Class of: 25-Feb-2016.

Today we covered started Chapter 9: Investigating Chemical Reactions. We began with Section 9.1: Describing Chemical Reactions (p. 231).

We also had a quiz today on Chapter 8!

Learning Objectives:

• Students will be able to describe what a chemical reaction is and name reactants and products.
• Students will be able to demonstrate understanding of the conservation of mass and atoms that takes place within a chemical reaction.

Please work through the following review problems:

Class of: 24-Feb-2016.

Today we will be doing a lab on acids and bases! Check out the report and marking check-list here: Sci 10 8.L Checklist [FIXED]

You also have a quiz on Thursday, 25 Feb!

You will need to know how ions are released in solution from an ionic compound. You will need to know how to draw Lewis diagrams for single atoms and for covalent compounds. You will need to draw structural formulas for simple organic compounds. You will also need to know how to classify compounds as organic or not, specifically which definitions you use.

Class of: 23-Feb-2016.

Today we began an Organic Debate project.

Learning Objectives:

• Students will be able to apply their knowledge of chemistry and independent research to create an informed opinion on the benefits and disadvantages of organic foods.

The debate will take place Friday, 4 March!

You will need to hand in your research and be prepared to talk about your position!

Class of: 22-Feb-2016.

Today we covered Section 8.3: Organic Compounds (p. 215).

Learning Objectives:

• Students will be able to explain the importance of carbon to organic compounds.
• Students will be able to recognize organic compounds and classify them as such.
• Students will be able to draw simple organic compounds given the chemical formula.

I hope everyone had a nice long weekend! Today was a tough day, but we made it through all the material we needed to catch up on and are now exactly where we need to be! Woohoo!

Please work through the following review problems:

p. 220 #1-12

Class of: 18-Feb-2016.

(I didn’t get to this yet in Block B. Don’t worry, we will catch up!)

Today we covered Section 8.2: Another Look at Bonding – Lewis Diagrams (p. 210).

Learning Objectives:

• Students will be able to draw Lewis diagrams to represent atoms, molecules, and ions.

Your body cannot dissolve all of chewing gum! The digestive system is able to absorb the sugar and flavourings used, but the gum resin itself does not dissolve in the acid. The resin used to be made of sap from the Sapodilla tree, but now synthetic materials are used.  For example: butyl rubber, which is also used to make inner tubes! Acids dissolve things by reacting the H+ ions with the material to break its bonds and therefore break it apart, and stomach acid is not strong enough for the H+ ions to react with the rubber.

Have a fantastic long weekend!!!

Please work through the following review problems:

p. 214 #1-6

Class of: 17-Feb-2016.

Today we started Chapter 8: Classifying Chemical Compounds and covered Section 8.1: Classifying Inorganic Compounds (p. 201).

Learning Objectives:

• Students will be able to classify compounds as organic or inorganic.
• Students will be able to classify inorganic ionic compounds as acids, bases, or salts.

Please work through the following review problems:

p. 209 #3-16

Class of: 16-Feb-2016.

Today we did a lab! It was Chapter 7’s lab: Investigating Ionic and Molecular Compounds. The report format instructions and discussion questions are located in the Chapter 7 Lab post.

The lab report will be due Wednesday, 24-Feb-2016! Be ready! Do a great job!

There is also a small quiz tomorrow. You will need to know how to change an atom to an ion by adding or losing electrons. You must know how to  classify a compound as either molecular or ionic, then know how to write the chemical name of that compound AND how to write the chemical formula of that compound. Also you should know the properties of ionic versus covalent compounds and how their structure looks down at the atomic level (hint, we covered that in our lab today!)

Take a look at the outline below. Read it over and answer the pre-lab questions, please!

Sci 10 7.L Checklist

Class of: 15-Feb-2016.

Today we covered Section 7.4: Molecular Compounds: Chemical Formulas and Naming (p. 192).

Learning Objectives:

• Students will be able to name a molecular compound given the chemical formula, and produce the chemical formula given the name.

As it turns out, there is a system for naming molecular compounds that require prefixes above 10. The problem is that the naming conventions get very complicated. The prefix for 11 is “undeca-,” 12 is “dodeca-,” and 13 is “trideca-.” Not so bad, but when you get to 31 the prefix is “hentriacontra-.” Ew.

Some other notable examples: 1000 is “kilia-” and 2000 is “dilia-.” What’s the dilia with that??

We have a small quiz on Wednesday, 17-Feb-2016 on Chapter 7!

We have a lab tomorrow on Tuesday, 16-Feb-2016! Please read the Chapter 7 lab post above and prepare answers to the pre-lab questions by then!

Please work through the following review problems if you did not already finish them during class:
