Hello guys! Welcome to KEM KORNER!

This page, I hope, will help you obtain a deeper understanding and appreciation of basic and not-so-basic chemistry concepts. For those looking for entertainment, there will be bits of that here although I'm not so sure yet how I'll go about this "entertainment" thing. But I assure you that this blog will be filled with links, downloadables and test-yourself questions that will help you, in some way, improve your understanding of the world of chemistry.

Suggestions, contributions and reactions, violent or otherwise, are also welcome... :)

With a 4-carbon organic compound as basis, complete the following table. (Please use a long-sized bond paper in preparing this table.) Ms. De Leon will collect all finished activity papers.

Scoring: Normal structures will get 1 point. Branched structures, 2.


To My PT Class


Please answer the following questions. Use 1 whole sheet of paper. Mr. Severo will collect your papers at the end of the period.
You may refer to the powerpoint presentation we were using to answer these questions.

1.  What is hybridization?
2.  How is a hybridized C formed?
3.  What are the differences between a sigma bond and a pi bond?
4.  How are atomic orbitals different from bonding orbitals?
5.  Enumerate and differentiate from each other the 3 types of hybrization.

Online Test for Metabolism



To My Biochem Students...

The questions I have posted for this test are of 2 types: True or False and Identification. The questions will randomly appear as you click the "submit my answer" tab on each page. This means the sequence the questions will follow is unique for each quiz-taker. Make sure you enter the correct spelling of the words for questions under the identification type.
You are given 45 minutes to finish answering all the questions. Your result will appear after the 40th question is answered. Please print the certificate generated by the site at the end of the test. Submit such to me on the next lecture class meeting.

Please click here to go to the quiz page... Good luck!

P.S.
To help you get the hang of taking online tests, I have posted a 10-item practice test found on this page. There's no limit to the number of times you may take this 4-minute test. You also have the option to print the score report that will appear at the end. Scores you get in this test will not be recorded.

Biochemistry Experiments for Prelim

These are the links to the download pages of your prelim lab experiments. I’m assuming that since you were able to reach this site, you know how to click on links and download files… :)

Seriously though, before anyone attempts to set foot in the lab room, make sure that, aside from the other materials you're asked to bring, you carry a hard copy of the laboratory activity for the day. Remember, NO HARD COPY, NO EXPERIMENT and you’ll get 60 for the day.

Other reminders:

1. Use short-sized bond paper when printing or photocopying the activity sheets.
2. Brief answers to questions are encouraged. Confine your answers to the spaces provided after each question.
3. Write legibly. Maintain cleanliness of your report papers. Use a pen when writing down your answers. A pencil may be used if you're asked to draw or illustrate certain set-ups.
4. Staple the pages of your report before submitting such to me.

Please click the titles of the experiments found below to go to the download pages.

Thank you very much...
