Na tlc analysis, if the solvent was observed to travel 10.0 cm and the spot was observed to travel 4.70 cm, what is the rf for that spot?

TLC stands for thin layer chromatography. Here we use a stationary phase like silica and a mobile phase, the solvent. when an analyte is run over stationary phase, the solvent is chose in such a way that it is will run faster than analyte. Rf stands fir retention factor. Rf is the ratio of distance travelled by analyte to distance traveled by solvent. It can never be greater than one. In the given question: Rf= 4.70cm/ 10 cm= 0.470 Thus it is a unit less term.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
