Honours Roll for End-of-Semester

Dear all,

Hi. We have all survived Term 2 and it is time to celebrate your successes in the past Semester. I've done some results analysis and here are the lists of Top Students and Most Improved Students.

Congratulations to all.

Lesson Objectives for Kinetics

Yoz,

Here's the learning objective for the recently concluded topic.

Of course, not to forget our Boltzmann's distribution curve and using it to explain how increasing temperature or presence of catalyst helps to speed up rate of reaction.

External DMP Modules

Dear All,

Hi. Just a reminder about the three external DMP Modules that will be conducted in the June Holidays:

- Fragrance Chemistry (S$75) 11 - 14 Jun 0900-1200 hrs
- Environmental Chemistry (S$80) 4 - 7 Jun 1300-1600 hrs

- Pharmaceutical Chemistry (S$85) 4 - 7 Jun 0900-1200 hrs

Venue: RI Science Labs

Please collect the Edusave form from me (by Monday) if you are interested.
Note that the registration is at the Atrium on 15th May or 17th May (1030 - 1130).

Otherwise, you can wait till Term 4 for the other 6 interesting DMP Chemistry modules conducted by our very own Chem Teachers.

Enjoy your weekends.

The Old and New Sources of Energy

Yoz,

We have come to an end for the topic of Energetics. Besides knowing about exo and endothermic reactions, we also discussed about alternative sources of energy.

Here's an article discussing the cost of coal on the environment and the global economy.

We have talked about using fuel cells as an alternative source of energy. But what is preventing this technology from becoming so widely used? One problem is with the storage of H2. What is being done about this? Read this for an idea.

What other ways are possible? Maybe some bright sparks among you could win the next Nobel prize with this. Do contribute your wildest idea in the comments.

Next Week's Programme

Hi.

I understand that next week would be very stressful for you guys. As such, let me list down what will be happening for chemistry lessons in the next 3 weeks:

Sec 4A/4C/4I/4P - P1 = Kinetics Practical 1 (LAB); P2 = Kinetics Practical 2 (LAB)
Sec 4J - P1 = Energetics OBA + Fuel Cell and Electrochemical Cell OBA; P2 = Kinetics Practical 1 (LAB)
Sec 4Q- P1 = Fuel Cell and Electrochemical Cell OBA; P2 = Kinetics Practical 1 (LAB)
*Sec 4A and 4P will be having the Fuel Cell and Electrochemical Cell OBA during CCT Period on Wed.

To help lower the stress level, ALL the OBA above are not graded. But do come prepared, else it will be a useless exercise.

For Week 9, it will be a week of assessment (all counted; 5% each). One period will be for Energetics Practical; the other for Energetics Pen-and-paper Test (Closed book).

Week 10 will be used to finish up the topic on Kinetics.

Enjoy your weekends.
