Notes on Reactions

 answer key to your chapter 6 worksheet

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

A 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....

Chemistry Karate

 We play Chemistry Karate" today  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 ! 

 

LEGO BALANCING ACT

 We practiced balancing equations using lego. make sure you finish this and UPLOAD PICS on TEAMS

Remember you need to have also finished these worksheets.

Recall that worksheet  Chemistry practice sheet and the  Chemistry practice sheet key. This was given for homework and you will be tested on this soon.

Tuesday and Wednesday lesson for Oct 11,12

Tuesday:

Take the time to work on the Participation TEAMS assignment which I posted.  If you finish, just use the time as a study block

  Read the following notes

Assignment : Do the study questions, put your name on it and photograph it.   Answer key is here. 

Wednesday Thursday Friday worksheets

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

If you finish,  use this time as a study block

Bohr Diagram and Lewis Diagram

     

You will practice drawing Bohr Diagrams and Lewis diagrams.   You should work through this Study guide on the same topic  and the Answer key   

Your teacher will make a list of your names from the attendance roster and give you 5 marks for completing this work
