Geothermal Energy
... of power with relative efficiency, it is very hard to dispose of the waste. While wind and solar power have no waste products, they require enormous amounts of land to produce any large amounts of energy. I believe that geothermal energy may be an alternative source of energy ...
Nitric Acid
... Ammonia and air are passed over a heated platinum catalyst at 900 degrees centigrade. An exothermic reaction takes place producing nitrogen monoxide and steam. The mixture of gases is cooled and nitrogen monoxide reacts with further oxygen in the air to produce nitrogen dioxide: The nitrogen dioxide ...
PEF:THE FUEL OF FUTURE
... Fuels Institute, these fuels are produced from waste products, are pelleted, are environmentally clean and have been designed to be traded as a commodity. This paper discusses PEF as a modern source of energy. INTRODUCTION: Plastics are derived from petroleum and natural gas and ...
Lab report on gas chromatograph and the optical activity of carvones.
... of Carvones Kyle Peterson Chem. 243a Matt Judd, Sec. 25 Date Performed: 10/29/03 Abstract: The objective of this experiment is to use Gas Chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and ... tested in a GC machine and ...
A Brief History of the Periodic Table
... units could be written per turn, so that closely related elements lined up in vertical columns. With his periodic table, De Chancourtois stated, "The properties of the elements are the properties of numbers." He was also able to predict the stoichiometry of certain metallic oxides ...
Information on the biopolymer poly-hydroxybutanoate (PHB)
... of PHB is that it is biodegradable. Therefore, this allows better waste management, and of being made from renewable crops rather than fossil fuels, which are gradually becoming depleted. PHB has low environmental impacts and does not emit toxic gases that are involved in the production of ...
Monitoring Rates -HCl and Mg
... and minimal activation energy) and react with, as they are being used up, with perhaps Mg as the limiting reagent. Variables: INDEPENDENT - is changed. For this particular investigation, we were only aiming to observe the effect of time on the rate of reaction between the strip of Mg and ...
Constructing A Killer PC
... power supply with the appropriate number of connectors. Also make sure the case has a removable motherboard pan. This will make life much easier when it's time to make repairs and upgrades. Now that we know what we want it's time ...
Calometer Lab
... of the experiment. Because the calorimeter was not properly insulated, the heat was able to escape and the percent efficiency was lower. There were many flaws in the experimental design as well. There were not enough oxygen and carbon dioxide holes to fuel the combustion of ...
The Process of decomposition of mixtures into compounds and elements: Grey Water and Crude Oil
... of energy and takes a long time for the liquids to distil. But when using this method on a mixture such as crude oil where most of the separated components can be used to make by- products and to even increase the value of products, fractional distillation is a favourable and ...
