Matti is given two bottles of copper (II) sulfate solutions in her senior high chemistry lab. She is told that one bottle contains a saturated solution and the other one contains an unsaturated solution. The solutions are the exact same color and have no particles in the bottles.

7) The most important reaction that allows our cars to do work is octane (CSH18) combustion 2 C8HI8 + 25 02 à 16 C02 + 18 H20 a) Theoretically speaking, if we fully combust 3.0 kg of octane, and keep the products at STR, what volume of gas do we expect to be produced? b) If the % yield for this combustion reaction is 90%, what is the actual volume? 8) Name two characteristics that describe real gases and not ideal gasses. 9) a) A climber takes a mole of ideal qgas to the top of Mount Everest, where the pressure is 304 torr and the temperature is subzero at -17° C. What is the volume of the gas? b) The gas taken to Mount Everest is oxugen gas. What is the root mean square velocity of gas molecules in that sample of gas? 10.) a) An 8.00L tank at 7.3° C is filled with 24 g of dinitrogen monoxide (N2O) and 8.2 g of sulfur hexafluoride gas (SF6). What is the mole fraction of sulfur hexafluoride? b) What is the ratio between the rates of effusion of sulfur hexafluoride and dinitrogen…

Determine the structures of the missing organic molecules in the following reaction: Y II OH X + H₂O H+ H* OH Note: Molecules that share the same letter have the exact same structure. In the drawing area below, draw the skeletal ("line") structures of the missing organic molecules X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure. C X :0 Ś m c+
