i still reckon is qualatative cause u only observing with out measuring. cause for example observing, u see one piece of shit. u turn around and u saw 2 piece of shit. of course u know that 2 piece of shit is more than one... lol prob not that good an example.

he is a mad teacher. his students are lucky wondering if u know mr singh. his our chem teacher. well he is also indian...

i did not see the important of knowing this until i saw a discussion saying its vitally important. so can some one using words describe the structure of cellulose. and also describe its bonding and stuff. and also compare these with the structure and bonding of sacrose, starch and stuff...

no. thats qualitative. but the question generally ask u to write out an experiment to test the rate of corrosion for different metals or for alloys or for under different solutions. so by saying that u saw more rust on the iron nail is enough to justify that iron is the most likely to corrode.

but thats only qualitative. but the question don;t ask u either way. so i guess qualitative is fine and save ink.

i was reading that and imagining the pages up on pages of answers u write for a question and thought how could u possibly leave anything out. seem like u pour all ur chemical knowledge out on to paper in a 3hr chem exam.

i think they have a question on the experiment you do on different rates of corrosion every year for shipwrecks

i know. never said it wasn;t though... well kinda did. well u can do quantative measurement.

helper will you be online tomorrow on BOS the whole day like today, or u got to teach ur students?

i was refering to in solution form. cause its a weak acid one some of the first H ions ionise while almost all of the 2nd H ion stay intact. But if in neutralisation the first H ion will neutralise while the HSO3- is amphiprotic so it will move to produce more acid. but thats the same for all...

thanks, i am getting the hang of it.

lol 10 char

well didn't think of that. i was more thinking that its reduction potential is too high.

thats when u take the metal out of the solution u are suppose to clean it and dry it. than weigh it. That give u mass loss. cause just by evaporating the water other ions could be left in there and also Fe and Zn ions are soluble in solution.

there is no 2H+ the first H dissociate cause its a kinda strong acid, but the second H does not, and its just HSO3(-). and thats amphiprotic, but slightly acidic. so prob have to say it doesn;t generate SO2 gas.

helper have u got any example with question preferrably assess or evaluate with answer that has underlined important words.

the right hand rule give u direction of movement of current. by using left hand u find the direction of the electron movement. but its the same but at the same time different rule. to find out electron movement use the right hand rule but point in the direction of the force created by lenz;s law

i say ethanol and esters. or alkane and alkanols and alkanoic acids

they not the same. for the generation and emf still just use right. but this has to be done in the direction of lenz's law.

chem is mad love chem Chem>phy>>eco>math>eng
