#159829 Chemistry HL Papers 1 + 2 TZ1

Paper 1 was OK, I guess, but as always there were some very tricky questions, so I just ended up guessing some of the answers. Paper 2, though was much better. I also liked section B a lot; I did questions 5 and 7. For the one where you had to calculate the enthalpy change of the reaction, you had to construct a very weird enthalpy cycle where you put the formation of each of the two silicon compounds and the combustion of hydrogen gas to form water. Then, you just had to apply Hess' Law using the data from the cycle. It took me about 20 minutes to figure it out, but in the end I managed to do it.

I did 5 and 7 as well!  I was going to do #6... I don't know why I decided against it.

Do you remember your answer for the energy cycle? I think I got -5520 kj/mol or something... unless I'm thinking of a different question.  I rushed it, so I'm worried I did something wrong.

The question that's been bothering me was the question about local and global pollutants.... I know it probably sounds dumb but I didn't know what to put, so I just made some answer up. What did everyone here put for that question?

  I actually liked paper 1 more. There were some questions where I had to think a little longer, but nothing that made me panic. Both were ok... but I have to say that 2011 and 2009 exams were much easier!
When I first opened up paper 2, I panicked and got stuck on the first question. So I started with the organic question I believe and eventually figured out all the other questions.

Which one was the lead battery? I remember the lead compound question though, the one where lead was added to gasoline (I think it was question 2 on section A). I had no problem coming up with an empirical formula or reaction for it, but I blanked on the molecular formula. I said it was just the same as the empirical, although I doubt it. Did anyone get a definitive answer for that?
I got the same molecular and empirical formula: PbC8H20... because it's a one to one mole ratio between the compound and PbO2... right?

#155706 Final Words to May '12 Candidates

Posted Trololol Marf on Apr 08, 2012 - 02:14

There's less than a month left until we're finished, and at this point I'd like to offer and extend my congratulations to those who've made it this far. And I can say I've had it only more or less as bad as you have. I hope you have taken some time to congratulate yourselves, but not too much! The end of our perilous journey is near, but no less challenging.

We've braved through things we thought were hell, done things that didn't make sense, and stayed up those nights that we thought we didn't. Worked like hell, swore through assignments, petrified by unconverted marks, bled through each page of an A1 reading we detested. But no, you didn't let that keep you down; you have trekked through things that you would never have even thought of doing, and have even written a goddamn CAS reflection on it sometimes too!

The sweet taste of freedom is just around the corner, all we have to do is just do what we've been doing for around 20 months or so- (I don't know what you do, but somehow, I've been doing something [probably die a little bit each day] so that I haven't dropped out yet, so just keep doing it!) You have felt how amazing it is from finishing a math portfolio to completing your last science IA; now that will pale in comparison when you finish that last exam! Most of us are probably hyped for post secondary, whether it's apprenticeship, college, university, travel, whatever. These crap-filled exams are the last things in our way; finally, it's time to show these IB examiners (from hell) what we're made of of what we're made!

Hopefully, you've started to make time to study. If you haven't, (like me) then I hope you're meeting your goals then! Anything worth doing is worth doing well ;) The day where we stagger out of the classroom, finishing our last exam, laughing, half crying hysterically, unbelievably accepting the end is nigh. These are our last days; even I can't believe it; it's really going to be all over.

When exam session comes, I encourage everyone to get some sleep the day before and have some protein; and try not to cram! Try not to put any pressure on yourself, and don't compare yourself to anyone else! You can only do the best you can; don't expect more from yourself that way. By the end you'll be so happy you'd want to punch a baby feel like you've conquered everything! Great things happen to great people! As the IB chapter of your life begins to close, a new, awaits you in the next. I hope things will get better for everyone from here!

You should be proud of your accomplishments. I hope the IBS community has served you well. We are always welcoming  alumni to help out the fresh new-born dying souls who've been conscripted into the IB programme -just like you have- and give them a hand!

Good luck everyone! :)

Wow im one of the few people who hates english, though this is not suprising as IB is heavily english based an does require a lot of bull****ting.

well i like math

dude if your failing math sl, and getting 17%, then clearly you're not cut out for the ib. go and aim for like wabash college instead of the ivy league.

#81220 Whats the difference between A2, B and Ab Initio

Posted Daedalus on Sep 27, 2010 - 05:52

Yeah the above poster is correct... in order of difficulty:

Language A1 (strongest language)
Language A2 (strong second language)
Language B (weak second/strong third language)
Language ab initio (unknown language)

There's no such language as AB :punish: but it's confusing enough having one called ab initio (which is from Latin and does mean "from the beginning"). Some people think ab initio is the hardest, because you have to reach a pretty respectable level and are starting from nothing, but it depends - ab initio Spanish after doing French A2 is easy, whereas ab initio Japanese is not.

#80244 Does God exist?

