its just the way they r.... S8 and P4 are just their simple molecular formulae and u have to remember it... the reasons are not needed in a levels and my teacher was not too keen to answer when i asked -_- -

ooo ryt..... its not about IF it is soluble or not.. its about HOW soluble it is.... correct if i'm wrong and thansk -
Tips to get A* in A'levels
MA that was some great advice!! u must be a great person and student! :) I just wish i had read it wen i started my a levels maybe then i wudn't hav wasted the time i did.... anyways we all should follow this example of yours and shaare our experiences and knowledgge with others as we'll only... -

so why is the answer not C?? if ethanol is polar and ethylethanoate non-polar?? o.O :confused: -

Q. Find the amount of Fe formed when 96 dm3 of CO are made to react with 320 g of Fe2O3 3CO(g) + Fe2O3(s) --> 2Fe(s) + 3CO2 (g) please solve this question for me... i did solve it but then i cudn't get the right answer :cautious: ._. -

what is the answer?? is it A? -
Chemistry: Post your doubts here!
ohhh i'mm sorry!! it will be MgCl2 because ALCl3 is covalent with some ionic character because of the EXTREMELY high charge density. Mg2+ however has a high charge density but is still lower than Al3+ so it is actually an ionic compound but due to the high charge density of Mg2+ the electron... -

yeah thats what i thought.... CN has a triple bond.. that means all three of the N's valence electrons are bonded but 1 electron on C is remaining that is the cyanide ion... so 3 PAIRS of electrons are in bonding. other than that one pair in the s shell of each atom is unbonded. got it?? :) -

i odn't get these answers either... tag me to the answers wen u get them?? ^_^ -

refer to the organic reactions and see the HBr reactions, you'll find one that makes that benzene ring thing in option 1 and of course the halogenoalkane from option 2 .... option 3 however will not be selected because the H in the OH group is not replaced when a reaction happens, this whole... -

what is the answer given in the ms? -
Chemistry: Post your doubts here!
AlCl3 ... its that concept about the charge density of Al being too high that it attains a covalent character by attracting the electrons more towards itself.... if u don't get it them reply and i'll explain in detail :)
