and for the upcoming chem lec test...
Lecture Test 2
================
This is a repeat announcement.
Date of test: 2 May (Wed)
Reporting time: 7.50 am (No extra time for late comers)
Topics for the test: Periodic Trends in Physical Properties, Ideal
Gases, Chemical Bonding
Format: 14 MCQs [14 marks] & 3 structured questions [16 marks]

Dear all,
Please be reminded that Final PIs are due, LATEST, next Thursday, 3rd May, 4pm.
Check the Question Paper for format, word count and the checklist before you submit your FINAL PI. And attach the COVER PAGE! If you still don't have a cover page, get one from Cara next week. If you've received your cover page, please try not to lose it or to crumple it. Cara doesn't have extras.
So if yours is badly crumpled, photocopy one yourself or bug cara or something..
Yup. Please try your darnest to stick to the deadline because it's the FINAL PI! And it's an A level paper so it's very serious matter. Yes.
Jiayou. All the best,
Your PW rep

hello 6d im here with a few announcements!
please pay timothy $10 for the econs fund! ok according to him we're operating into negative $100 value already and er he claims that nobody wants to pay him. so can we please pay him 10 bucks for the econs fund when we see him? he is pretty unlikely to chase after you for it
secondly the PI deadline for wednesday is only for those who are REDOING their topic. meaning new groundbreaker or entertainment medium. OTHERWISE its compulsory to submit your second draft tomorrow. or if you dont want to submit, that is.
lastly would anyone like to suggest anything for fac outing? outfits and stuff. yup do try to come up with something that fits us homos.

Hello everyone! GP rep here again.. Here are the updates for this coming week! 23rd - 27th April.
Monday : Physics Lecture test
Tuesday/ Wednesday: PI Draft II due.
Wednesday: Compre Test Part I (during GP) (tentative), Physics SPA
Friday: Chemistry Test (uncle Ralph), Maths Timed Assignment, and Compre Test Part I/II (depending if we did Part I on Wednesday.)
By the way, Part I is the all the compre questions, and Part II is the AQ. If we do Part I on friday, then Part II will be next week.
We're gonna have a long week ahead of us! Take the weekend and start gearing up for it! On the flipside, after this week, we can take a deep breath before we hand in our Final PI the following week, and Chemistry spa is only the week after handing in our Final PI.
Time flies when one is
having fun! er.. if stress is considered fun. okay some RANDOM stuff before i go and start physics revision.(oh right. dang.)
Advert of the year, one of two years ago. -.-"
Taken during one of the bowling trips. at CDANS.. Alvin looks damn cute. WHOOPS i DID NOT JUST SAY THAT.

Hail People of Ear... S6D! I come back to you now, at the turn of the tide, to bring you some STARGAZING business.
There is going to be an Astro camp during the June Holiday in Bintan, Indonesia. It will be a 3day-2night camp from 30th May to 1st June. The fee is $140 including transport, lodging, food, and basically everything necessary. The camp will only go ahead if there are 20 ppl joining, we are still short of 5, but anyone who wants to join will be welcome!
You can talk to me if you are interested or you can contact Ady (andy? He's the guy in charge of astro camp... interesting person) directly at 96314568 for more detail.

Hey guys,
Sorry that I forgot to remind youall about the PI draft deadline today. I'll be more responsible next time :/
Anyways, if you haven't submitted your PI draft, please be reminded that the final deadline is tomorrow,
17th April, 9am. Put the
printed copy in her pigeon hole and no emails are allowed.
Yupyup. And remember to hand in all future stuff on time!
Yay, that's all.

In view of the coming of SPAstic activities, please note the following to ensure success.
Skill B- NEVER EVER fill up burette using a dropper so that you get O cm3
- NEVER EVER leave your funnel on burette.
- When pipetting and releasing solution into flask, tilt flask, touch the pipette tip GENTLY on the dry side, and roll one time and pull out. NEVER make any clink clink noises.
- SWIRL CONTINUOUSLY, and i mean REALLY CONTINUOUSLY
- DO NOT use the 1.5 drop 180* turn technique, nor the 0.5 drop touch side technique
- USE YOUR WHITE TILE.
- SHAKE your volumetric flask REALLY REALLY well.
- ALL TABLES must have PROPER titles as i have taught you.
- Recording colour change: The solution turned from COLOUR A to COLOUR B; where colour A is the colour JUST before end pt and colour B is THE END PT. (e.g Fe2+ titration, the colour of solution before end was pale yellow although it started out colourless/green, so record Pale Yellow to Pale Orange)
- Skill B discussions MUST BE INCLUDED. +-0.10cm3 MUST MUST BE INCLUDED.
- AT LEAST 2 reasons for consistency. (Rinsing of apparatus NOT ALLOWED)
- At least 1 reason for anomaly.
- Record everything to PROPER D.P.
Skill C
- Please write PROPER mathematical statements. ("No. of moles of HCl" NOT accepted if you referring to different volumes. Write "No. of moles of HCl in 25.0dm3")
- TIDY TIDY TIDY TIDY WORKINGS. Cancelling and blanco NOT encouraged.
- For simplicity ALL answers CONSISTENTLY 3 s.f.
- NEW CHANGE. ALL Ar and Mr now must be in 1 D P and only 1 D P (e.g. 120.0), EVEN WHEN they appear in a working!!!
- Show step by step working, don't skip if possible
- When invoking burette or pipette etc readings, write down to their appropriate d.p. in your calculations! 18.90 must be written, not 18.9. 25.0, not 25. 5.00g, not 5g
- Make sure you know your redox and stoich.
Last of all, you don't have time to dilly dally so do fast and think fast.

