But since when does oxidation occur at anode?!?!

The electrons flow from cathode to anode, and since oxidation is loss of electrons, oxidation always takes place at the cathode not anode.....

let's not fight, k?!
but i have the book right infront of me, and it says anode-oxidation

 

[sma786]

bt CaO is also insoluble

its slighty soluble

Nonononon I never tried to fight I was just confused and wanted to know what the right answer was
Im kinda bad at english so sry if it seemed like I was fighting....

sodium, potassium, ammonium and calcium oxides and hydroxides are soluble.

no, it didn't seem like that!
just to make sure nobody loses his or her temper.

dats da state symbol of Ag+ + Cl-= AgCl

that's correct..

Its a his, and dont worry I dont lose my temper that easily XD
Do u remember any other questions?

how about the organic chemistry part?

how about the organic chemistry part?

da ester ws butyl ethanoate

I did good in most of it apart from the draw a polymer from 2 different monomers.... I messed up and drew a polyester without the []n and like forgot to give the second functional group so yeah I lost the 2 marks over there.....

Oragnic chemistry was very straight forward

 

[EpicLol]

da ester ws butyl ethanoate

That is what I got

 

[IGCSE O/L student]

da ester ws butyl ethanoate

yes!

totally! trust me, i finished the paper in 45 minutes

 

[EpicLol]

do u remember what u got for like the table with the titration and neutralisation and the precipitation?

 

[Mohamed123456789]

totally! trust me, i finished the paper in 45 minutes

The paper was much easier than recent years

 

[white rose]

totally! trust me, i finished the paper in 45 minutes

mee too 45 mins

nope! tell me what the question was, the answer will come flowing.

 

[white rose]

true...

 

[IGCSE O/L student]

mee too 45 mins

yyaaaaaaaaaaaaaayyyyyy! high five!
