Chemistry Karate Practice!

 This is the  Chemistry practice sheet Here is the Chemistry practice sheet key.

Do the work on this practice sheet on your own piece of paper up to page 11.  If you finish, you can continue your practice.   Take breaks as you need to! This is hard work!

 10 marks for completing this. 

later,  is an activity next week called " Chemistry Karate"  where your chemistry skills will be respectfully assessed by myself and by peers and you will demonstrate your level of chemistry karate belt.  The goal is to move up one belt, not for everyone to be a black belt ! 

 

TYPES OF REACTIONS

TEACHING NOTES: First lets review the main types of reactions: 

notes on types of reactions

Study Guide  and answer key below

 answer key to your chapter 6 worksheet

LESSON: Chemical reactions may be categorized as follows : 

1.     Synthesis

2.     Decomposition

3.     Single replacement

4.     Double replacement

5.     Combustion

       Cellular Respiration

6.     Oxidation of metals

Synthesis reaction:

element     +   element    -->    compound

Decomposition reaction:

Compound    -->   element     +     element

Or

Compound --> smaller compound    +   element

DOUBLE REPLACEMENT


single replacement

IN ADDITION TO THE FOUR TYPES ABOVE, THERE ARE ALSO THREE MORE KINDS of reaction TO KNOW: 

Combustion:  combustion may happen to any *organic compound* meaning any compound made of carbon, hydrogen and/or oxygen...

Carbon based compound+ oxygen --> carbon dioxide + water

+ heat and light energy

Cell respiration looks like combustion,

BUT IT IS NOT. YOUR CELLS ARE NOT COMBUSTING.  The carbon based compound in this case is glucose, a simple sugar.

Glucose +   oxygen -->  carbon dioxide + water + energy for cell

Oxidation reaction

Metal +  oxygen   -->   metal oxide

ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS

In summary....

Calcium lab report

    

Lab Jounral assignment includes the following labs:

Assignment:   Write up our lab on Calcium and water. FORMAT:  paper write up or word doc or pdf or powerpoint 

image by Katelyn M

 Your lab must include the following

1.  Your First and Last name 

2. Purpose of lab:  The purpose of the lab is to find out what happens when you add calcium to water. PART I  Describe the teacher demo that preceded this lab. 

PART II DESCRIBE THE STUDENT EXPERIMENT IN DETAIL 

3.a Materials: write a complete list of materials that we used 

b.  Safety:  list the safety precautions for this lab

4. Procedure: Draw a cartoon to describe the step by step procedure  that is so well written that another person could read it and replicate your actions exactly. You may also upload pics demonstrating your procedure. 

A. PROCEDURE WITH TEST TUBE AND BEAKER

B  PROCEDURE WITH BEAKER AND SOAP

5.  What is the question we are trying to answer?  For example there were two possible gases that came out of this reaction.  What gases were they? What are the three BALANCED EQUATIONS that were possible outcomes of this lab?

6. Results:  Describe in detail what happened after you did the procedure.  Include any photos you took.  How did you know you made the gas, which gas?  

7.  What was the white stuff?  How did you test for the identity of the white stuff? 

8. Write your conclusion in paragraph form.  


EVALUATION   IS OUT OF 25 IN TOTAL

5
presentation is out of 5.  for 5/5 it is typed  with illustrations or photos and handed in electronically or on paper

     for 4/5 it is pretty good but there are a few spelling mistakes.  for 0-3 out of 5 it is in pencil or messy.  I prefer this to be printed

10
Clear writing is out of 10.  for 9/10 or 10/10, it is written with no English mistakes and it clearly communicates each part of the lab report.    7-8/10  it is very well written     for 5-6/10 some parts are not so clear and the reader must guess what you are trying to say.  0-4/10, it is minimally communicating what happened

10
Paragraphs are insightful and your observations are well done. this is out of 10.
             9-10/10,   your observations and conclusions are well written and logical.  It is brilliant
              7-8/10   your observations and conclusions are very well done
               5-6   your conclusions don't really logically follow from your results
                0-4   your conclusions are not relating to your results at all
