Title: Which chemical are you picking?
Post by: Rosie on June 22, 2008, 05:48:04 pm: Just wanted to ask what people are going to choose as a chemical to study for Unit 4:

ammonia
nitric acid
sulfuric acid
ethene

Post by: ed_saifa on June 22, 2008, 05:48:42 pm: Sulfuric acid
Title: Re: Which chemical are you picking?
Post by: Collin Li on June 22, 2008, 06:02:06 pm: Sulfuric acid please!

There'll be more past material on it!

Post by: psychlaw on June 22, 2008, 06:17:38 pm: Umm, what do you do with the chemicals??? Why do you pick just one?? just curious
Title: Re: Which chemical are you picking?
Post by: bec on June 22, 2008, 06:59:48 pm: what is this? is it something our school chooses, or do we pick a chemical individually?
Title: Re: Which chemical are you picking?
Post by: chem-nerd on June 22, 2008, 07:17:21 pm: You have a choice as to which of the four chemicals you study in depth, in particular,
- factors affecting the production including rate and equilibrium position, catalysts, temperature, pressure
- waste management including generation, treatment and reduction
- health and safety
- uses of the selected chemical.

Your teacher will probably choose the one you study in class but that doesnt mean you cant also study one of the others if you prefer.

The questions on the exam will be generic so that they can be answered no matter which chemical you focussed on. For the short answer question you will need to focus on just ONE chemical for the ENTIRE question (eg you cant answer part a and b from sulfuric acid and parts c and d from ethene)

Post by: bucket on June 22, 2008, 08:11:27 pm: did they have qs on sulfuric acid last year?
Title: Re: Which chemical are you picking?
Post by: enwiabe on June 22, 2008, 08:13:36 pm: Sulphuric acid was a big part of the unit 3 course if memory serves. You should find a wealth of questions on it in past papers.

not to my knowledge

from what i've heard, we'll be required to know about the reactions of the particular industrial chemical and their equilibriums and other things [and the questions will be generic]
Title: Re: Which chemical are you picking?
Post by: ganges on June 24, 2008, 11:03:14 pm: Ethene sounds good as well because it played a big role in the organic pathways bit in Unit 3 so we already have prior knowledge of it.

Post by: Matt The Rat on June 25, 2008, 02:18:56 pm: Sulfuric acid

Post by: perfectscore on June 26, 2008, 06:36:00 pm: which are the hardest/easiest?
Title: Re: Which chemical are you picking?
Post by: Rosie on June 28, 2008, 11:43:24 am: yeah, is sulfuric acid easier or is it just because it has alot of past material. It looks hard to me
Title: Re: Which chemical are you picking?
Post by: gfb on June 28, 2008, 11:57:22 am: I have comprehensive notes about sulfuric acid from last year, when I have the chance I'll scan and upload them.

Title: Re: Which chemical are you picking?
Post by: ganges on July 01, 2008, 10:41:26 pm: hmmm, my teachers given us 2 chemicals to research over the holidays, strange. :-\
Title: Re: Which chemical are you picking?
Post by: Collin Li on July 02, 2008, 01:00:49 am: Yes, I have heard of that too. However, that is a misguided strategy, because on the exam you will have the same general question as everyone else, just that the answers differ, depending on your chosen chemical. This makes studying 2 chemicals pointless. The only reason why you'd study 2 detailed studies (in Physics, for example) is because you might get an easier question, but since (according to the sample exam), the question regarding the chemical will be the same, there will be no advantage in having that extra choice.

Also, you cant answer half of the general question with one chemical, and the other half with another chemical. Hence, you should just pick 1 and stick with it.

Post by: dusty_girl1144 on July 13, 2008, 12:04:57 am: we are doing sulphuric acid at my school. and jee the process in making it.... o.O

we arnt doing it purely and simply because unit 3 was BASED nearly on ethene been made to ethyl ethanoate remember? that had an organic pathway question similar on the exam
Title: Re: Which chemical are you picking?
Post by: Collin Li on July 13, 2008, 01:15:19 am: Unit 3 did not talk about the production of ethene. It talked about some of the uses of ethene.

The old course featured a section on Sulfuric acid in Unit 3.

LOL going by what my teach said.... :P
Title: Re: Which chemical are you picking?
Post by: Collin Li on July 13, 2008, 11:11:43 am: Okay, well the "uses of ethene" is part of this unit, if you choose to do ethene. You also need to know the production of ethene though.
Title: Re: Which chemical are you picking?
Post by: ganges on July 13, 2008, 04:17:16 pm: So does anyone know any good websites where i can find information?

Has anyone put any notes on here?

BTW- we can choose SUlphuric OR nh3, not both, sorry. :buck2:

I will choose sulphuric

was that the organic pathway? im going sulphuric acid neway :P so dont have to remember ethene... i hope...

Title: Re: Which chemical are you picking?
Post by: Collin Li on July 27, 2008, 07:37:51 pm: If you can write the chemical formula of your chosen chemical, you win 1 mark on the Sample Exam.

As for me, H2SO4 ftw!
Title: Re: Which chemical are you picking?
Post by: Pandemonium on August 05, 2008, 10:08:35 pm: sulfuric acid because it's easiest.
Title: Re: Which chemical are you picking?

Post by: dusty_girl1144 on September 03, 2008, 02:50:41 pm: ammoinia is gay. it smells like shit.

JOKES :P

thats actually really werid. alot of schools are doing sulphric acid.

maybe that could be an advantage to you???
Title: Re: Which chemical are you picking?
Post by: bucket on September 03, 2008, 04:23:25 pm: we did ammonia

Yumm. I have double chem tomorrow, I might try this!!! I just need to go to bring a block of chocolate because I don't think our science lab stocks it. Thanks Mao, your saving me from waiting in my stupid canteen line.
Title: Re: Which chemical are you picking?
Post by: Pandemonium on September 04, 2008, 04:16:48 pm: why the hell would you bring chocolate? that's a waste of money.
just bring glucose/any other cheap sugar variant.
