Heating/Cooling Curve Tutorial

Here is a link to a pretty good tutorial on heating curves and the math used to solve the problems

Class Notes Update and Practice Problems

I put up a link to some example problems that show the process to solving problems associated with calorimetry and specific heat.

As for extra practice problems, here is a link to those as well.

Calorimetry Simulator

Use the above website for class today.  Goal of class is to Identify Metals X and Y

pH Quiz Answer Key

Here is my answer key for the pH quiz.

NOTE:  the majority of you who missed 1 or 2 pts on the #4b did not include the 2:1 mole ratio for the Chloric Acid:Barium Hydroxide.

Acid/Base Virtual Lab

BIOCHEM - Sorry for the delay.  I now understand "internet issues" can be a viable excuse.  I am finally able to upload info to the blog.

Here is the virtual lab.  If you have some time today to do it, awesome.  If not, please spend class time tomorrow working on it.  My goal is that it reinforces the concepts of weak/strong acids and bases involving strength vs. concentration.  You may consult your notes, a text on the bookshelf in the back of the room or the google.  However, just looking up the answers online will not reinforce the concepts the way the simulation would.

Please download/print the following two documents:

Acid/Base Investigation 1

Acid/Base Investigation 2

The simulation is directly to the right on the blog.  In the lower right hand corner is a menu box that allows you to make it full screen.

You are required to due Investigation 1.  Investigation 2 will be extra credit.  The extra credit, if done properly, will drop your lowest quiz score for the 2nd trimester.

You have two methods to turn this in.  One, print it, fill it out and make sure it is on my desk in my office before the end of the day tomorrow.  Two, do the same thing, but scan/email it me if you are worried it will get lost in the sea of papers on my desk.  Again, by the end of the school day tomorrow.

Introductory Information regarding Acids, Bases and pH Scale

Lab Questions and Quiz Reminder

Here is the link to the lab questions.  They are due at the START OF CLASS on Monday.  Use your data, your knowledge of chemistry, your notes, whatever helps, to answer the questions.  If you need more room, use a separate shape of paper.


Also, reminder that there will be a short quiz on:

Predicting products/balancing Neutralization Reactions

Naming/Writing Formulas for Acids and Bases

Update to ClassNotes

New Acid/Base Documents have been added to the ClassNotes page.

Review Problems Answer Key

Here is the Answer Key.  There is also a blank review sheet in case you left yours at home.  The answer key starts with the blank review guide, so scroll down to find my hand written notes on the answers.

Lab Write-Up Outline

Lab Write-Up

For your FORMAL Lab Write-Up you need the following sections.  Next to the section is a description of the information that goes in it and relative length of each section.

Title: - Should be scientific and not "catchy."  (i.e "Investigating the Effects of Caffeine on Blood Pressure" - - - Not "Does Java Give You the Jitters?")

Introduction:  Usually about 1 page.  It should highlight the scientific concepts needed to understand the lab.  For this lab I would focus on the relationship between energy and EM radiation type, explanation of SPF, and the difference between the active ingredients.  This info should come from your research and needs to be cited.

Materials List:  A list of the materials, chemicals, equipment, etc. you used.

Procedure:  A step-by-step, specific list of the steps you took to collect the data.

Data:  Tables that organize your data.  Highlight UNITS.  Tables should have descriptive titles, especially when more than one is used.  Example:  Blood pressure readings for individuals who consumed varying amounts of caffeine.

Calculations:  Examples of any calculation you used (i.e. averages, percentages, differences, etc.)  As we do more complex labs with different calculation specific to chemistry, this section will change.

Results:  Tables that organize the answers to your calculations.  This section should highlight comparisons to your variables, but focus on the averages and not the individual trial data.

Discussion:  THIS IS NEW.  This section explains to the reader what your results mean.  Which sunscreen was better?  How do you know?  Point out specific results and explain how they lead you to make these decisions.  Is the difference a lot or a little.  This usually takes about 1 or 2 paragraphs.  The next part of the discussion educates the reader on what might have gone wrong during your lab.  This is called sources of error.   Again about a paragraph.  Lastly, the discussion ends with a suggestion to fix the sources of error and/or improve the lab if it was repeated.

Class Notes Page

There is a new Class Notes Page that will contain powerpoints/videos/websites used in class for your review.
