Graph1. Change in Temperature of H₂O
Energy diagrahm of water

a) When there is a change in temperature or kinetic energy of an element or compound, q=mc∆t is used to determine the enthalpy (or energy) change.

In the graph above, regions A, C, and E display a change in temperature. Since ∆t represents a change in temperature, t_f - t_i, q=mc∆t is used to determine the energy change within those regions.

b) When an element or compound undergoes a change in phase, represented by regions B and D, q=n∆H is used to determine the enthalpy change within those regions.

Regions B and D show no change in temperature (kinetic energy). In B, ice melts into water. In D, water vaporizes. When there is a change in phase, no temperature change is observed; therefore, q=n∆H must be used to determine the enthalpy change. ]]>Basic Exponentsyoonsmon@gmail.commath2009-10-11T09:25:01-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/c0af89ddad0fb1a1ef8c6540511acc07-24.html#unique-entry-id-24http://www.calgaryhighschooltutor.com/tutoring_blog_files/c0af89ddad0fb1a1ef8c6540511acc07-24.html#unique-entry-id-24a

Whenever a vector is given at angles other than 0^o, 90^o, 180^o, 270^o, or 360^o, the vector just be broken into its X and Y components.

For the example above, the velocity of the projectile is 45 m/s at 30^o to the horizon.
By using trig functions, we get the following setup:

Trignometric function set up of Projectile

Trignometric function set up of Projectile

Vx

cos 30^o = Vx/45

Vx = 45cos(30^o)

Vx = 38.9 m/s

Vy

sin 30o = Vy/45

Vy = 45 sin(30^o)

Vy = 22.5 m/s

Whenever a question gives vectors at an angle, remember to convert the initial vector into its X and Y components by using trigonometric functions.]]>Cold/Flu Season and Schoolyoonsmon@gmail.comhealth2009-10-05T09:50:32-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/03fd378825ffbc0f14bddaec01178b7a-22.html#unique-entry-id-22http://www.calgaryhighschooltutor.com/tutoring_blog_files/03fd378825ffbc0f14bddaec01178b7a-22.html#unique-entry-id-22It’s October and on days like today where the temperature is beginning to feel cold and with recorded signs of snow overnight, you know it’s the cold and flu season. The last thing anyone wants is to catch the cold or the flu especially with the current alarm of the H1N1 flu virus.

Well, what can you do as a student to prevent the spread of the cold and the flu in school?

1) Wash your hands thoroughly. Washing your hands does seem simple but just read Canada Health guide of washing your hands.

2) Keep an alcohol based hand sanitizer close.

3) Cough or sneeze into tissue, so keep some tissue in your pocket or backpack. As a last resort, cough or sneeze into your sleeve if there are no tissues close by.

4) Just be aware of the spots around school where you know it will be a potential place for infections like door knobs, stair rails or along the lockers.

5) Do not rub your eyes and avoid touching your face. Your eyes, nose and mouth are points of entry for bacteria and virus to infect your body.

6) Keep your immune system strong by sleeping well and eating healthy.

7) If you are feeling sick, stay home. Don’t risk spreading the cold or the flu to others.

If you’re curious about more information, Canada Health has a great link with all the information. ]]>Naming Organic Compoundsyoonsmon@gmail.comchem2009-10-01T21:01:48-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/f4f5198e91c680a3b1afeb4a60ef6f76-20.html#unique-entry-id-20http://www.calgaryhighschooltutor.com/tutoring_blog_files/f4f5198e91c680a3b1afeb4a60ef6f76-20.html#unique-entry-id-20Basic Hydrocarbons

Strong acids dissociate 100%.
What does this mean?
It means that all hydrogen ions are released allowing it to react with any anions. Therefore, strong acids are very reactive.
eg. HCl, H₂SO₄, HNO₃

Weak acids dissociate less than 50% which make weak acids much less reactive than strong acids.
eg.

The key to writing well is to write and rewrite your work until the day it's due. Here is an example to manage your time and to get started on any writing assignments.

Lets say it's Monday and your assignment is due the following Monday.

Monday
-write the thesis & topic sentences
-build your outline
-find 2-3 examples from the literature to support each of your topic sentences

Tuesday
-get a rough draft of your introductory and one body paragraph completed
-go over your outline and make sure your sentences are ON TOPIC

Wednesday
-complete a rough draft of your remaining body paragraphs
-read over the paragraph you wrote the previous day, make sure your sentences are ON TOPIC
-reread them again to make sure your sentences make sense and that your thoughts are expressed clearly

Thursday
-finish the rough draft of your concluding paragraph
-read over the paragraph you wrote on Tuesday and Wednesday
-check them to make sure the sentences are focused and contain appropriate examples to support your topic sentences

Friday
-reread your drafts, checking for mistakes and rephrase any sentences that are unclear
-get a friend or parent to reread your paragraphs for mistakes

Saturday
-reread and rewrite any sentences that do not support the topic of your thesis or topic sentences

