*frown at the thought of that.. atrocious ultraviolet thing* that was better than the nylon thing though (this is very much related to chemistry *nods*) skim milk + raspberry + homebrand lemonade + some sort of unknown vanilla scented alkanol.. I didn't know you can make a polymer like that :p

I can remember being dizzy :p

If that's what you got then that's what you got :) I must add that it is indeed a bit odd to have a 0.75M acid titrating against a 0.1M base because you will only need about 3.2mL for 25mL of NaOH :) Care to post your results up?

lol.. yes I was lazy ;) I'm not sure if you have met entropy before (it's not in the HSC syllabus but you *might* have come across it in your readings) but here it goes: The "rubber molecules" (long chain polymeric hydrocarbons with smal branches) can order themselves differently at given...

Don't panic :) (Corny may I sound) it's not the outcome that matters! You must go and "have fun" because it's a very good experience.. Besides, you've already paid for it, at least you must go and waste some of the chemicals you've paid for and watch pretty colour changes ;) I'm pretty...

Hello there :) I assume you were talking about the electrolysis of NaCl solution.. as opposed to the electrolysis of NaCl - simply bcause the electrolysis of NaCl is quite dangerous, first of all, the melting point of NaCl is ~800oC and if I remember correctly a normal bunsen flame only goes up...

umm.. what can I say? I guess Jumbo Cactuar summed it up for me :D but I must add that you're a.. bumhole joey :p that's a complement xD I think.. but it suits you one way or the other ;) *waves at the person who posted above me* Finally get a chance to say hi to you without spamming...

:confused: Wouldn't the aim just be: Determining the concentration of [insert name of dilute acid] using [insert name of the standardised titrant]

hey y'all I need some help!!!. my school is soon going to have a prac assessment based on The Acidic Environment and The Production of Materials. Does anyone out there have any ideas? Thanks heaps I think that should help you a lot.. not to mention only the spelling mistakes have been...

What you use is Molymod :p They're cute xD althought I have trouble finding them because people don't seem to sell them anymore *frown* you school must have some :p they're made in England I think ;) I remember having a practical assessment in which we had to make a few molecules with them...

CaCl2 is a dehydrating agent, meaning that it removes water formed during esterification: recall that esterification involves an acid reacting with an alcohol, and a water molecule is evolved when each unit of alcohol reacts with each uni of acid, and CaCl2 is used to remove the water in your...

Is it just me or do you feel it too? This year's HSCers don't seem to be too enthusiastic about Chemistry :confused: maybe it's the holiday.. (it wasn't much better before the holiday though..

nooooooooooo.. :( I'll delete mine too if you delete yours :( and Casmira can answer the question..

omg :confused: this always happens to me :p but I had one more than dreamy :p

I found this in the Oxford Dictionary of Science: Cuprite: Cu2O Azurite: 2CuCO3.Cu(OH)2 Chalcopyrite: CuFeS2 Malacite: CuCO3.Cu(OH)2 coincidentially they have got 4 of them xD just as many as you need.. information on these ores should be readily available, but I don't think you really...

umm.. I'm studying hard to keep up with Chem :p and I'll be staying for quite a while.. or so it seems ^_________^ anyways.. you neeeeed confidence :p go on, yell "HSC occidebis!" a few times and you'll be fine :) it feels like you're going to do great anyway ;)

Hmm.. People obviously don't read before posting.. I wonder why O_____o..

that looks just fine (I tend to say put inter- or intra- before molecular though, molecular is kinda obscure to me, I actually had to read it three times :p but I guess it does imply intramolecular) ^_________^ hey slidy, what did you mean by when you actually knew some chemistry? I remember...

Sounds nice to me :) doesn't "breaking intramolecular bonds" sound like.. breaking intramolecular bonds to you? :p but then again, not everyone is a hardcore chemist ;) I was bored and did a google search for "breaking intramolecular bonds" and "overcoming intramolecular force"/"overcoming...

:p very picky.. *phew* I seem to be safe this time :) didn't say anything of that sort xD hmm.. just out of curiosity :) how would you say "breaking intramolecular bonds?"
