When the current is turned on in X, at the start a magnetic field is induced to oppose the increase in voltage, and therefore generate a back EMF, however it will eventually reach a constant voltage as it is a DC circuit and there will eventually be no magnetic field. A similar field will be...

Im probabaly thinking way too much into it, but maybe it wasnt necessarily H2O that was condensed out, as condensation polymerization can refer to the release of any small molecule, not just H2O, maybe it could have been H2 or methanol instead although, but otherwise, all the options on there...

I usually just go and make notes on the whole syllabus, reading over 2-3 textbooks and heaps of internet sources to make sure I get as much knowledge as I can on each topic, then ill read over em a few times then attempt some past papers, I just find it better to learn all the information first...

A, C, C

yeah thats what i thought, literally glanced over it for a second and dismissed A, B & C as all containing CO2 because they were all written similarly, but A did infact CO and D wasnt balanced correctly

the graph also did refer to yield on it, so you could talk about why the yield is balanced with the rate of reaction, which would be influenced by a catalyst, if there is a greater rate from the catalyst, then they could decrease the temperature a bit more to increase yield a bit while still...

seems right to me, 18/20 id get

nah it didnt specify temp and pressure, it just said explain the conditions employed in the haber process with reference to the graph

id say so, pretty sure the question said something about the conditions used in the haber process with reference to the chart, but doesnt mean you have to talk specifically about the stuff on the chart, i just basically talked about everything I knew for the conditions of haber process cus it...

theres a dot point on there about using computer technologies to measure the pH of acidic substances, i suppose they would expect you to be able to transfer this concept over to titrations because its basically the same thing, didnt you ever do an experiment with a ph probe or something?

yeah i talked about rate, catalyst, degradation of equipment due to high pressure and temp, and liquefying the nh3 to increase yeild as well as all the stuff on the graph

it did say discuss so you could have provided reasons why its properties are good and bad for the application, i think they will draw a fair bit of how you related its properties to it use, i think i wrote about 2 properties and 4 or 5 points about its use

yeah i think it might have been, for some reason i remember the question being on its own page, although if that is true i cant remember what was below the one where you had to draw the structure of citric

was out of 4 wasnt it? id say if you wrote our all your formulas and showed the substitution and all your calculations were correct with the formula you used, youd probably get 2, maybe 3 if youre lucky

citric is triprotic fam

>mfw 8 mark question on einstein and planck and their views on whether science is removed from political and social factors

Conquering chem textbook had a mad part on the fertiliser experiment, i wrote slowly adding the BaCl to a heated solution of the dissolved fertiliser will produce larger precipitate crystals, this means that there will be less precipitate lost through the filter, also less ions from the solution...

what one?

nah fam, doesnt matter what you put in the burette or flask, you still get the same values either way, the important part of the question was where it said "transfering into another solution", you pipette the solution into an empty flask where as with the burette you are transfering one solution...

i chose burette, the "transfering into a solution of known volume" kinda gave it away
