Chemistry P31

[Osmix1995]

the rode is A , because the it is on the anode and also because of the oxygen bubbles , and the mole ratio is 2:3:2 , and V was the answer on both equations it was oxidant because the oxidation number decreased and it gained electrons (it was reduced ) .. and the other one it was oxidised increase in number of oxidation and lost electrons.... the last question the formula is if i remember it was hydrated so it had .2H2O ,,

an

i wrote the same but confused

dd yea about recyclin and burnin did they ask the disadvantages?

 

[reya]

but that was out of 200 not 180

no always paper 1- 40, paper 3-80,paper 6-60 !

 

[BurakBurak]

keep banging your head
A was losing electrons and B was supplying it
so the net loss was from B
much like sacrificial protection
B was being oxidized .
there is no point arguing
read the thread
people are backing up B because it was right

Again wait and see bro

 

[Osmix1995]

in electrochemistry, anode is where oxidation (loss of electron) occurs. Cathode is where reduction (gain of electron) occurs.

i think rod was B as it is a cell B was the anode the negative one and last yea i got Fe2O3.2H2O

Agree in all

As a catalyst

wattttttttttttttttt..................ions r catalysts ..................................it was asking to SUGGEST only !!!!!!!!!!!!!!!!!!!!!

Make it up

 

[shalala]

Agree in all

It was B. B is an anode!!

The Recycling and Burning question

recycling : Advantage it helps reusing the plastic into other good things ( or anything near that)
disadvantage it uses alot of energy and there is running costs of electricity bla bla bla ... (or anything near that)

Burning : Advantage it provides heat energy which can be used to make electricity (heat water and then the steam will drive turbines)
disadvantage it releases harm-full gasses

It was B. B is an anode!!

Fe is changed into Fe+2 it is oxidation

We had to give an advantage and disadvantage? I just gave disadvantages!

Recycling ..............adv. It saves energy and {{{money}}}
..............................disadv...difficult to distinguish b/w different polymers cuz each n everyone of them has to be separated.....adds costs.
Burning.............adv.....avoids sight pollution
.................................disadv.....releases toxic gases
