Metal oxides are generally insoluble in water and react with water to form hydroxides in synthesis reactions.  Non-metal oxides are soluble in water and react with water to form acids.
We began to design an experiment in partners to demonstrate one single displacement and one double displacement reaction.  The instructions are in the document called "expt design" and the rubric is in "chem rxn demo rubric", both on the unit 2 page of this website.
Homework:  study for the unit test - see yesterday's homework for review questions

Your unit test will be Friday, Oct. 22, 2010.  Combustion reactions are reactions that have oxygen as one reactant.  Read p.123-124 including margins. 
Homework:  Answer p.124 #17-20 and complete handout on balancing and types of reactions
Test Review:  back of handout (found on Unit 2 page of site as "review.doc") and p.149-150 #1-6, 8-10, 14; p.156 #41.

We did the experiment on p.136-137 of the text. 
Homework:  Answer the following discussion questions and write a conclusion.
1.  How do you know when a double displacement reaction occurs?
2.  Did your observations agree with your hypothesis?  If not, specify the reaction.  Can you think of an explanation?

Double displacement reactions either produce precipitates, produce a gas, or are neutralization reactions.  We use the solubility table on p.334 to determine whether a precipitate forms.  Refer to p.132-135, 334 in text for help with these concepts.
Homework:  p.134-135 #25-28

A metal reacts with a compound or a halogen reacts with a compound.  Some combinations do not react.  You must consult the activity series, p.130, to determine whether a reaction occurs.  Refer to p.126, 127, 130, 131 in the text for help.
Homework:  Answer p.127 #21; p.131 #22-24

The four major types of reactions are synthesis, decomposition, single displacement, and double displacement.  Look in the text on p.119-122, 126-127,132, 135.
Homework:  Answer p.122 #10-12; p.123 #15, 16; p.125#5, 6.

We reviewed the 5 signs of chemical change and went through how to test gas products of a reaction to see if they are oxygen, carbon dioxide, water vapour or hydrogen.  Remember that your pamphlet describing the effects of your hazardous substance on the environment is due on Friday.
Homework:  p.29-30 #1, 3, 13

We reviewed balancing equations from Grade 10.  Refer to your text, p.112-116 for help, especially the steps to follow on p.116.
Homework:  p.113 #3, 4;  p.116 #5, 6;  p.117 #7; p.118 #9, 4, 5

Remember that you must complete Part 2 of the Hazardous Materials Assignment for Friday, October 8, 2010.

We had a quiz on nomenclature of compounds, then worked on review for the unit test.  The review and expectations for the unit are found in the document called "review questions" on the unit 1 page of the website.  We looked at a table of properties of compounds and determined what each person's hazardous chemical was. 
Homework:  prepare for test on Monday;  complete Part 2 of the Hazardous Materials Assignment for Friday, October 8, 2010.
