The thing i don't get is why are we taking the lost water molecules to be 3, coz when 3 amino acids link, only 2 water molecules are released, not 3, as per my understanding......
This is an extract from the ms for this qn.

Hi soldier!heya tx a million sis, um for part i) though, the answer is G>E>F and part ii) only G reacts with Na2CO3 to produce effervescence
and with NaOH E and G both dissolve.
i kinda reasoned out stuff the same way you did above, but as i mentioned above the ms states otherwise:/
and about the second qn, my exam is tomorrow don't want to bother you, but if it's possible and you can do it today, i'd be really really grateful
tx again
My test is over but yeah i'll definitely tell you if i do need help againHi soldier!
I'm so sorry i couldn't reply you on time because yesterday i had to rush. Still do u need the solutions?
Still if u need help, i'm there!
Methanol is much more toxic than ethanol, what does the toxicity of alcohols depend on ??? Does it depend on, how long the carbon chain is ???
Hi what's the answer, so that i can check if i'm right.Balance this equation using the oxidation number method?
V3+ + I2 + H2O >>> VO2+ + I- + H+
I tried using the method but it kept stumping me, there's one step I seem to be getting wrong. I'd appreciate if someone were to show step by step how to balance it using the oxidation number method,
Thanks!
It's 2V3+ + I2 + 2H2O >>> 2VO2+ + 2I- + 4H+Hi what's the answer, so that i can check if i'm right.
Oh sorry for the confusion it's A not BCan u confirm this A or B?View attachment 19154
I got most of it but, why did you put a 2 next to H2O and how is it an oxidising agent?Hi aalmuhannadi. sorry it took me time to put up explanations. I hope u'll understand in this mess.
Humm... i have put sme indications, follow the numbers.
