What did u write about addition of sodium chloride speeds up rusting
What was the formula of rust last quetion

Fe2O3.2H2O

 

[EpicLol]

Answer this pleaseee

NaCl is the catalyst and its Fe2O3.2H2O

 

[WhizAly]

for what the most dense? Its francium but I put lithium it was 1 mark right?

Yeah

What did u write about addition of sodium chloride speeds up rusting

What was the formula of rust last quetion

It should be increase conductivity so more electrons flow to the electrode.
and it was 2:3:2

Ohh yeah got the formula rite
The NaCl question oh well It was of one marks ritee

dont remember its prbly 1 or 2 marks...

people what was the electron distribution?

[WhizAly]

It was one

well that actually cheered me up thank you

 

[Beedo]

How many marks were for that question ? And will they accept 8 because they said that Vanadium have more than one oxidation state?

just one mark

i got 1:1.5:1 .. i forgot we had to do it like 2:3:2 .. i did 1:2:1 :'(

same

 

[wajeehaz]

i wrote that it would help water to conduct better :s better conductivity :S

same =/

Now wasn't tht the god damn picture which started all this argument........................use this to prove my answer wrong (A) !!!!!!!!!!!!!!!!!!!

U forgot to show the direction of electron flow which is from B to A.....due to the flow its B....

thts wat i dont noe...rest al is the same.............w8 a min...................i am ryt.........screw those who say B is the answer !!!!!!!!!!!!!!!!!

 

[EpicLol]

Does anyone remember for sure which way the electon flow was pointing to?
Like B to A or A to B?
Thx

i don't even remember seeing anything like that!

 

[pk1947]

did u guys actually find 31 eaasy????

lol!

sorta....

thts wat i dont noe...rest al is the same.............w8 a min...................i am ryt.........screw those who say B is the answer !!!!!!!!!!!!!!!!!

why do u think its a when u dont know which way the electrons flow? XD
