Unit 1 Test
Hi, I was wondering what the format for this test would be (M/C, short answers etc.?), and I was wondering how many marks are in each section.

Test
1) 12 MC

2) The rest of the test is very similar to the quiz outline.

Good luck on the test tomorrow everyone

Ch. 6 Review

please help! thank you
hi miss

im sorry but i had forgotten what is being covered for tomorrow test chapter 5 and 6. and if you could kindly please post UNit 3 & 4 review and work.

Thank you so much this is gladly appreciated

Test for Monday
What is covered on the test is basically the notes I gave in class. Pay attention to graph-diagrams on enthalpy and the rate law.

Know your calculations.

Unit 3 Review is above this note.

Chapter 6 review is above unit 3 review.

About Quiz
There was some confusion with regards to the quiz ==> MnO4 is reduced and Se is oxidized.

So the test remains out of /22, an no extra marks were given.

If you have any questions about the quiz please speak to me on Thursday, when you pick up your marks.

Good Luck tomorrow

About the Exam and Final Marks
I have marked everyone's exam and calculated the final grades. The last unit test is out of /25. This has been a very intense course for you and congradulations for doing such a great job. Hopefully, everyone has learned some chemistry and especially I hope this course has prepared you to know what to expect in University and/or College. Its not the amount of time studying but the understanding and thinking that is needed. I assure you that you are now prepared to endure any course you may take in the future: as long as you do all the work, study all the material, but most importantly understand it. It has been a pleasure teaching all of you and I wish you the best in your future.

Sincerely,

Teach.

Relating Chemistry and Catholicity
A University professor challenged his students with this question. "Did God create everything that exists?" A student bravely replied, "Yes he did!" "God created everything?" The professor asked. "Yes sir", the student replied. The professor answered, "If God created everything, then God created evil,  since evil exists, and according to the principal that our works define who  we are, then God is evil." The student became quiet before such an answer. The professor, quite pleased with himself, boasted to the students that he had proven once more  that the Christian faith was a myth. Another student raised his hand and said, "Can I ask you a question professor?" "Of course", replied the professor. The student stood up and asked, "Professor does cold exist?" "What kind of question is this? Of course it exists. Have you never been  cold?" The students snickered at the young man's question. The young man replied, "In fact sir, cold does not exist. According to the laws of physics, what we consider cold is in reality the absence of heat. Every body or object is susceptible to study when it has or transmits energy, and heat is what makes a body or matter have or transmit energy. Absolute zero (-460? F) is the total absence of heat; all matter becomes inert and incapable of reaction at that temperature. Cold does not exist. We have created this word to describe how we feel if we have no heat." The student continued, "Professor, does darkness exist?" The professor responded, "Of course it does." The student replied, "Once again you are wrong sir, darkness does not exist either. Darkness is in reality the absence of light. Light we can study, but not darkness. In fact we can use Newton's prism to break white light into many colors and study the various wavelengths of each color. You cannot measure darkness. A simple ray of light can break into a world of  darkness and illuminate it. How can you know how dark a certain space is? You measure the amount of light present. Isn't this correct? Darkness is a term used by man to describe what happens when there is no light present." Finally the young man asked the professor, "Sir, does evil exist?" Now uncertain, the professor responded, "Of course as I have already said. We see it everyday. It is in the daily example of man's inhumanity to man. It is in the multitude of crime and violence everywhere in the world. These manifestations are nothing else but evil. To this the student replied, "Evil does not exist sir, or at least is does not exist unto itself. Evil is simply the absence of God. It is just like darkness and cold, a word that man has created to describe the absence of  God. God did not create evil. Evil is the result of what happens when man does not have God's love present in his heart. It's like the cold that comes when there is no heat or the darkness that comes when there is no light." The professor sat down. The young man's name -- Albert Einstein

Dear Ms.,

Good evening and how are you? I'm just wondering if you could advice me what to take between the "Chemistry Grade 12 College" or "Chemistry Grade 11 University"? I don't know which is the most appropriate for me to take.

And also about the "Grade 12 Mathematics College", will I have to take the college apprenticeship mathematics or mathematics for college technology?

I'm hoping you answer all my questions because I have to register for these courses asap. And by the way I'm one of your student from Chemistry 12U and I hope you remember me.

Thank you again and God Bless you, Lydia M.

Answers
HI Lydia, I got your message. I think that you would be able to do the Chemistry College 12. The prerequisite courses that you would need is Grade 10 applied CHemistry. And through this course you were able to get some foundations in Chemistry.

Grade 11 University Chemistry is challenging. You have to do several complex calculations. If you were to take this course I think you should take it in day school where you can learn a little each day. And at the same time invest in a tutor so if you need refresh from the grade 10 curriculum. Also, please be observant with the calculator and its functions. You can do it but it just takes some guidance from the teacher and practice.

College Mathematics I am not sure about. Again it might be good for you to take because you can practice using the calculator. However I don;t have first hand experience with these courses.

Hope this helps. Take Care and God Bless. Write again and let me know how things work out.
