A student was given an unknown compound dissolved in acetone. The student decided to identify the compound by TLC. The student decides to use a 1:1 hexanes/acetone solvent system. Once the TLC plate was finished running, the student pulls out the TLC to look at it under UV. The student's partner remarks that none of the spots showed up. What would be best for the two students to try next? O A. Redo the TLC plate; it was the students technique that caused the problem. E. Concentrate the sample solution used. C. Both D and E. O D. Spot the unknown compound and see if it shows up under UV without running the plate. B. Use potassium permanganate stain on the plate to see if it shows up.

When a meteorologist reports precipitation in the weather forecast, this is usually associated with a low-pressure system. Go through the following activity to explain why precipitation would be associated with a low atmospheric pressure. Air that is saturated or contains water vapor will have more water and [ Select ] v dry air in the overall mixture compared to dry air. This causes the overall density of the air to [ Select ] V. The air will be [ Select ] dense than dry air and the atmospheric pressure will be [Select] than dry air.
