  1. Thank you very much for your help.
  2. No its was Dilute Cl2. Sorry. Cl2 solution. Ok. thanks anyway. I understadn the principle of it now so its cool.
  3. I have a 2 part question here. First of all we added 1cm^3 light petrolium to 3 test tubes. Then we added 1cm^3 of aqueous chlorine, bromine and iodine solution to each tube respectivly. Then we shake the test tubes to mix the solution. This ended up in the solutions seperating into layers. No prob. The questions are What is light petroleum, and I assume they seperate into layers due to the different denisty. Which is at the top? Has light petoleum got a greater denity than Cl2(aq), Br2(aq) and I2(aq) ?
  4. Thank you very much. I appreciate your imput.
  5. These two have caught me out. One because its a multiplication of absolute values and the other because its a a graph, but... Numbers: 3D and 4 Any help would be very much appreciated, thank you.
