chemistry and physics 31,33,34

chemistry
p 31=
energetics nd salt analysis
p33=no titration+energetics+5 salts
p34=enthalpy change,impurity,cation anion,for enthaly sumthin 2 do wid na2co3and nahco3,for cation sulphur copper chromium mg..

physics
p 31=electricity big question+pendulum.
p33=oil viscosity and diode.
p34=oscillatiions wid glass prism.sumthing wid magnet.

 

[TravisMcDee]

chemistry p31 , aldehyde vs ketone test also ...

 

[tabz]

Is there no titration for P31 aswell?

 

[moeedghaffar]

yup.most prob no titration..

 

[Syed.Mazahir.Rizvi]

any orgainc in 34????

 

[moeedghaffar]

i guess no organic.
but im not sure.

 

[tricky]

wat do v need to do with DIODE IN PHY P33??xplain it plzz i have to get an A in it as i messed up in p1....

 

[moeedghaffar]

in a diode dere actually a LED nd a LDR.
ull have 2 measure change in resistance with different light intensities.
u vary the light intensity by using a thin sheet of scraping ppr placing it btween the tube which contains LED at one end and LDR at the other end..

 

[tricky]

is it a paper 33??i heard in p33 there is no LDR OR LED???:S am confused....

 

[honlee91]

wat is oscillatiions wid glass prism in physics 34?? can u expain more bout it?? is there any example in the past year paper? i really appreciate it...thx

 

[Glowing light]

paper 34 have something to do with strings and pivot.plus magnet

 

[moeedghaffar]

dere is no questin inn past ppr about prism oscillatins.
but its similar 2 normal oscillatins .u hane a prism insted of a ball this time.

 

[moeedghaffar]

according to me p33 physics will have a question regardind diode and oil viscosity.
honlee=
oscillations r similar to those of ball.ull use a prism instead of ball.that it.

 

[moeedghaffar]

glowing light..
r ur sources authentic?
cuz what i heard was little different.

 

[Glowing light]

idk.. but was i heard is that there is something related 2 power supply and magnet..
and there is a prism, rod, string and weight 4 one question.. not that sure..=s

 

[aleem420]

Can anyone give me a complete details about the apparatus of physics 31 paper ????????????????????????????????????? Wht is in the oil viscosity exp??????????

 

[Glowing light]

and yes in paper 33

we ll be given small glass balls.. and oil in a cylinder.. and we have 2 perform a experiment.. and a a diode 1..

 

[skater92]

can u plz giv mre details abt phy p33 n 34??

 

[skater92]

n also ANYYYYTHNG abt phy n chem p5???!! m really desperate here!

 

[KhajistaNizam]

z organic stuff cumin or nt????
