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... :)

Final Exam



Hello guys!

I have posted a 60-item MULTIPLE CHOICE test 👉🏼 here 👈🏼. This test covers the following topics: (1) Detecting Anions, (2) Gravimetric Analysis, and (3) Volumetric Analysis.

Before taking the test, you are required to type in your EMAIL ADDRESS and SECTION FAMILY NAME, FIRST NAME, MIDDLE INITIAL (ex. T1 Cabaña, Patricia H.). You have 2 hours to finish and "submit" the test.

The test will be available thrice daily from April 24, Friday to April 26, Sunday. The daily schedule of test-taking will be as follows:

  10:00 AM - 12:00 PM
  4:00 - 6:00 PM
  9:00 PM - 11:00 PM

For those who will not be able to take the test on the given schedules, please email me at 
👉🏼 mcabana@usi.edu.ph 👈🏼 I will reopen the test once your internet situation has improved. Whenever possible, please ask for a schedule by cluster or group. Let’s say 3 of you who haven’t taken the test may ask for the same schedule for the reopening of the online test.

There are only 3 requirements for this final period. The flowcharts you submitted (which will be credited as final PT), the 60-item long test and this final exam. We were instructed that an INC mark shall be given to students who are unable to comply with the requirements. You will then be given the next semester for completion.

I have again limited the number of test-takers to 125. This number corresponds to the total number of students in T1, T2, and T3 so please do not take the test more than once by entering another email address. You will be depriving others of their test slots.

I will also be posting all your grades online starting next week.


                                                                                                       Praying for everyone’s health and safety, 
                   
                         🙏🏼MCabaña🙏🏼

Hello BSMT!

I will be posting the link to your online final exam here in kemkorner on Friday, April 24 at around 8AM. It will be a 50-item test.

Topics covered will be (1) detecting anions, (2) gravimetric analysis and, (3) volumetric analysis.

Problems in the exam will be similar to the ones I have included in the presentations.

Please stay at home!

Hello BSMT!

The presentation for Volumetric Analysis is now ready for download 👉 here. 👈  File is in PDF.

I would also recommend that you watch these short video clips just so you will have an idea how Volumetric Analysis / Titration is done. 



Have a Blessed Holy Week! 

🙏🏼 MCabaña 🙏🏼

Good morning BSMT!

Today is Tuesday, March 24, 2020.

There were 94 students out of 125 who were able to take the online test yesterday. Thank you 🙏🏼 and congratulations 🥳 to all of you for your perseverance and resolve in accomplishing school work in spite of the difficulty 👏🏼🥰👍🏼  I'll be releasing your scores via email once all 125 of you have taken the test.

There were some of you who emailed me to ask to take the test today. I shall, again, open the test from 1PM to 5PM later today to accommodate these requests. Also, quite a few of you have asked to take the test at midnight as this is the time your internet connection is faster. I will also open the test from 10PM to 3AM tonight 😴🌛✨

Comment below this post or email me if you have other "time sked" in mind.

God bless us all!

To My BSMT Classes

Hi guys!

As announced earlier, our next topic is Gravimetric Analysis. I hope by this time you already have an idea what this analytical method is about. This was introduced to you in Chapter 1. A more detailed explanation of this method is discussed in the powerpoint presentation below. Just click the image to download your copy of the presentation.



Please study the presentation. There are three (3) sample problems that were discussed thoroughly in the presentation. Steps in solving the problems are shown. Please study them and once you get the logic behind the solutions, try solving similar problems like 👉🏼 these 👈🏼.

I don't expect you to fully understand how problems on Gravimetric Analysis are solved. If you have questions, you may use the comment section below this post for your queries or send me an email. 

I'm not sure if we will still be able to conduct experiments on Gravimetric Analysis in the laboratory. To cover this part, I would like you to watch youtube videos. These video clips will at least give you an idea how gravimetric analysis is done inside the laboratory.




Visit this page from time to time for additional explanations to specific gravimetric problems I gave above. 

Thank you and God bless us all!
