[bluefa1con]

easy paper
pretty awesome
what about you guys

 

[tribianni]

LOVED IT

 

[Manobilly]

Alhamdulillah really good !

 

[ahmed soliman]

which electrode will be oxidised A or B ?
i wrote B because of the electron flow

 

[shalala]

which electrode will be oxidised A or B ?
i wrote B because of the electron flow

I wrote B too
what did you write for the oxidant and oxidation?

 

[Saadiya Ahmed]

Which metal ion reacts with zinc?...i wrote copper

 

[Naser Al-Ayyoub]

Which metal ion reacts with zinc?...i wrote copper

copper and the one beneath it.

 

[bluefa1con]

B will be oxidized since it is the negative terminal so losing electron

 

[Naser Al-Ayyoub]

which electrode will be oxidised A or B ?
i wrote B because of the electron flow

the smartest kid in my class said it is A
but though i think you are right,
but it seems to me that both do

 

[Saadiya Ahmed]

copper and the one beneath it.

They'd asked for jst one, isn't it?!

 

[bluefa1con]

copper and the one beneath it.

right answer

 

[Naser Al-Ayyoub]

They'd asked for jst one, isn't it?!

no wich metals
ofcourse you have to choose all of them no exceptions

 

[bluefa1con]

the smartest kid in my class said it is A
but though i think you are right,
but it seems to me that both do

you dont always believe the smartest guy
people often screw up
answer should be B bcz on A redox reaction is happening
on B electrons are lost

 

[Naser Al-Ayyoub]

how is it over all, i loved the first question but the second was bad

 

[Saadiya Ahmed]

the smartest kid in my class said it is A
but though i think you are right,
but it seems to me that both do

Yeah some ppl have written A because the O2- ion was gaining electrons from it.
But the arrow shows the net electron flow and tht's why it's B

 

[Naser Al-Ayyoub]

you dont always believe the smartest guy

on B electrons are lost

true but i think both do actually
A gets rusted, and so smaller
B loses electrons as it gives them to A

 

[Naser Al-Ayyoub]

Yeah some ppl have written A because the O2- ion was gaining electrons from it.
But the arrow shows the net electron flow and tht's why it's B

Both possibly

 

[Ophéa]

i said it was A, i thought the anode meant a loss of electrons

 

[reya]

I wrote B too
what did you write for the oxidant and oxidation?

I wrote A

 

[Naser Al-Ayyoub]

what was the formula for stoichiometry
