. Do: Start lab report (Purpose, materials, procedures)

Chemical Equations

Regarding the previous exam:

1. Corrections are due two class days from now before school.
2. You can earn back half of the points that were missed.
3. Make sure you follow the correction guidelines posted on the website.
4. Hydrocarbons will not be on the midterm, but everything else, including VSEPR, will be.

Writing Equations:

1. States of matter are shown.
2. Make sure that everything on the left and the right are balanced.

Homework:

1. Watch: Reaction types
2. Do: WSQ-Types
3. Optional, but recommended: Balancing Equations Worksheet
