Among the most harmful and dangerous non-metal compunds are nitrogen oxides‚ sulphur dioxide‚ carbon dioxide‚ carbon monoxide‚ and hydrogen sulphide. These can cause devastating effects to human beings‚ plants‚ animals and the environment. Matals are generaly less harmful‚ although lead is extremely toxic. Hydrogen sulphide is a highly toxic gas. It has a very bad smell‚ often identified in rotten eggs and stink bombs. Hydrogen sulphide interferes with cellular respiration. If inhaled‚ Hydrogen

JAMES. Development of the Metal Foam Electrical Resistance Heater. (Under the Direction of Dr. Albert Shih.) This thesis presents a novel concept using a radial heating element made from porous Fe-Cr-Al metal foam in an air heater. Electrical resistance heating has been used extensively to convert the electrical energy into thermal energy. An analytic heat transfer model is first developed to estimate dimensions of the heating element. Four prototype Fe-Cr-Al metal foam electrical heaters with

The key issue in the case is that the incentive compensation system does not motivate district managers to make decisions which are consistent with the strategy of Quality Metal Service Center (QMSC) because it is tied to the district’s target ROA. Acquiring the new processing equipment reduces the incentive bonus of the Columbus District Manager‚ Mr. Ken Richards‚ from 11.1% to 4.28% of his base salary. This happens because the asset base increases with the new equipment and will exceed the target

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For calcium‚ the gas
