Question
A solution containing 5 mL of each 4 M acetone, 1 M HCl, and 0.005M iodine is mixed with 10 mL of water.
What is the molarity of acetone in the reaction mixture? (Hint: what is the original concentration and what is the dilution factor)
How could you double the molarity of acetone in the reaction mixture, using the solutions above, and keeping the total volume the same (25 mL)?
Why is it necessary to keep the total volume of the reagents constant after mixing in all
kinetic runs?
List four factors that affect the rate of chemical reactions.
Nitrogen monoxide reacts with chlorine according to the equation
2 NO(g) + Cl2(g) ? 2 NOCl(g)

Explanation / Answer
2. it is a simple process with two steps
(1) removal of water (by decantation from bottom)
(2) addition of acetone
with given densities it is possible also.
And I don't think it is also possible to synthesize acetone by a chemical reaction in the given mixture by adding any other reactants.
