Chemistry - November 2006

In my chem lab, we had a solution of 1 drop bleach (5.25% NaOCl) and 1 drop 0.1M HCl. After it reacted for a bit, we added 1 drop of NH3. The question is "explain how this terminates the reaction using words and chemical equations." I think I get the word part (wouldn't the NH3 just neutralize the HCl, and then the NH3 doesn't react with the NaOCl?) but what about the equations?

the cell can burst if the membrane becomes too large


materials cannot enter the cell if it is too large.

the cell may become too large to take in enough food and to remove enough wastes.

waste products cannot leave the cell if it is too small.

I have found the specific gravity of Amyl acetate, it is 0.876g/cm3. I have been asked to make a 0.04%w/v solution of amyl acetate in water. How would i go about doing this since the density is different to water. How exactly would i weigh out the amyl acetate. Please help me out. Thank you.

A reaction known to release 1.78 kj of heat takes place in a calorimeter containing 0.100 L of solution. The temperature rose by 3.65 C. Next, a small piece of calcium carbonate was put in the same container AND 0.100 L of dilute HCl was poured over it. The temperature of the calorimeter rose by 3.57 C. What is the heat released?

Why does the question include stuff like calcium carbonate? Is that going to decompose to CO2 and CaO? and how does more than one reaction taking place affect the answer? How should I go about solving this?

in czech republic naphtha is used as the word for the fuel that we call diesel and yet it seems to me that naphtha is a higher fraction from the distillation process than diesel. i could understand it if diesel came from naphtha but it seems that isn't the case.
