Karl Marx’s Philosophies on Communist Manifesto‚ Dialectic Materialism and Labor Theory of Value Introduction: "The philosophers have only interpreted the world‚ in various ways: the point‚ however‚ is to change it." ~ Karl Marx One hundred years after his death. Marx is an enormous presence among us. On purely quantitative criteria‚ judged by the number of his self-avowed followers‚ he exerts a greater influence than any of the religious founders or any other political figures

Experiment #1: Separation of Acid‚ Base‚ and Neutral Compounds from a Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are

of two 5-membered rings situated directly above and below the metal center. It looks like an iron sandwich. The reaction of molybdenum hexacarbonyl and mesitylene is unstable with respect to air. Because inorganic chemists desire to work with compound that have some component that is air sensitive‚ they have devised a couple of ways to manipulate air-sensitive materials. We will focus our efforts on the use of a Schlenk line in this laboratory. A Schlenk line is a piece of equipment that is designed

Abstract An experiment was conducted to determine the effect of the allelopathic compounds of Encelia Farinosa (brittle bush) on desert native annuals and non-native seed germination. The experiment was set up by putting native wild flower seeds in six Petri dishes and lettuce seeds in six different dishes. To three of each dish containing the different seeds‚ water was added as a control. To the three other dishes‚ a prepared brittle bush tea (filtered ground brittle bush leaves and water) was
