Molarity or Molar Concentration

Today in class, we covered "molarity" or "molar concentration".

I gave a handout for molarity which is called "Hebden - Molarity problems". You can find it by clicking the link on the right "Mole Conversions Notes".

I will have the booklet uploaded in Google docs by 8:00 pm tonight!

Have a great weekend!

God bless you all,

Mr. MacLennan

Science 10 Acids & Bases Test

Hello everyone,

Today in Science 10, we wrote a test on acids, bases, and pH.

There is multiple choice, naming & formulae of acids, and a long answer question which is based on chemical reactions.

Learn what the indicators are and how to use the pH scales. Read your textbook for the answers.

Those of you who did not have the chance to write it yet, you will write it Monday after school or Wednesday after school BECAUSE we need to review rates of chemical reactions and have a quiz in it before exams rolls around (please!)

The more tests you give me, the more material I have to give you a mark. That's it!^^

See you soon, good job vball girls,

God bless you all,

Mr. MacLennan

CE 10 December Exam

Hello class,

FIRSTLY:

As of today, I will be meeting with my colleagues teaching CE 10 and we will change the format of the Christmas examination so that it will cover more of the material you have been learning in my class.

The exam format will most likely be no multiple choice and only essay-type questions.

Please check this blog for any updates on the status of the CE 10 December examination.

I can tell you this: One of the essay questions will depend entirely on your understanding of the Human Act rubric we have been working on.

SECONDLY:

The homework due for this class was to fill out a human act rubric based on an event or goal in your own life.

I have 5 people who passed it in on time. Congratulations to you five. Come see me for your marks on Friday.

Please get it in to me, it will help you for exam prep.

THIRDLY:

Keep posting on the Community Forum (www.stephencovey.com)! I will tally them all up and it will tell me a lot about consistency (another virtue that I am not so good at yet).

FOURTHLY:

Start studying for all your exams THIS WEEK!

FIFTHLY:

God bless you. Pray for me.

Mr. MacLennan

Acids & Bases

Today in Science 10, we reviewed (AGAIN) acids & bases.

The acids & bases test will be on Monday.

We will review the factors affecting the rates of chemical reactions next and quiz it if we have time.

God bless you,

Mr. MacLennan

Molarity or Molar Concentration

Today in class, we went over the answers to last class' homework. The answers to the mole conversions handout from last class and all other moles notes can be found in the link on the right of the blog under the heading CHEM 11 ("Mole Conversion Notes").

The Answers for Unit 4 can be found under "BC CHEM 11 Answers", also to the right.

<><><>

We also covered an introduction to molarity and molar concentration.

mol <-- solute

L <-- solvent

<><><>

HOMEWORK: Workbook questions pp. 153, 154, 157 (questions within the chapter)

Using density in mole conversions

Hello class,

Today we practiced more mole conversion questions, but using density (g/mL) as a unit conversion factor to solve particular problems.

The link to all the moles notes we have covered so far is to the right.

Click the link titled "Mole Conversions Notes" and find today's notes: "U4.3 Multi-Conversion Mole notes (blank).doc"

You can also find the ANSWERS in the file "U4.3 Multi-Conversion Mole notes.doc"

God bless you all,

Mr. MacLennan

Acids & bases REVIEW

Hello everyone,

today, we reviewed acids & bases further.

Here is a link to a helpful site for studying.

http://lrs.ed.uiuc.edu/students/erlinger/water/background/ph.html

Also, make sure you know these chemical reactions:

acid + base --> a salt + H2O

metal oxide + H2O --> metal hydroxide (base)

non-metal oxide + H2O --> acid

acid + metal --> a salt + H2 (gas)

acid + any carbonate --> a salt + H2CO3 + CO2

These equations are found in your notes titled "SALTS"

To download any of the notes we have been using in Sci 10, look to the right of the blog under the heading SCI 10

God bless you,

Mr. MacLennan

CE 10 - Human Act Rubric

Hello class,

We have been working on perfecting our understanding of the breakdown of the "human act"--or deliberately willed actions.

To the right is a link to a downloadable "human act rubric" that you have been using in class.

Unit Conversions - Litres to Moles

Today in Chemistry 11, we worked with converting between litres and moles using the conversion factor

22.7 L gas @ STP/mol

Remember, it MUST be a gas, and it MUST be at Standard Temperature & Pressure ("STP").

To access the unit conversion notes, click the link to the right of this page under the heading CHEM 11 entitled "Mole Conversions Notes"

Take care,

Mr. MacLennan
