My professor is really general... In one of her questions she wants us to look at the equilibrium equation for the dissociation of aicd HCl into ions.

Eq=[H][Cl]

& wants to know what an "appopriate value for Ka would be"...

She didn't give us any numbers so I know she is looking for an answer like negative, or really small, or positive & wants us to justify it. But I missed yesterday's lecture & don't understad... Help!!!

I am studying in a 8th grade science class. I got this question thingy that says that this girl got some soap and got tired ofdroping it in the tub. So she went out and bought Ivory soap. I am suppose to write my hypothesis, state the problem and create an experiment. First i have to figure out why Ivory soap floats and not regular soap. Can any one help me on how to find that out and then if you could suggest a way to create a experiment?

I am not sure how to do empitical formulas...
Here is an example: natural magnets (Iodestones) are found to consist of iron and oxygen. If a 5.678-gram sample contains 4.111 grams of iron, what is the empitical formula of this compound?

THe gemstone zircon is composed of zirconium, silicon, and oxygen. If a sample is found to have 49.8% zirconium, 15.3% silicon, and the reaminder oxygen, what is the empirical formula of zircon?

The narcotic drug morphine has the following percent composition: 71.50%carbon, 6.71% hydrogen, 4.91% nitrogen, and 16.82% oxygen. if the molar mass of the morphine is 285.4g/mol, what are the empirical formulas of morphine?

I have a lot more but just some hints on how to do this would be appreciated...
