I suppose you could call it a reaction flask. Its up to you. The burette and pippette must be thoroughly rinsed with the solution to be used in them or else this would change the number of moles of solution you are measuring out.

No. The anode is always where oxidation occurs, and the cathode is where reduction occurs. What does change, however, is whether teh anode/cathode are positive or negative...

What exactly do you need to know? Also, try http://community.boredofstudies.org/17/chemistry/25844/chemistry-summaries-resources.html and http://community.boredofstudies.org/17/chemistry/105348/your-questions-answered-assistance-resources.html

I think the answer to number (1) is (A) because the other compounds all produce ions which will react with the compounds in the equilibrium reaction. For example HCl produces H+ ions which reacts with water to form H3O+ ions, and this forces the equilibrium to the left because there's more...

Yeah. Thats similar to what I had (I think!) :

For 3, find the cartesian equation of the ball and then sub in the co-ordinates (100, 1) and that should give you the answer. EDIT: I have checked this, it works - use the identity sec2@ = 1 + tan2@ . I'm guessing for the one, a means acceleration. if it is expressed in terms of x then i don't...

hehehe... I find the exam questions quite easy overall, but the selected exam questions that are in the tute book are very hard. Thermodynamics is easily the worst topic, I find i have to spend hours to digest a couple of pages of that stuff in the textbook. Other than that I think its not too...

Yeah. Last year we had just started esters at this stage. We still finished the course...You can always read ahead. A suggestion is to complete the water management part of the third core topic in any free time you get. This section has little chemical understanding and maximum memorisation.

I found out that in actual fact, the reason why HF is a weak acid is much more complicated than it sounds. Really, its beyond HSC chemistry, but if you are interested: http://www.chemguide.co.uk/inorganic/group7/acidityhx.html

Is phys1111 the easier course? I'm doing Phys1131, far out the heat and ideal gas heat capacity stuff is killing me :( Anyway we have our mid sessions on the 29th april. When do you guys have yours?

Just for some trivia: This is an example of the first-member effect. The first member of a each period can be quite different in properties to the other members in that period.

Is it 3! x (3!.6!.4!) ? Also, don't worry too much about probability/permutations/combinations. I never understood it very well either. In the HSC, when they have a probability question, they always have an easy first part, and a hard second part which very few ppl get.

square root

One which is non-spontaneous (i.e. you have to put current into the cell to force the redox reaction to occur). They are used for electrolysis.

Yeah, I agree 3 Unit seems daunting at first and most people do not do extremely well in it for the first few weeks (or even months). As you learn more maths in 2 unit however, 3 unit becomes much easier..So if you want to drop, drop it in year 12. Also don't fret if your marks seem low. Things...

Umm, Every school has a different major project, I'm pretty sure... What's yours about?

lol..algebra is significantly more difficult though, wish it were as easy as this :D

Chemistry is not half as bad as physics in that aspect. The important thing is to buckle down and study hard, and then prepare yourself for when you do real chemistry - at uni :)

Here's a nice easy question Next Question: If f(x) = √x , find f'(x) from first principles.

Maybe u researched the same chemist that just happened to be in the conquering chemisry textbook :p
