Chemistry 52? Discussion after 24 hours
Don't worry! I'm sure they'll be more lenient towards the marking procedure. The grade threshold's probably gonna be lowered dramatically. I've done all the past years for P4 and i can assure you the paper wasn't easy. Stay calm =) -

Chemistry 52? Discussion after 24 hours
1. For the anomaly, i said it is caused by a decrease in volume of liquid Y, (as we are only using a very little amount of liquid Y in g) to minimise the anomaly, i suggested increasing the mass of liquid Y used, as that would reduce the percentage error. Many suggested using ice to condense the... -
Chemistry 52? Discussion after 24 hours
The more exothermic the reaction, the more feasible the reaction (as less heat is required for the reaction to proceed to the RHS). This correlates with the Ecell values. The reaction between Zn and Cu2+ is really feasible as Zn is a strong reducing agent, Zn will reduce Cu2+ to Cu metal. That... -

I wrote as Ecell increases, delta H becomes more exothermic -

Hi everyone. This is something which I've prepared and have helped many students, and they actually liked reading these instead of doing the past years. That's because the syllabus has changed, and not many knew which syllabus has been removed. Also it is time consuming, and many preferred to... -

How was Chem P4? 9701/42
20-25 for E i presume. Average is 29 (roughly) my prediction is of course, just a prediction. It may be lower , it may be higher. But i can assure you its not more than 29. -
How was Chem P4? 9701/42
I found the paper moderately hard, but i do understand why many said it's the hardest paper, due to the exposure of many unfamiliar questions. These are the questions (i can't remember them exactly.. these are just guesses from fragments of my classmates' memory!) The questions may not be in... -
How was 9709 Paper 1? All variants! (Oct/Nov)
I think you have to add 1 metre at the end. The answer is 20+ metres i think for both AP and GP. I am not so sure about the solution myself as I had trouble answering that too. I heard the answer was maximum. But i do not know how to do that too!!! For the value of a, i think i just subbed the... -
Ahaha thanks, the same goes to you. (If you're ever stressed ) hah!
