People always say: "Put ahead all your weaknesses first, then feed yourself with your strengths."
(NOT SURE IF THAT WAS REALLY WHAT PEOPLE ALWAYS SAY OR NOT, BUT IT DOESN'T MATTER BECAUSE IT SOUNDS NICE!)
Weaknesses in Chemistry
1) I think I'm in deep shit because I still don't understand the combustion data. CxHy(g) + (x+y/4)O2(g) -> xCO2(g) + y/2H2O(l)
EVEN AFTER READING FOR A ZILLION TIMES, I STILL DON'T GET IT, THAT'S WHY I GOT STUCK IN A LOT OF QUESTIONS IN THE PREVIOUS ASSIGNMENTS. IT'S HOLDING ME UP AND CAUSING ME TO HAND IN MY ASSIGNMENTS LATE. SOS I NEED HELPPPPP!!!!
2) I get demoralised very quickly (even in any other subjects) when I don't get the topic that we're learning. And I'm quite weak in self-learning so the next chapter might be quite a hassle for me. Nevertheless, I'll try!
3) I procrastinate a lot. Last Friday, I actually had the intention to blog right after I reach home from hockey. But in the end, I decided to do something else. And now, I'm blogging a week's work in a day. I need treatment.
Strengths in Chemistry
1) I have always thought that my calculation was very good. Used to get full marks during sec sch and all but then as mentioned, I got stuck on the combustion data formula thingy and that holds me back!
2) I am ok when it comes to balancing equations but I think I take quite some time to balance it. I prefer not to rush. Rush = more mistakes!
3) My love and interest for science helps me stand strong and persevere. Although I prefer Physics more, I know that chemistry is also needed and is part of our daily lives. Therefore, I want to do good in both sectors :)

Hi Dian,
ReplyDeleteThe combustion equation is based on the key idea of mass conservation: The number of atoms on the LHS = RHS.
As the reactants and products (with exception of water) are in gaseous state, we could use the concept that volume is proportional to amount (mole) to find the mole ratio. Assumption is that the volumes are measured at the same pressure and temperature.
The purpose of the questions usually involve using mole ratios.
You might need to have a reference book with worked examples. Please visit the school library and look for textbooks that have such chemistry problems.
Cheers,
Ms Jee
Alright I got it now! Thanks :)
