Ah okay. Thanks :)

Is Coroneos the only author for MX2 solutions out in the market?

Hello everyone, I just want to ask whether there is any HSC MX2 solutions pre 2000? And also, what books out there provide these solutions? Thanks :)

yes please :)

anyone got a phone call yet?

But in the experiment we did we used NaCl as the solution, and we put graphite and a test metal (Cu/Zn) in the solution but still a potential difference is produced.

Thanks that makes sense :) Another question: what if one of the electrode is inert (e.g. Pt or graphite) and the electrode and the eletrolyte are of different metals (e.g. Zn and Na solution)?

Hi, can someone please explain what is happening if the electrolyte is NaCl? What is the redox reaction happening? How come there is a potential difference? And in a normal galvanic cell with two metal electrolyte, say Zn and Cu and two electrolyte, what will happen if i use something (e.g...

Ahh okay, that makes sense. Thanks :)

when i put in wolfram "r = theta" i geet but if i also restrict theta it gives me

Thanks! The answer has this : But how do u know how to sketch it?

Hi, can someone please help me with the following question: Graph r = theta where r is the distance from 0 and theta is any angle in [-pi < theta <= pi]. Thanks! :)

but if it didnt start at the origin, the displacement from the origin after 2 seconds is different to the distance travelled :confused:

what if it didnt start at the origin?
