Hi Students,

2 months to GCE O Level, Have you scored the marks you truly deserved?

Is Mole Calculations your #1 Killer Topic?

Click here to find out more



Over the years, this topic is often voted the “Hot Favorite” on students’ challenging topics. Some have

- problems understanding what the question is asking for,
- do not know where to start,
- totally blank when they read the question,
- too confused with the formulaes to use…WHY?

Let’s check out a typical exam question on Mole Calculations:

Question:

The following equation represents the precipitation reaction between lead (II) nitrate solution and potassium iodide solution.

aPb(NO3)2(aq) + bKI(aq) –> cPbI2(s) + dKNO3(aq)

In an experiment, 20.0g of lead(II) nitrate and 20.0g of potassium iodide were dissolved separately to form 250cm3 of lead (II) nitrate solution and 250cm3 of potassium iodide solution.

(a) Determine a, b, c and d. (2 marks)

(b) Using suitable calculation, identify the limiting reactant. (2 marks)

(c) What is the maximum mass of lead (II) iodide (PbI2) that can be obtained from the experiment? (2 marks)

(d) What is the concentration of potassium nitrate in the reaction mixture when the reaction is completed? Give your answers in mol/dm3. (2 marks)

(e) Write an Ionic Equation for the above reaction and identify the spectator ion. (2 marks)

Here is the answers:

a) a = 1 , b = 2, c = 1 and d = 2

b) KI is the Limiting Reactant.

c) Maximum mass of PbI2 that can be obtained = 27.8g (to 3 sf)

d) Concentration of KNO3 = 0.241 mol/dm3

e) Ionic Equation: Pb2+(aq) + 2I-(aq) à PbI2(s). Spectator Ions: NO3-(aq) and K+(aq)

PS: If you cant solve those questions comfortably, i strongly encourage to join us at the Mole Calculations Mastery WOrkshop on 16th Aug, where you know everything that you need for Mole Concepts, before your nearing Exams.

Chemistry Jokes

Two hydrogen atoms bumped into each other recently.
One said: "Why do you look so sad?"
The other responded: "I lost an electron."
Concerned, One asked "Are you sure?"
The other replied "I'm positive."

Indeed true. Hydrogen atom will become a Proton (H+)
when loses an electron and becomes positively charged.

Chemistry make Harry Potter Invisible

(By omg_itsemilye)

US researchers creates material that could make wearer of that material invisible. This will certainly make the fiction-based Harry Potter cloack to become a non-fictional reality.
Black will be getting blacker. US researchers had reported in last month that they have created a paper-thin material that absorbs 99.955 per cent of the light that hits it. This is about 30 times as dark as the international current standard for blackest black. As we learnt also in fundamental physics, we see the color of the object because of the primary light fractions that are not absorbed by the material (that light falls on) and REFLECT back into our eyes. This research results will make objects inside of them literally invisible under the right conditions. It will be very black, like in a forest on the darkest night. Nothing comes back to you. It will be very very very dark.

The substance is made of carbon nanotubes: - they are microscopic, hollow fibres whose walls are just one atom thick. Its creation reflects researcher’s growing ability to manipulate material(atoms) and light. The material bends light rays “backward”, a phenomenon thought to be impossible just a few years ago. This phenomenon forces some wavelengths of light to flow around an object like water around a stone (imagine it). As a result, things behind the object become visible while the object itself disappears from view.

(By answers.com)

Carbon nanotubes (CNTs) are allotropes of carbon and essentially organic compounds.
A single-walled carbon nanotube (SWNT) is a one-atom thick sheet of graphite (called graphene) rolled up into a seamless cylinder with diameter on the order of a nanometer. This results in a nanostructure where the length-to-diameter ratio exceeds 10,000. Such cylindrical carbon molecules have novel properties that make them potentially useful in many applications in nanotechnology, electronics, optics and other fields of materials science. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat

Recommended Books to Master Chemistry

I was approached by a parent as well as a teacher on the recommendation of any interesting Chemistry books that can intrigue the liking of Chemistry for their child/students respectively. After recalling some of the books that i have read before that are interesting, i would like to recommend the 1st Chemistry book titled: "Chemistry for Dummies" which touches on the fundamentals of chemistry in everyday life.

We’re all natural born chemists. Every time we cook, clean, take a shower, drive a car, use a solvent, such as fingernail polish remover, or perform any of the countless everyday activities that involve complex chemical reactions we’re doing chemistry. You might even say

Options Galore - Choosing the Right Path for O-Level holders

Halo Students & Parents,

It is the time of the year that the graduating students are looking forward to - the release of the GCE O Level Examination Results at 2pm on 24th Jan 2008 - according to the SEAB. Many must be very anxious right now awaiting for your results and hoping for the best L1R5 score possible. This will be the time for recognition of all your hard work and positive attitude towards the preparation of this major examination for the last 4-5 years in secondary school.

There will be students that are going to fare very well and lots of joy, but there will also be some that have not done so well in this examinations. No matter which group you belong too - i must add that you still have a long road ahead of you. Stay always Positive and remember there are many options that are available to you after your O Levels. Most important is to consider your aptitude and interests carefully before making a choice.

O Level students these days have more choices and flexibility. With choices galore, how should students decide where to go after the O’s?A good way to start is to find out where their abilities, interests and value systems lie.

Question that i will ask the students will be:
“Is the acadamic path what they have an aptitude for or are interested in? Are they more suited for hands-on, practical courses? Will their personal interests - whether in sports, the arts or other areas - be catered to?”

JCs would suit academically-inclined students who want a more direct path to university. They can also provide a stronger sense of community, as students wear uniforms, are put in smaller classes and are subjected to the culture and ethos of their JC.

Polytechnic education, on the other hand, is valued for its practical nature and relevance to the industry requirements. It is also seen as an increasingly viable route to University. Students from polytechnic benefit from industrial attachments and practical projects which give them the opportunity to apply their knowledge and skills. I can attest to earlier statements for polytechnic education - as i was a product from there and are doing really well. After my O Levels, whereby i scored pretty well and given the choice to join a top-ranking JC - i went for a Diploma course in Singapore Polytechnic. I learnt alot during those days in Polytechnic as well as the 2 industrial attachments (@ Nestle R & D Centre and a Chemical Testing Laboratory in Singapore). After 3 years, I graduated with a Diploma in Chemical Process Technology (with merit) and went on for further education in National University of Singapore for a honours degree course in Applied Chemistry. I must say that the Diploma course in Polytechnic stimulated my mind in Chemistry and thus the Chemical related industry. You can see more in the tab on “about” at the top of this page.

Another alternative for O Level leavers is the ITE, which prides itself on a “hands-on, minds-on, hearts-on” education. It produces 10,000 workforce-ready graduates a year.Some of their courses, such as Digital Audio and Video Production, qualify students for industries where portfolios matter more than academic qualifications. ITE provide opportunities for O-Level school leavers without the five O-levels needed to enrol in polytechnics, but who have the passion, interest and aptitude for such training.

The Key to making the right post O-Levels choice is to ask questions and be active in exploring options. All students should take the time to do research, ask questions, go to open houses…so they can check which avenue affords them the best opportunity to develop themselves in the way they want.