Posted baja on Sep 17, 2010 - 05:58

God exists. The Tradition of the moon and the tradition of sun gives you clear proofs. You cant see god. But you can feel the power. God can be anything. He can come infront of u as a small kid asking you a question which made you stop and turn back while walking and suddenly a car crashes infront of you. You have been saved by that little boy.
Regards

#80230 Does God exist?

That’s  what you think, I personally see that,  some day, I am going to teach my child these  kinds of beliefs early in his life, and I know for sure, that he will come across à lot of cases in his life, which will justify for him the things I taught him to believe. If I leave my child with no teaching of such beliefs, he’s going to find it very hard to even notice anything about these cases or even think they mean à thing.
My father for example taught me these things since early childhood, yet he NEVER made me believe them, I grew up, and I started seeing these..incidents in front of me or whatever, and I deduced and justified the things he taught me. Even then, he didn’t tell me “SEE? I TOLD you”..Now almost everything I believe are things I came to justify from my life experiences. I wasn’t blindly told to believe in these things.

But don't you think though that that's exactly what the previous user just described? That what you're told becomes your reality? I mean, why do Christian people have Christian children and not Muslim or Hindu or whatever kids? If it's not because that's what their mum and dad tell them so they interpret the world in light of the information they've received from their parents (or other significant people), I can't think what it might be. I interpret the world in light of what my parents told me, and my friends do too. My Muslim friends had Muslim parents who told them all that kind of thing, my Christian friends had Christian parents etc. Nobody forces belief, but it happens nonetheless that we adapt to our environment and take on board what we're told. I even believed my parents when they told me that raisins were dried out dead flies. If enough significant people in my life had repeated that to me (and also if I were incapable of carrying out a practical test...), I'd believe it to this day. I would definitely not eat raisins.
I honestly think that the number of people with religion would be extremely low (perhaps non existant) if it weren't for this indoctrination by relatives, friends and society. And by indoctrination I'm not saying it's forcible or evil, but that it's passive, subtle and it happens, just like all other ideas get diffused to us. The evidence seems to be that if it doesn't happen to people, they don't bother with religion. Just like 5 year olds with nicer parents than mine love to eat raisins.

Also I read a book about the evolution of science (incidentally called The Weighing Of The Soul) and some guy named Rumsford, after some faulty starts which failed to account for convection, experimentally proved and concluded that the 'mysterious' weight loss was due to heat. There remains, to my knowledge, no physical evidence of a soul (unless you decide that it's the brain).

#79514 Is CAS just basically Community Service?

Posted Grumps on Sep 10, 2010 - 03:55

It's basically a way for IB to take up MORE of your time with pointless **** without bloating their already questionable large homework and Z Block hours.

#74754 Hardest topics in Math, Bio & Chem HL?

Posted x___x on Aug 09, 2010 - 13:02

Math HL. Hardest topic? well, I guest the hardest one was probably probability and statistics

Perhaps that was because we didn't get enough practice, and although that topic was new to all of us, IB students, the teacher didn't devote enough time to cover it. We ran out of time, and couldn't really cover the details.
Above that, there are lots of new concepts to be introduced in that topic in particular.
Another hard topic? Vectors, without any doubt! Not the basic concept, but when the topic goes deeper and becomes 3 dimensional, God helps you!

That's what I think. I would like to hear what other people think :P


Biology HL: This subject is fairly easy if you've got the right teacher and if you study consistently. But there is this topic that is called "Plant science" which is a bit difficult. Whenever I wanted to study that topic, it seemed to me that this topic goes on and on, and never really has an end! The topic is not exactly hard, but it's so strange, since plants have their own ways of doing things, no quite like animals (!!!)
Human physiology is nice and easy, but the muscles subtopic is quite hard. The sliding filament theory and other stuff  :) !

Chemistry HL: Although I really, really liked Organic Chemistry, but to be honest, it wasn't that easy. The problem in organic chemistry, i assume, is that although the explanations of certain phenomena make sense, so do the counter-explanations! Everything make sense there, even if you came up with your own explanation it will still fit! At least that what seemed to me all along when studying for that topic.  :P

Wow tdubthebassist, you have some amazing grades there!

Any tips on how to do so well? :)

You have 2 options

1. Have no social life
2. Be Korean
3. Be Russian enough to bribe people over.

... I choose to be no. 2

* no offence towards Russians and Koreans! I am joking!

#67848 Regretting taking math HL

Posted Nickel_Cadmium on May 08, 2010 - 18:23

Don't listen to any of these whiney people. Math HL is a challenge, but not suicide. About 5-10% of all HL math students worldwide get sevens each year, but this is true for any HL course. If you enjoy math, then you should definitely give it a try. If you like it after a year, you stay, if you don't you can always move down to SL. But if you start in SL, you may always wonder how HL could have been and it is nearly impossible to move up from SL to HL. Plus, colleges and Uni's look very possitively at IB HL math, just because it is so challenging. I would advise you to definitely give it a shot.

Differential calculus is much easier than integral calculus.
