Year End Miri Trip
Year End Miri Trip Felix had lots of fun at his cousin's indoor playground. The children are 2-6 years old, literally 1 every year. Having them all in the car together is a rare event. We visited The Nest, a new stylist cafe in a atas area of Miri. The food there was quite alright, it's pricey in ringgit but cheap in sing dollars. How was your year end holidays? Was it a time of reflection and planning for the new year? Here's wishing everyone a happy new year! Back to Home of Best Chemistry Tuition ...

2020 Class Schedule
2020 Class Schedule 2020 Class Schedule: Our chemistry tuition class schedule for the new year is up 🙂 JC 2 students: Do you struggle with Chemistry in JC 1 or feel that you have not fully grasped all the important foundation concepts? Did poorly for your Promos and want to start scoring As and Bs for your tests? JC 1 students: Realised that you don't understand Chemical Bonding, Thermochemistry and Reaction Kinetics? Can't do gases calculations or don't understand chemical equilibrium questions? How to tell if a reaction is a redox reaction? The fact is, a lot more is demanded from JC students but not many students adapted quickly enough. The jump in content required from O level Pure Chemistry ...

Reaction Kinetics
Reaction Kinetics Reaction Kinetics - A team of scientists at Harvard university have built an apparatus which can achieve ultra cold temperatures. This allows them to capture reaction mechanisms previously elusive as they occur too quickly. "Now, they not only performed the coldest reaction yet, they discovered their new apparatus can do something even they did not predict. In such intense cold -- 500 nanokelvin or just a few millionths of a degree above absolute zero -- their molecules slowed to such glacial speeds, Ni and her team could see something no one has been able to see before: the moment when two molecules meet to form two new molecules." Source: https://www.sciencedaily.com/releases/2019/11/191128172339.htm Wow! Scientists are able to actually replicate such ...

Preparations for A level
Preparations for A level This seems like a pretty odd time to be advocating students to start preparing for their A levels next Nov. However, winter time is always the best time to prepare for a major expedition. In this time, almost everyone is flying overseas for holidays, we need to start our preparations. What do we need to prepare for? Clarification of doubts for J1 topics as most of them will not be revisited until late in Sept when we are revising for prelims. Even then at that crucial period, there will not be enough time to correct all the misconceptions in the foundation topics. For your information, the pace of lectures will be 1.5 times faster in J2 ...

MCQ Answers for 2019 H2 Chemistry Paper 1
MCQ answers B C B C C A D B D D A B D D D A B A A D D C A C B B C C B B The standard for this MCQ paper is pretty easy, there wasn't really any trick questions or questions which are ambiguous. IMO. Only the last question will take a bit longer to calculate, but you should have plenty of buffer from the easy organic questions earlier. Weightage of Paper 1 is 15% so each question is worth 0.5%. Accounting for careless mistakes, most students should score  more than 24 to have a decent chance to score distinction. If you found this useful, do share this with your friends using ...

Nomenclature of anions
Nomenclature of anions One of the common questions that pops up from time to time is how do i write the formula of sodium nitrite? And what's the difference between sodium nitrite and sodium nitrate? Or sodium nitride? This has to do with the nomenclature of anions. The convention for naming anions is as follows: -ide ending is for a monoatomic anion of an element. e.g. hydride, fluoride, oxide, sulfide, nitride, phosphide etc. -ite ending is for polyatomic anions containing oxygen, oxyanions. -ite is for the one with less oxygen atoms. eg, nitrite, sulfite -ate ending is for polyatomic anions containing more oxygen atoms. eg nitrate, sulfate If there's a series of 4 oxyanions, hypo prefix refers to the anion ...

Suggest type question
Suggest Type Questions Firstly, suggest type questions took up 12/75 (16%) marks in 2018 paper 2 and ~24/80 (30%) marks in paper 3. So we cannot ignore its importance.  Secondly, most “suggest” questions aren’t totally novel questions, they are just contextual. Meaning we can look at the question and derive the answer from the information provided.  In this article, I wish to highlight some ways to think about how to approach such questions. Please refer to the 2018 paper when reading through this document, it will give you some context. Some simple general questions What is the difference between A & B? Is this linked to the earlier parts of the qn? What is the direction/flow of the qn? Why ...
