Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon

The industrial separation process that I have decided to do is gold separation. Gold separation can be done in a number of ways but there is not always one way to do it‚ but the combination of a couple of these processes to extract pure gold. Gold is obtained form the lithosphere. It is separated from the ore found in the lithosphere. Gold’s symbol is Au. Its atomic number is 79 and has an atomic mass of 196.96655 amu. Its melting point is 1064.43°C‚ while its boiling point is 2807.0 °C. It is

The functions of the government should be differentiated and assigned to separate organs to limit each section to its own sphere of action. So that these organs independently interact between themselves. This is what is known as the theory of separation of powers. ORIGIN OF S.O.P.- ARISTOTLE Its origin can be traced back to Aristotle

We can broaden the spectrum by saying that Creon represents public policy and Antigone represents individual conscience. According to E.S. Shuckburgh we must examine which is more important “state law or divine conscience”. (Shuckburgh xviii) Antigone is a story about two people who choose to make choices that each are passionate
