then recrystallize the solute out of the cooled solvent. The formation of concentrated‚ pure crystals is possible in this recrystallization process if the appropriate cooling rate is applied to the solute and solvent mixture. Consequently‚ a purified‚ solid compound would be produced. Recrystallization involves dissolution of a solid in a solvent at elevated temperatures and the reformation of the crystals as the solution cools‚ allowing for impurities to remain in the solution. Once a solid has been

was employed to obtain the single crystal. The acetonitrile was taken in a beaker and the synthesized material was added to prepare the saturated solution. Then the solution was covered by a perforated sheet and kept separately for slow evaporation without any disturbance at room temperature. The crystal growth condition was optimized and grown crystals were purified by successive recrystallization process. Due to the spontaneous nucleation‚ colorless single crystals were obtained in a period of 15

The Bronze Age‚ spanning from 3000-1050 B.C.E.‚ was a time in Ancient Greece characterised by invention and innovation both artistically and architecturally. The Minoans formed the first Greek civilisation on the island of Crete‚ which is located just south of mainland Greece. The name Minoan stems from a series of Greek myths about the legendary King Minos of Crete who was said to rule a vast sea empire; the Minoans were sea-faring people themselves. Minoan civilisation thrived from approximately

the time we return to the initial temperature‚ nearly all of the original material has formed crystals‚ which can be removed from the solvent by filtration. Now‚ suppose that the original solid contained small amounts of impurities. These would go into solution as well‚ but since the impurities are present only in small amounts‚ they remain soluble when the temperature is lowered again. Thus‚ the crystals‚ which come out of solution‚ are more pure than the original sample. This is the essence of purification

For me‚ the most powerful portion of the film took place when members of the Venezuelan military demanded Chavez’s resignation while surrounding the palace with a barrage of tanks and military figures. When Chavez refused to resign‚ the military threatened to bomb the palace. Members of the government were sat on the floor of the palace‚ awaiting some kind of resolution to the ongoing conflict. This portion of the film put me in the position of watching an intense government situation unfold
