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

55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction‚ solubility‚ crystallization and vacuum filtration. The experiment was carried out two times‚ both of which were successful. Background Information: This experiment combined all the knowledge of the previous labs performed throughout the semester. An unknown mixture containing an organic acid

Hierarchy and Separation In the Book of Genesis‚ God was the hierarchy and the humans remained sinners or separated from God. He punished his first creations for eating‚ he then flooded the earth to remove all evil and only his true followers survived. He was shown as a "bad" person throughout Genesis. Every one was to fear our great creator. Although‚ in essence‚ he was the superior being and his creations were the lower race. They were not to fear him‚ but to become closer to him and to see him

The reason I thought it was this mixture because of the physical and chemical appearance. I agree with baking soda road salt and citric acid.The baking soda gives the mixture a powdery texture.The road salt are the little pebbles in the mixture. The citric acid is what make the road salt get smaller. The reason i don’t
