12) its tertiary for both bcz only the most complex of structure is altered and that too just a bit... the basic structure of the protein remains unchanged. just the shape changes (tertiary structure) so that it does not fit. -

5) find out how many division of the eye piece make up one on the stage micrometer in this diagram there are 40 divisions of eyepiece for 1 division of micrometr now the chloroplast in the plant cell is 5 divisions of eye piece... 1 of eyepipece = 1/40 of stage micrometer so 5 of eyepice make... -

sorry i couldnt get to u in time. but for what its worth no you are not supposed to know the values. just see a diagram for the trend of electronegativity on the priodic table on the internet or better yet consult ur teacher to guide u a bit :)- daredevil

no no its no bother. look the Cl dont have to cancel each other. they have to cancel the element on the other side i.e. O Cl and O have a lesser electronegative diff while H and O have a greater electronegativity diff. the Cl being on one side of the molecule dont cance each other. they have...- daredevil

never mind i got it :P ok it is D bcz c in a closed pipe the smalest frequency possible is f. note that on an open end there is always an antinode and on a cosed one there is always a node. so if there is an antinode on the open end of X and a subsequent node on the closed end the frequency is f... -

i didn't say we definitely need Hess for all the enthalpy changes but it is always possible to solve these questions with Hess if nothing else works. it is just a method. and one that applies to all so that makes it handy if u have a good grip on Hess's law u don't need to work with other... -

look Ca2+ needs 2(-1) to balance it out ryt?? if we take two of ethanoic acids it gives us C4H6O4 if we take 2 butanedoic acid it gives us something with eight C and with mmethypropanadoic acid is the same case... only ethanoic acid gives the correct formula. remember to use 2 acids not 1 to... -
