it's correct.Nononononono.....lol I put Fe2O3.2H20
because it was hydrous but I think Im wrong
i rote B bcoz lose of electrons.....hope its correctif u hav 2 eyes then u must have seen tht there were bubbles Around A so "A" RUSTED BUT U R ALSO CORRECT ABT "B"..............HOPE BOTH OV them ARE CORRECT.......if the reasons stated are correct !!!!!!!!!!!!!!!!!!!!!!
my ratio was 1:1.5:1Guyzz i wrote it FeO2.H2O because i got the mole ratio 1:2:1 - what do u think?
yes, that's what we learntit is A because even though it was a chemical cell, the positive electrode is the anode and anode is always where oxidation occurs
exactlyi rote B bcoz lose of electrons.....hope its correct
the ratio and the formula were for 1 mark?it's correct.
that's what i did.
i think they were for 2 marks.the ratio and the formula were for 1 mark?
ummm u shud always right whole numbers so the ratio is 2:3:2my ratio was 1:1.5:1
so is my answer wrong?ummm u shud always right whole numbers so the ratio is 2:3:2
substitution (photochemical)photochemical
ik my answers are wrong, but this is what I wrote:Guyz i think it is B because of electron flow in the circuit !!!
But what about the question that ask about the measurements needed to be taken t calculate the rate of rusting ???
i rote time taken for reactionGuyz i think it is B because of electron flow in the circuit !!!
But what about the question that ask about the measurements needed to be taken t calculate the rate of rusting ???
well probably cuz i remeber doing like u in a school exam and i got it wrong! what dd u write for the formula?so is my answer wrong?
Yesthe ratio and the formula were for 1 mark?
i wrote change in mass/ time taken and yes ratios shud be in whole numbers. but i want to ask u a question did it ask for state symbols in ionic formula? and do i get it wrong if i wrote 2Ag++2Cl-=2AgCl, multipled all by 2 for some reason :/ik my answers are wrong, but this is what I wrote:
the time taken for the rusting take place.(increase in mass of the electrode)
the thickness of the electrode
well probably cuz i remeber doing like u in a school exam and i got it wrong! what dd u write for the formula?
RIGHT
Fe2O3.2H2O
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
