a chemistry seminar

i attended a boring interesting and useless helpful chemistry seminar which was proudly organized by the infamous and almighty Mr Yow Hoong Kong the other day. (it's a bit late to post this now but i just remembered by coincidence so yeah, at least i remembered right?) it was meant to be 2 1/2 hours but it finished in abt an hour (0.0) coz the Q&A session took abt 10 times shorter than it was supposed to be (thx to mr yow n other chemistry teachers who r teaching form5s this yr) & as much as one-tenth of the hall was occupied (0.0) great right? yeah man. anyway, this is wat i summarized after taking some notes b4 falling in2 sleep in abt 20min (apparently i didn miss anything ^^ ).
1. Definition

this is 1 of the most ridiculous part in the entire paper (even worst than Moral!) bcoz all definitions must follow the txt book letters by letters!!!!!!

2. When they say name, just name

let's say they gave u structural formula of 1,1,1-trichloroethane n asks u to NAME it, dun pandai2 go and give the chemical formula coz salah!! hahaha!! if you gv the name n the formula & both r correct then takda masalah but if any1 of them turned out to be wrong, GG becoz of WCR (Wrong Contradicts Right) so y take the risk? write the name oni la!

3. When they say "describe briefly", describe IN DETAIL!

Reason: you don't wanna lose marks for absolutely no reasons at all!
eg. Q: Test the presence of carbonate ions in sodium carbonate solution
A: 2 cm3 of dilute hydrochloric acid is added into 3 cm3 of sodium carbonate solution in a test tube. effervescence observed is bubbled through limewater in another test tube by using a delivary tube. if carbonate ion is present in the test tube, limewater turns cloudy.

detailed right? no it's brief T_T

4. When asked to calculate 1/t (rate of reaction), give up to 3 decimal points.

5. Essay-Describing an experiment

Include

  • Aim
  • Material n Apparatus
  • Labelled diagram
  • Procedure
  • Tabulation
  • Chemical Equation
  • Safety Precaution

6. Pray

(Pelajar yang bakal menduduki peperiksaan SPM haruslah mengamalkan nilai kepercayaan kepada Tuhan......)

Wishing u all the best of luck for SPM
