Discussion/Analysis1.If gas bubbles form then fermentation occurred. Glucose. Carbon dioxide. The enzyme didnt recognize the structure of glactose, because of the orientation of the H and OH on the carbon 4 is different than glucose. The enzyme only identifies very specific substances. 2.In order to determine how fast a reaction is occurring there must be …

Transition Elements

Transition Elements, series of chemical elements that share similar electron orbital structures and hence similar chemical properties. The transition elements are commonly defined as the 30 elements with atomic numbers 21 to 30, 39 to 48, and 71 to 80. The transition elements exhibit multiple valences or oxidation states typically ranging from +1 to +8 …

O3 the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is …

Chemistry Of Natural Water

The purpose of this experiment is to explore thehardness of the water on campus. Hard water hasbeen a problem for hundreds of years. One of theearliest references to the hardness or softness ofwater is in Hippocrates discourse on water qualityin Fifth century B.C. Hard water causes manyproblems in both in the household and in theindustrial …

DistillationAndrea PausmaOctober 1, 2001I.IntroductionThe process of distillation has been used by humans for years to create alcoholic beverages. Distillation is the process of boiling a pair of liquids with different boiling points and then condensing the vapors above the boiling liquid in an attempt to separate them. One might suspect that the mixed two liquids …

Why Xeon Doesn’t React

Xenon is a rare, colorless, odorless, tasteless, chemically unreactive gas. It is one of the inert gas elements found in group 0 of the periodic table. Xenon was long considered incapable of chemical reaction, but in 1962 Neil Bartlett, a Canadian chemist, reported synthesis of xenon hexafluoroplatinate, XePtF6, a true compound. Before 1962, people thought …

Chloroflourocarbons

ChloroflourocarbonsChloroflourocarbons were discovered in the 1920’s by Thomas Midgley, anorganic chemist at General Motors Corporation. He was looking for inert, non-toxic, non-flammable compounds with low boiling points that could be used asrefrigerants. He found what he was looking for in the form of two compounds:dichlorodifluoromethane (CFC-12) and trichloromonoflouromethane (CFC-11). Inboth compounds, different amounts of chlorine …

Nitrogen

Nitrogen was isolated by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist Antoine Laurent Lavoisier about 1776.Properties Nitrogen is a colorless, odorless, tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can in turn be compressed into a colorless, crystalline solid. Nitrogen exists …
