Chemistry- Rubric for Environment and Energy Paper

Please find the rubric for the Environment and Energy paper attached below. Please be reminded that the paper is due by e-mail by Friday, March 27, 2009 by the the beginning of class. I strongly advise you to send your paper the night before and verify with me during colours whether or not I received it. If the paper is not in by the start of the class, you will receive a mark of zero. Please remember Mr. Cleland’s advice about ensuring that your paper is in the correct format.

Chemistry- Tuesday, Feb. 10, 2009

So far, we have introduced the law of conservation of energy and how it applies to different systems.

We completed the heat transfer activity which allowed us to test for the different factors that need to be considered when discussing heat transfer in a system.

You are expected to complete the handout for today’s activity and bring it to class tomorrow.

Exam Reminders- January 23, 2009

Just a few reminders for the upcoming exams….

  • The only required material for the math, physics and chemistry exams are pencils, erasers and calculators. Other material (paper, periodic table, etc) will be provided.
  • Please remember to bring all texts and other borrowed material to the exam. These text books will be collected at that time. You are accountable for your texts!
  • Physics students are permitted to bring their formula sheet if there no notes written on them.
  • Anyone with questions about the material can contact me via e-mail or see me during the time frame between exams.

Best of luck!

Chemistry- Electric Car Comes to Canada?

I recently found an interesting article on the potential development of an electric car infrastructure in Canada. I highly recommend reading this article- perhaps there is hope!

Chemistry- Information for the Final, January 15, 2009

Chemistry 11: Exam Information

General Exam Info

The grade 11 chemistry final is divided into 2 sections:

  1. Oral Component (10% of final grade)
  2. Written Component (40% of final grade)

The oral exam will be conducted on Wednesday January 21 and Thursday January 22 in class. The oral exam is 5-10 minutes long and will require you to discuss a topic that we studied in class.

The written exam will be on Tuesday January 27th from 9AM-12PM.

Review Dates

In-class review time will be provided on January 16, 19, 20 and the 21st or 22nd (differs for each student depending on the date of their oral exam).

Availability

There will be additional time available outside of class on the following dates:

Monday, January 19- 3:00-4:30PM (general)

Wednesday, January 21- 12-12:30PM (general), 3:00-4:00PM (chemistry only)

Thursday, January 22- 12-12:30PM (chemistry only)

Please bring questions or issues to tutorials to help structure the tutorial.

Topics Covered

All the topics covered in the semester may appear on the exam. There is greater weight on post-midterm material than there is on pre-midterm material.

  • Avogadro‚Äôs Number
  • Moles and Mole Conversion (how and when to use it)
  • Molar Volume of Gases (how to apply it to problems)
  • Percentage Composition of Compounds (how to find it and use it)
  • Law of Definite Proportions
  • Law of Combining Volumes
  • Empirical Formulae (what is it, how to find it)
  • Molecular Formulae (what is it, how to derive it)
  • Hydrated Ionic Compounds (what are they, why are they significant, calculations with them)
  • Balancing Equations (how to do it as well as how to use them in solving problems)
  • Stoichiometry and Stoichiometric Calculations (importance and how to use it)
  • Limiting Reactant (why it is used, solving for it, applying it to reactions)
  • Percentage Yield (how to find it, why it is needed)
  • Percentage Purity (how to calculate it and use it to determine product formation)
  • Classifying Hydrocarbons (intro to organics, naming alkanes, alkenes, alkynes; combustion)
  • Bond Formation (ionic, covalent, Lewis dot diagrams)
  • Electronegativity
  • Intermolecular Forces and Intramolecular Forces
  • Symmetrical/Asymmetrical Addition to Alkenes, Cyclic Hydrocarbons, Aromatic Hydrocarbons

Physics- Review of Some Topics, Dec. 1, 2008

Just a quick review of some of the topics we have covered since the midterm…

Work

W= Fd

– work is defined as a transfer of mechanical energy

– it causes an object to change or move

– work is always done on an object

– is measured in N*m

– review the conditions for when work is done (work is not done hen there is no change in condition, there is uniform motion or if the force applied is perpendicular to the direction of the motion)

– Review practice problems #1-3 on page 221 and #4-10 on page 225 for a refresher

Momentum

p = mv

– the momentum an object possesses is related to the product of its mass by its velocity

– the direction of the momentum is the same as its velocity (is a vector)

– has a unit of kg*m/s

– used when dealing with non-elastic collisions- it’s easier to describe the “quantity of motion” of an object before and after a crash than to try and analyze it during the moment of

Impulse

J = F(delta)t

F(delta)t= (delta)p

F(delta)t = mv2-mv1

– is the product of the force exerted on an object and the time interval over which the force acts

– impulse is a measure of the change in momentm

– direction of impulse is the same as the direction of the F applied

– unit is in N*s

– Review problems 29 on 197, 30-32 on 200 and 33-35 on 203

For additional problems, check out: #37-42 on page 209 and #15, 17, 20, 23-28 on page 275 and 276.
