To run a thin layer chromatography experiment with a chemical substance, begin by marking a horizontal line near the bottom of a TLC plate with Place a spot of the substance onto the line. For the mobile phase, add a small amount of at the bottom of a TLC chamber. Place the plate in, then the chamber. Once the mobile phase approaches the top of the plate, remove the plate and mark the line.

can you attach a picture of the lettuce? : )

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
