Chemistry - August 2006

How can a person find out if persons are pressurising water pipes to force chemical based substances in through the pipes to make families sick? How possible is it to do this? As we know a family that is possibly having this done to them. These are legitimate questions and not paranoia, who can we turn to with authority that will not destroy the family for asking? Also this family we know of has a gas hot water system under their house and their are possibly people squirting something in the top of the hot water system so that when it ignites quite toxic vapours are forced up through the floorboards to make the young children and the parents sick. Please can someone help with advice and serious repliers only.

What is the [H+] in a 4M solution of butanoic acid, where the Ka of butanoic acid is 1.48 x 10^-5? Butanoic acid partially dissociates forming an equilibrium:

H(C4H7O2) <-> C4H7O2- + H+

How is this problem done?

Can anyone suggest a method for the determination of 85% pine oil in a commercial cleaner? I originally put a 500 gram sample on a rotoevaporater only to retrive erroneous results ,which I belived were due to the tallow present in the solution. Therefore, I think if I can extract the tallow from the solution prior to evaporation, I can achive a correct representation of the turpine in question. But I am afraid that finding a method is a bit dauting.Please any ideas?? where I can locate a usable method?? thanks to all who answer!

when they are correct. It takes some time to type out all these stoichiometric problem answers. And all of my answers have been correct, while many incorrect answers are being given best answer. Are you being ungrateful or just looking to cheat. I'm going to stop answering your chem questions if you will not award me best answer points.

Any reaction would do, as long as it works. Don't forget to mention catalysts or reaction environment.