Sunday
-reread and check for any spelling or grammar errors
-rewrite to make your sentences clear and focused

Monday
-hand in your assignment

By looking at this example, it should be clear that rereading and rewriting your drafts are key to writing well for assignments. Never stop editing your paper until the date they are due!]]>Equation of a Line with 2 Points.yoonsmon@gmail.commath2009-09-23T15:59:02-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/4a6db844eee264795faf733feebbb64a-14.html#unique-entry-id-14http://www.calgaryhighschooltutor.com/tutoring_blog_files/4a6db844eee264795faf733feebbb64a-14.html#unique-entry-id-14
pure math 10 20 30

A) First lets find the slope using the equation:

slope=m=(y2-y1)/(x2-x1)

m=[6-(-1)]/[4-(-1]=(6+1)/(4+1)=7/5

Now lets find the equation of the line using the formula:
y=mx+b and the coordinates (-1,-1).

We know the slope is 7/5 and x=-1, y=-1 from (-1,-1).

y=mx+b

-1=(7/5)(-1)+b
-1=-(7/5)+b
-1+7/5=b
-5/5+7/5=b
2/5=b

Therefore: y=(7/5)x+2/5

B) or another way to solve this question:

We can use the following equation:

(y-y1)=m(x-x1)

from above we calculated m=7/5

(y-(-1))=(7/5)(x-(-1))
(y+1)=(7/5)(x+1)
y+1=(7/5)x+(7/5)
y=(7/5)x+(7/5)-1

y=(7/5)x+2/5]]>Breakfastyoonsmon@gmail.comhealth2009-09-22T16:45:35-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/7387c3ff33e3a3b03af3485dda80098f-13.html#unique-entry-id-13http://www.calgaryhighschooltutor.com/tutoring_blog_files/7387c3ff33e3a3b03af3485dda80098f-13.html#unique-entry-id-13

Transcription refers to all the steps involved in the replication of DNA. Transcription uses one strand of the double stranded DNA as template for replication.

Translation is the process of producing a protein (polypeptide) from mRNA.

Therefore, transcription is the replication of DNA and translation is the synthesis of protein.]]>Speed of Lightyoonsmon@gmail.comphysics2009-09-20T14:13:37-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/1cf396bb6c688e8ab87478752e10bb9c-11.html#unique-entry-id-11http://www.calgaryhighschooltutor.com/tutoring_blog_files/1cf396bb6c688e8ab87478752e10bb9c-11.html#unique-entry-id-11

Covalent molecules contain bonds that share electrons. They can be even sharing of electrons, non polar molecules, or uneven sharing of molecules, polar molecules. Covalent molecules contain bonds between nonmetal and nonmetal.

For example: carbon dioxide, methane, sulfur dioxide.

IONIC MOLECULES

Ionic molecules contain bonds that do not share electrons. The electrons are transferred from a metal atom to a nonmetal atom forming ions, cation (positively charged atoms) and anion (negatively charged atoms). Therefore, ionic molecules are involved in complete transfer of electrons. Ionic molecules contain bonds between metal and non metal.

For example: Sodium chloride, Magnesium oxide, Lithium hydroxide.]]>Steps Toward Memorizationyoonsmon@gmail.combiology study tips2009-09-17T17:36:52-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/3e3e995aa1ac019145530009c29d00fc-9.html#unique-entry-id-9http://www.calgaryhighschooltutor.com/tutoring_blog_files/3e3e995aa1ac019145530009c29d00fc-9.html#unique-entry-id-91) Review your notes at the end of each day. Add 10 minutes of new material into your daily review at the end of the day. For example, if your daily review is 60 minutes per day, use 50 minutes for review and 10 minutes for the new materials you learned in class. If you don’t review the material you learned during the day, you will forget 50-80% of the material within 24 hours.

2) Review your notes at the end of each week. This will reinforce what you have learned during the week and help you retain what you have memorized during the weekday. This step must be used along with step one for effective memory retention.

3) Take a break every 60 minutes. Why? Firstly, most students are able to focus for 60 minutes. Anything longer will only lead to daydreaming and loss of attention. Secondly, short term memory integrates with your long term memory when you stop inputting and take time to relax (this break should be about 10-15 minutes).

4) Change the subject material every hour.
For example:
First hour, review math. Take 10-15 minute break.
Second hour, review chemistry. Take 10-15 minute break.]]>Trig Function Reviewyoonsmon@gmail.commath2009-09-16T17:34:09-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/da5dfff85f1d1f386809b93ff17d3208-8.html#unique-entry-id-8http://www.calgaryhighschooltutor.com/tutoring_blog_files/da5dfff85f1d1f386809b93ff17d3208-8.html#unique-entry-id-8Here’s a quick review of trigonometric functions.

Try to get to bed early. If you get up 7 am during the school days, make an effort to get into bed by 10 pm. Most students need 8-10 hours of sleep per night. If you are well rested, you will be alert in class and be able to pay attention which will without a doubt help you with your academics.

