In a chromatography experiment, samples can be separated based on their polarity. If you have a polar solvent and nonpolar chromatography sheet, what conclusion can be drawn from analyzing the results? A. The sample that travels farthest up the sheet is most like the solvent, therefore it must be polar. B. The sample that travels farthest up the sheet is most like the solvent, therefore it must be nonpolar. C. The sample that doesn't travel at all and stays near the origin is most like the sheet, therefore it must be polar.  D. The sample that doesn't travel at all and stays near the origin is most like the solvent, therefore it must be polar.

Explain why some “Green Energies” are not so green by giving an example.short answer please

When measuring the caffeine content in coffee, the molecules in the sample will absorb light. The absorbed light data provides information that can then be used in determining the concentration of caffeine.      Both statements are correct.     1st statement is True. 2nd statement is False.     1st statement is False. 2nd statement is True.     Both statements are False.

Please answer all items will give you thumbs up and good rating. Each item consists of two statements (I and II). Identify if each statement is either true or false, then select the appropriate answer from the choices.