1) Decapitate me and all becomes equal. Then truncate me and I become second. Cut me front and back and I become two less than I started.
What am I?
2) I live above a star, and yet I never burn,
I have eleven neighbors, and yet none of them turn,
I am visited in sequence, first, last or in between,
PRS (& sometimes Q) are my initials,
Now, tell me what I mean.
3) A rich merchant had collected many gold coins. He did not want anybody to know about them. One day, his wife asked, "How many gold coins do we have?"
After pausing a moment, he replied, "Well! If I divide the coins into two unequal numbers, then 32 times the difference between the two numbers equals the difference between the squares of the two numbers."
The wife looked puzzled. Can you help the merchant's wife by finding out how many gold coins they have?
if the previous riddles are easy.... try this... 3<2<1 in difficulty

Shermy the Chemmy makes his debut appearance today! *clap clap clap*
Hi I am Shermy the Chemmy, and i'm here to clarify your doubts and take you into the wondrous world of chem! *clap clap clap* Thankew thankew, so shall we go on? Today, we had our final (yay!) lecture on chem bonjing. As many of you raised eyebrows, scratched the head lice of your head, pulled your cheeks till you look like a bulldog in desperation at questions left unanswered during lecture, Shermy the Chemmy hereby presents you: Fun Stuff for Bonding! YAY!
- Why do ionic compounds generally have higher MP than metals?
When an ionic compound is melted, enough electrostatic attractions have to be broken to allow small clumps of ions to slide past each other in a molten state. As electrostatic attractions generally require much energy to break, the MP of ionic compounds is usually high. In metals, the cations are held in a regular arrangement by virtue of electrostatic attractions between the mobile electrons and metals. When a metal melts however, electrostatic attractions are just weakened enough to allow the cations to gain enough kinetic energy to slide past one another, hence melting a metal needs relatively less energy and thus has lower MP than ionic compounds.
- Why does silicon not form discrete molecules for silicon dioxide but carbon does in carbon dioxide?
Silicon is from the next period from carbon and oxygen, thus has one more quantum electron shell, which makes the atom larger. When carbon and oxygen react, the carbon forms a sigma bond with oxygen first. As the 2p orbitals of carbon and oxygen are around the same size and smaller than sulphur, the sigma bond is short enough to allow a side on overlap of another p orbital forming a pi bond. This allows formation of a discrete molecule.
Silicon however, when it reacts with oxygen, it uses its 3p orbital. As the orbital is significantly larger than that of oxygen, the sigma bond is longer than that between carbon and oxygen. The bond length is too long to allow comfortable side on overlap of 3p and 2p orbitals. Moreoever, the different sizes of the 3p and 2p orbitals make formation of a pi bond more difficult. Thus Silicon prefers to form all sigma single bonds with oxygen in an extended structure. FYI carbon dioxide DOES form the giant covalent structure, called carbonia, but it is energetically unfavourable and forms back to normal gas form easily.
- Then, why can sulphur form sulphur dioxide??
Sulphur forms 2 double bonds with 2 oxygen, but didn't we agree that 3p-2p overlap is difficult? It IS difficult but not impossible. For Si, it can easily hybridise 3s and 3p to form sp4 which makes it easy to form 4 sigma bonds of good overlap with oxygen. for sulphur, hybridisation is more complicated as it may need d orbitals, so using pi bonding is more favourable now.
- So why does sulpur form 8-ring molecules but oxygen forms diatomic molecules?
When two period three atoms sigma bond, the bond length is longer than that for a period 3 and a period 2, meaning that an S-S bond is longer than an S-O bond. So after S-S bond is formed, side on overlap of 3p orbitals is even harder to achieve, so might as well save the trouble and use all sigma single bonds to maximise the overlap possible.
- Then why is sulphur 8-ring? Why not 6-ring (like carbon is cyclohexane)?
Sulphur is large, so a 6-ring might pose serious space problems. 8-ring happens then, to be the first arrangement where the spacing of S atoms is far enough to not stress the bond and the bond angles. FYI sulphur does form S7 and S12! S7 is what makes sulphur yellow. So kewl.
- But phosphorus is 4 member molecule! And it is a period 3 too!
This is actually white phosphorus, the least stable phosphorus. Because of the number of bonds phosphorus needs to form, this molecule can exist, but the angle strain due to the size of the atoms make this unstable and highly reactive. White phosphorus burns easily in air.
Red phosphorus, the more stable matchstick form, is in a network arrangment, which means less strain on the bonds, and higher stability.
- Why does carbon dioxide have higher melting point than chlorine gas?
I'm not sure about this. My guess is that carbon dioxide, although held by WEAK LONDON DISPERSION FORCES (not pd-pd. pd-pd needs a polar molecule. my old teacher taught me wrongly )= ), may be more polarisable than chlorine molecule since it is in a longer shape than chlorine, and maybe due to it's polar bonds too. MP(actually Sublimation point) of dry ice is -78*C chlorine is -101.5*C
