Donald Trump‚ our elected president promised to make America great again. He promised to do many things‚ some of them seem possible to fulfill‚ others are unlikely to happen. Since The USA has a strict principle of separation of powers‚ his power must be shared with the Congress and the judiciary.

Knowing that the repeal of Obamacare

Chem 1211L Mrs. Amy Cook February‚ 9 2011 Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because
