The suggested procedure for spotting a sample on a thin‑layer chromatography (tlc) plate involves transferring a droplet of concentrated solution from a capillary onto the plate, allowing it to dry, then repeating the process over the existing spot. why is it advised to spot multiple times? to achieve a high concentration of sample in a large spot to facilitate visualization by having a higher compound concentration to fill the capillary almost instantly by capillary action to prevent the solvent in the developing chamber from evaporating

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
