Lab a report1. thin layer chromatographya. (true/false) for a given sample, a single tlc spot is an absolute indication of sample purity. explain. b. if a single solvent, such as ethanol (instead of a solvent mixture such as acetic acid/ethyl acetate) were used toelute the samples on the tlc plate, would you expect the rf values to be greater or less than those you recorded

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
