Exactly. Wow, they've actually made a mistake in a HSC paper? EDIT: Well, perhaps, but the Haber Process wasn't beneficial to only agriculture. Besides, (C) also said industry. I'd say it's a very weird question if that's what they intended to do.

13. The Haber Process for producing ammonia was developed early in the twentieth century. What was the major advantage of its development? (A) A government sold the process to other governments. (B) The inventor sold the process for a great deal of money. (C) It provided a source of...

"Blood samples can also be analysed for genetic markers using a technique called electrophoresis. This technique separates the proteins within blood cells and can provide a genetic profile of the suspect. It has the potential to distinguish between several suspects of the same blood group." -...

Gosh, talk about misinformed teachers. Every single teacher I've talked to said that benzylethene is the correct systematic name. Oh look, phenylethene is also accepted! I'm so glad my beloved Conquering Chem is right after all. *Hugs textbook*

Bit harsh, but that would slap him into reality and make him realise you're really not friend-material.

Forgive me if I'm wrong, but there have been a lot of questions like yours in the past, all of which give of a strong sense of "Look at me! Look at me! Boys won't leave me alone! :(:(:(". Really though, what do you expect us to say other than "be assertive and tell him you don't have time or...

Hey, don't diss Mrs. Depp. She might not be as hot as Kristen, but she managed to convince Willy Wonka himself to marry her. So she ought to be congratulated and avatared by someone.

I don't think the multiple choice are getting harder. You just have to find the best answer out of 4, all of which could be right in some way.

Acid + Base → Salt + Water Since NaOH is a base and sulfurous acid is an acid, how in the world can they produce SO2 gas?

3 natural biopolymers are starch, cellulose, and glycogen. I can't think of 4, but there are two forms of starch - amylose and amylopectin. So if you separate them, then you've got 4.

My point exactly. Except ... maybe phrased differently.

Yeah, remember Ms. Barda said the woman has authority over the man because of her father's financial contribution to their family? Melimoo: I found my own essays! :D But if you don't mind uploading yours...

It can also be called "q", you know, for fun. :confused: Really though I don't know why there are two symbols. That's just the way it is.

Haha. :p Owned. Year 11 is very important if you don't want to cram your butt off througout year 12. If you have a good grasp of the basic concepts, what you learn in year 12 should sink in easily. The earlier you learn stuff, the easier you can take it during your HSC. I learnt mole...

I hope they'll mark easier than our science department. We had a question on galvanic cells, where we needed to label the anode, cathode, electron flow, salt bridge and electrolytes. It was worth 3 marks. Apparently, if you write say Cu(NO3)2 and not write "copper nitrate" next to it, or...

Just about everything you learn in year 11 is applied in HSC Chem. What you don't need is history of metals. The rest are pretty much assumed knowledge. You learn the concepts and terminology in year 11, which are still frequently used in year 12. However, it's probably unnecessary to...

Yeah, 85 sounds about right. Although above 90 would also be reasonable.

Catalytic cracking uses a catalyst - zeolites to break heavy molecular mass fractions of petroleum into lightweight molecules such as ethene and propene. Steam cracking is passing a mixture of alkanes and steam into hot metal coils, completely decomposing everything into short-chain...

Do you still have your essays? Could I please please please look at them? One thing we can be certain about is that we won't need to pretend to be a Stenogramm character.

I have my Chemistry HSC exam on Wednesday, just like you. :)
