What's back titration

I mean in terms of knowledge (phonons or incorrect BCS theory which is the dense positive charge one)

Hahahaha that was funny :D Did so much chem today

True. Does anyone know what the HSC wants?

The BCS theory explains superconductivity using Copper pairs. For a superconductor below critical temperature, there is minimal lattice vibrations to allow the formation of cooper pairs. An unimpeded electron influenced by an electric field flows through the crystal, distorting the metal cation...

Yup, thanks!

Can someone post their notes or PM me them on this?? I really struggle with this dot point :/

Ohh nice! Yeah also I find my option (industrial) relates to back to a lot of things learned in the core. :)

open the textbook

Where do you learn this stuff...

a solarcell is a specialised photocell. a photocell in general doesn't involve semiconductors

:(

Too generic for me :P Try this one pulled straight from the syllabus dotpoints that I think a lot of people will lose marks: Describe the structure of cellulose (3)

Alright thanks :)

How many products/polymers do you know? I'm referring to these two dotpoints: - identify ethylene, because of its double bond, is readily transformed into many useful products - identify ethylene as a monomer from which polymers are made I feel like I'm underprepared (only knowing basic 4...

Maybe i should change the verb to identify. I don't think we have to know it but it consists of TiCl3/TiCl4 and a triaklyaluminium e.g. Al(C2H5)3

Describe the composition of a Ziegler-Natta catalyst (2)

Where did you find this? T_T You seem to know a lot more detail than me. I would have just wrote monitor catalyst to ensure ...

@SSH Oh I was talking about this question

Is there a difference between manage vs monitor they want usto pick on? :S
