How were the exams?(Edexcel)

[M-H]

fr the 1st mcq...iv forgotten what i chose hehe..bt fr sure it was one outa the 20 or 200..
then i chose the independent variable as distance while the dependent i thot it shud b resistance cz u cant measure lyt intensity so ultimately resistance cz thats what ur gna measure..
then i got the refractiv index as 1.5....n i wrote the graph should pas thru the origin..but tqs got a point..if it duz the refractiv index is zero...really confused abt that...
ok lets discus the 1st q frm sec B...my 1st confusion ther is what was the q askin...one of my friend said it only asked the advantages n disadvantages of n xperiment conducted with beaker thermometer n blah...
as for me..i rote the disadvantages n advantages of both usin a datalogger n doin the xperiment usin a liquid-whatever-method-they-wrote
after i rote my paper i was rly happy bt then after discusin im nt the same...proly a tiny lil dot of getin a lil more than jst 'happy':( :|

[Urich Von Conon]

Very much for you mate. Do not try to cheat.

Nid. Its alright. Drop it.   

[abuyusef]

ya ......we want the unofficial solutions!!!!!!

[Q80BOY]

why are you shouting and demanding unofficial solutions LOL i did the same exam mate .. i got no solutions

And guys it's alright, you can discuss all the Edexcel AS Alternative to Practical papers (Bio, Chem and Phys)

i dont do edexcel but heard that chemistry was hard...especially the mole question!!
was it??

EDEXCEL= DISGRACE

[TwilightBreak]

Hi..sorry im new here..i dont know why the line shouldnt be going thru the origin..for refraction to occur, the incident light should hit the block at angle. if it doesnt hit it at an angle , the no refraction occurs. By the way this qs..? is bcasically yr 10 stuff right? like pure ig.
I wrote that it should pass thru the origin..

NOOOOOO it was easy!!! i mean it was good...and maybe yes the questions seemed prolly scary but u really gta keep ur cool ...they wer prty strait!!
thats what i thot..
n yeh...im positiv the graph in phy shud pas thru origin...
cz its like all graphs that hav a gradient that measures a kinda property..like fr young modulus...they all wil ofcourse giv u a zero if pas thru origin...light duznt bend when the angle is zero...its only the speed that changes...n refractiv index is more like sth that measures hw much bendin -um thats what i think....!!:|

n wat abt the test 4 OH- ions in chem ? :S

N da colour of da starch indicator?

n which flask did u guys use?

n wat were da 4 things on da diagram?

n n n heehehe! dats it i ithink!

n n n heehehe! dats it i ithink!

test frr oh- : add methyl orange(color change: orange to yellow) or phenolphthalein(color change from colorles to pink)

starch color change- blue to white..
standard flask
n 4things-i made only the condenser wt the corct arows of water goin in n comin out
um others nah:( thou they gta b the beaker n...um...duno hehe

[nzpd9]

for test for OH- i put use red litmus paper nd it turns blue .. shouldve put methyl orange or phenolphalein..
Starch indicator goes from blue-black to colourless! not white!
You use a Volumetric Flask to make up the standard solution...
