Elena Chen CH 221-227 November 3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into

Nitrogen cycle Nitrogen gas is a colourless‚ odourless and non-toxic gas which makes up about 78 percent of the atmosphere. Nitrogen is extremely important to living material; in fact plants‚ animals and humans could not live without it. Sprent (1987) argued that nitrogen cycle is the most important process to living organisms after the carbon cycle. But nitrogen exists as dinitrogen (N2) in the atmosphere‚ which living things‚ particularly plants‚ cannot synthesize (citation) The process of nitrogen

Free Data Flow Diagrams Tutorial DFD Tutorial Data Flow Diagrams - Introduction Data flow diagrams can be used to provide a clear representation of any business function. The technique starts with an overall picture of the business and continues by analyzing each of the functional areas of interest. This analysis can be carried out to precisely the level of detail required. The technique exploits a method called top-down expansion to conduct the analysis in a targeted way. [pic] The

Revenue Cycle The revenue cycle is a set of four business activities: Sales order entry‚ shipping‚ billing and cash collections. To each of these activities there are related administrative organisational activities. It is all associated with providing the goods and services of a company to their customers and collecting the payments for these sales. Information about the revenue cycle activities also flows to the other accounting cycles which are: the expenditure cycle‚ the production cycle‚ the

The rise and fall of the economy is basically what is identified as a business cycle. This can be best explained with a simple example. Suppose during

Topic 9 - The Carbon Cycle Aspects of the carbon cycle are similar to the hydrologic cycle because both are good examples of “Interactions between the systems". Textbook – topic not covered in text. http://www.windows2universe.org/earth/ The Carbon Cycle Neglecting the small amount of carbon (C) added to Earth by meteorite impacts‚ there is a fixed amount of carbon on Earth (~800‚000 billion tonnes). All living things are made of carbon but carbon is also a part of the ocean‚ air‚ and

A cycle is defined as any complete round or series of occurrences that repeats or is repeated in the same order and at the same intervals. The natural existence of cycles is highly important without cycles resources would run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each
