yeah... at least i think it will be fine. bcz seriously how wud we know if the examiner will write them on the left or the right side. i wudve written it the more standard way : on the right side. -

see there are total 7 monomers that make up this polypeptide do if ' O ' is an amino acid and ' - ' is a peptide bond: O-O-O-O-O-O-O soo there are six peptide bonds between these amino acids ii) when 1 peptide bond is formed H2O is released right? so if there are 6 peptide bonds formed then... -

Oohh i get ur point now... see they have given us the REDUCTION potential as -1.23 but in this cell O2 is being oxidised so it will be -1.23 instead.... so as 1.23 is larger it will be 1.23-(-0.83) instead :)) got it? -

they have SUBTRACTED the electrons .... showing that the ions will lose electrons. get it?? ummm i don't get wat u r saying about the electrode potential.... uss ka to iss part mein koi kaam nahi tha :o -

yeah thats what i said.. as oxidation shud occur at the positive electrode, reaction 1 will be the answer bcz oxidation is occuring in reaction 1 -
Chemistry: Post your doubts here!
okay... i am NEVER sure of an answer in a levels but wth ... MY THOUGHTS: they are talking about the positive electrode a.k.a the anode. oxidation occurs at the anode. in reaction I Pb is eing oxidised from 0 to +2 In reaction 2, reduction is occuring instead.. Pb goes from +4 to +2 itallion... -

Heyy guyss.... i am a little confused here.... so let's say that u have two hypotheticaal equations... they have the reduction potentials of -0.15 and -1.15 which one of them will be reduced and which will be oxidised?? -

A star did u get the answer to that question?? if not then send me the ms aik daffa just so i can confirm the answer and then see if i can do it... all i could come up with was subtract the leaking rate from the filling rate.. but ajeeb sa ho gaya hai queston kuch O_O` :P -
