The distillation technique most suited for separating glycerol from spent-lye in the soap industry is: (1) Fractional distillation (2) Steam distillation (3) Distillation under reduced pressure (4) Simple distillation
Explain each process please.
Write the reaction with water that is the ionization of propionic acid to propionate, draw this out in two ways. First with expanded structures, of course, all atoms and all bonds.
What mass (in grams) of calcium carbonate is needed to react completely with 69mL of 0.12 M HCL according to the following equation. 2HCl(aq)+CaCO3(aq)-->CaCl2(aq)+H2O(l)+CO2(g)
If the pressure of the ocean breaks the submarine forming a bubble with a pressure of 250 atm pushing on it, how big will that bubble be?

Derrick used propane(C3H8) to barbeque during the summer. Please write down the whole combustion reaction and balance the eqation. There are 3.6x10^25 CO2 molecules created, how many grams of oxygen were needed for the reaction
Use values of ksp and kf for copper (II) hydroxide and its complex to predict if a precipitate should form in a 0.1 M Cu2+ solution that is 3M in OH-
The precipitate, after having been filtered and air-dried, has a mass of .284 g. The limiting reactant in the salt mixture was later determined to be CaCl2x2H2O.
A 45.3 g sample of Al at 95.5 oC is added to 182.7 g of water that is initially at 20.5 oC. The specific heat of Al and water are 0.90 J/(goC) and 4.184 J/(goC), respectively. Calculate the equilibrium temperature.
A sample containing 2.20 moles of neon gas has a volume of 8.00 L. Assume that the pressure and the temperature remain constant. What is the new volume of gas in liters when a sample of 70.0 g neon is added to the neon gas already in the container..
