purpose of the empirical formula is to find the ratio of any compounds. There are 3 steps to determine the empirical formula: 1. Convert mass percent to mass. 2. Convert the mass of each element to moles. 3. Find the mole ratio of the elements. To determine molecular formula from the empirical formula, the molar mass must be obtained from experiment. Example: % A | g A | X mol A | X mol AY mol B | AxBy | % B | g B | y mol B | | | * Describing compound formulas: in terms of the

Purpose To separate a mixture of two miscible liquids (liquids that mix in all proportions) with different boiling points. Your mixture will consist of water and 2-propanol (isopropyl or rubbing alcohol). | | Menu Purpose Background Safety Procedure Data Analsysis Implications and Applications Concluding Questions | Background Distillation is a physical process used to separate mixtures that contain at least one liquid. Distillation works because each substance in the mixture has its own

Chapter 6 Metabolism The chemistry of life is organized into metabolic pathways Metabolism = Totality of an organism’s chemical processes. Property emerging from specific molecular interactions within the cell. Concerned with managing cellular resources: material and energy. Metabolism begins by the assimilation of nutrients into the body of an organism. This results in a series of stepwise chemical transformations of the nutrient structure. There are two main pathways involved: Catabolic

Water is also used as a transport medium to carry away waste products. As awareness of the importance of improved standards of water treatment grows, process requirements become increasingly exacting. The food industry contributes to a great extent to pollution, particularly as the pollutants are of organic origin. Organic pollutants normally consist of 1/3 dissolved, 1/3 colloidal and 1/3 suspended substances, while inorganic materials are usually present mainly in solution. Dairy Processing

Today, climate problems are on the summit of the international political agenda. Climate change created by humans around the globe is the largest challenge humanity is currently faced with. EU and many national authorities have therefore decided to focus on a re-adjustment toward more environmentally friendly energy production and consumption. Norwegian authorities have set a target of 30 TWh of new electricity production, heat from renewable sources of energy and through energy efficiency by 2016

BIOLOGICALY IMPACTS OF OIL POLLUTION : MANGROVES Mangroves have traditionally provided plant product, fish and shellfish for coastal communities in the tropics. They also provide services such as coastal stabilization and food chain support for near-chore fisheries. This report provides information on the ecology and human use of mangroves, and on the fate and effects of oil. These topics, together with clean-up methods and rehabilitation, are discussed with reference to case history experience
