Analysis of Oxygen Bearing Compunds

Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary), 2° (secondary), 3° (tertiary) alcohols. Tests such as the dichromate test, Tollen’s test, Lucas test, DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment, the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result...

Oxygen and Lead Acetate

Date: 9th February, 2011 Title: Analysis of the Elements present in Organic Compounds Aims: To test the presence of Carbon, Hydrogen, Oxygen, Nitrogen and Sulfur in Organic Compounds Introduction: Organic Compounds can be considered as any compound containing carbon atoms covalently bonded with other atoms, usually hydrogen. Other atoms may include oxygen, nitrogen, sulfur…etc. They can be found in nature, since “organic” means present in, or derived from, plants and animals. Materials/...

Oxygen and Forests Introduction Trees

IMPORTANCE OF FORESTS Introduction Trees are mankind lifeline. If they are destroyed, there is no way that human beings can survive. From the oxygen that we breathe in, the food that we eat, to the clothes we wear, we owe it all to the trees. Not only this, trees act as purifiers of air and receptacles of our waste products. Trees have great economic value too. We get fuel, fodder, timber, medicines and numerous other valuable products from the trees. It is, therefore, not surprising that trees...

Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the periodic...

Metallurgy: Oxygen and Ore

SiO2 → FeSiO3. (b) Reduction of oxide to the metal Reduction of the metal oxide usually involves heating it with some other substance acting as a reducing agent (C or CO or even another metal). The reducing agent (e.g., carbon) combines with the oxygen of the metal oxide. MxOy + yC → xM + y CO. Hydrometallurgy Leaching: (agents; NaOH, Hcl, H2So4) Usually done for low grade ores. Leaching is often used if the ore is soluble in some suitable solvent. The following examples illustrate the procedure:...

Modified Winkler Method for Dissolved Oxygen Determination

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater is...

Biology - Blood Technologies for Oxygen and Carbon Dioxide Measurements

Year 12 Biology Research Tasks Maintaining a Balance Task 3 Blood Technologies for Oxygen and Carbon Dioxide Measurements It is essential in our bodies that oxygen and carbon dioxide levels are in appropriate and healthy amounts within the bloodstream as the excess or lack of the gases becomes detrimental to the being. Fortunately, current medical technologies allow us to monitor and measure the levels of oxygen and carbon dioxide within the bloodstream with a simple test. The pulse oximeter and...

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals Brianne Simonsen Lab Section 8 4 Oct. 2005 Abstract In this experiment the oxygen consumption of a mouse in environments of varying temperatures was studied. The hypothesis behind this experiment was that more oxygen would be consumed at a lower temperature to maintain body heat. To measure the rate of oxygen consumption a mouse was given a specific amount of oxygen. The amount consumed in a specific time was measured...