But if you are a student who do find it difficult to fall asleep, here are some tips.

- Sleep only when sleepy. If you can’t fall asleep within 20 minutes of going to bed, get out of bed and do something boring like watching news documentary on PBS, and do not expose yourself to bright light.

- Don't take naps after 3pm. Doing this will help you fall asleep at bedtime.

- Do not exercise within 4 hours of your bedtime. Exercising in the morning or during the day is great for helping you fall asleep but at couple of hours before bedtime, you metabolic rate will be high preventing you from falling sleep.

- Use your bed only for sleeping. Do not use your bed as a place to watch TV, listening to music and even studying. Bed is for sleeping only.

- Get up and go to bed at the same times every day, not only on weekdays but even on weekends. This will become your sleeping ritual.

- Place your computer or laptop outside of your bedroom. There is nothing worse than chatting or playing games until the late hours of the night. Parents, please take note of this tip for your children.]]>Writing on Topic.yoonsmon@gmail.comEnglish2009-09-15T21:53:27-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/9f111d2db6de0f72c11c1998c1da295b-6.html#unique-entry-id-6http://www.calgaryhighschooltutor.com/tutoring_blog_files/9f111d2db6de0f72c11c1998c1da295b-6.html#unique-entry-id-6Many students are capable of writing effective sentences but when their sentences become too long, their sentences lose focus and become awkward to follow.

In addition, avoid using new vocabulary in your assignments or essays. Before you use a new word, make sure you know how to use them in the correct context. Many students pick words from the thesaurus thinking that they can replace words with the same meaning, but they end up using the words inappropriately. ]]>Biologyyoonsmon@gmail.combiology study tips2009-09-13T21:48:00-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/18e058eac2bd493b986627a8ff6258c6-5.html#unique-entry-id-5http://www.calgaryhighschooltutor.com/tutoring_blog_files/18e058eac2bd493b986627a8ff6258c6-5.html#unique-entry-id-5One simple tip but difficult for most students to carry out is to memorize their notes and definitions. So, next couple of blogs on biology will be tips toward effective methods of memorization.

If you are a student, do not kid yourself thinking that you can memorize easily. Memorization takes much work and time. But with practice and constant review, you will be able to retain all important elements to succeed in biology.

Step 1 Towards Effective Memorization: NOTE TAKING

If your teacher gives you handouts for each class, this step is easy for you, but most students are not so lucky.

During class, pay close attention to your teacher’s lecture. Anything your teacher writes or draws on the board or displays on the overhead, record it onto your notes. If your teacher places emphasis on a particular theory, cycle, or diagram, write it down. 70%-80% of your examination will be based on your teacher’s lecture so pay close attention.

During your spare or your study time at home, read over your notes. If your notes are messy, rewrite it and make them legible. Designate a coiled notebook for you biology notes. It will be convenient to carry around and to read. There is nothing worse than having your binder pop and scatter your invaluable class notes.

Use post it to separate different units, eg. red tags for biochemistry, blue tags for the nervous system.

Use highlights to mark important vocabulary or section that your teacher emphasized in class.

Keep your notes updated after each class. DO NOT wait till the end of the week or the weekend to catchup on your notes. In order to do well in biology, it is important to not fall behind on your notes.

Important points:

-Keep your notes updated
-Keep your notes neat
-Keep reading your notes everyday
-Keep your notes with you always in your school bag.

A common question I get from all students.

The simplest answer - it is a compound containing 2 oxygen atoms joined by a single bond. Peroxides are highly basic. Common peroxide is hydrogen peroxide which is used as bleach and also as a disinfectant.

For example, R-O-O-R’ or H-O-O-H (hydrogen peroxide).

When most students see 2 oxygen atoms in a chemical formula, most assume the oxygen has an ionic charge of -2; thus, O=O (diatomic element of oxygen). However, when 2 oxygen atoms are bonded to 2 metallic elements such as the elements in Group 1, the oxygen atoms bonded to these metals have a charge of -1, resulting in a peroxide. eg. Potassium peroxide, Lithium peroxide. ]]>Wednesday Math yoonsmon@gmail.commath2009-09-08T14:55:35-07:00http://www.calgaryhighschooltutor.com/tutoring_blog_files/5b03b527c253d4d8c102e18c3d6a0e11-1.html#unique-entry-id-1http://www.calgaryhighschooltutor.com/tutoring_blog_files/5b03b527c253d4d8c102e18c3d6a0e11-1.html#unique-entry-id-1One common difficulty I see students having is adding fractions that do not have a common denominator. Whether students are grade 10 or grade 12, even university students have a bit of difficulty with this one. It should be part of any students review for the start of the new semester.

This example does seem simple and there are variations but it’s one factor in the beginning of the semester that is becoming very important as students progress into their semester.

I do give my students an outline on writing the thesis properly but the main components of writing the basic thesis includes stating the title, the author, the significant event and the topic of the essay.

The most underestimated factor for writing an effective thesis is just practice, writing it over and over again using many different essay topics.]]>
