How do ionic compounds form? How do electrons change the shape of a molecule? These are just a couple of the questions that this paper will answer. How do ionic compounds form? Ionic compounds are formed by positive and negative ions. An ionic bond means that there are valence electrons being shared between the two molecules. This can cause the molecule to become negative or positively charged. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the

Abstract The purpose of this paper is to gain an understanding about what alcohol is‚ how alcohol is produced‚ the metabolic processes involved with the breakdown of alcohol in the body and the enzymes that catalyze these reactions and how these biochemical reactions affect the liver and brain and the effects of alcohol on the human body. Introduction A good deal of the population consume alcohol‚ some more than others. The effects of alcohol consumption on the human body affects mainly the

Hydrogen VS biodiesel: * Biodiesel solidifies in cold temperatures and it is harder

We then tested for the PH value and it was neutral. The flame test was negative. There was no pigment in the flame. For our second unknown‚ the substance color was powdery-white‚ glittery‚ and clumpy. The odor was like rubber. When we tested the solubility in water in water it resulted soluble and in ethanol as well. The electrical conductivity

oil prices a few years ago‚ there has been renewed interest in expanding the United States production of biofuel and biodiesel. Biofuel or ethanol is a replacement‚ or additive‚ for conventional gasoline; where biodiesel is a replacement to conventional diesel. According to the US Department of Agriculture (USDA)‚ most gas stations in the US now have ethanol as an additive to the gasoline we purchase on a regular basis (www.usda.gov). History of Biofuel Biofuel and biodiesel are not a new development

World’s Fuel Crisis Von Philip Bethge Dan Robertson is working on algae that can produce biofuel. Genetically modified blue and green algae could be the answer to the world’s fuel problems. Bioengineers have already developed algae that produce ethanol‚ oil and even diesel -- and the only things the organisms need are sunlight‚ CO2 and seawater.

consecutive years. Coal was once again the fastest growing fossil fuel‚ with predictable consequences for carbon emissions [BP Statistical Review of World Energy‚ 2012]. Ethanol fuel is the most common biofuel worldwide‚ particularly in Brazil and USA which is produced from several biomass feedstocks and different technologies [].The ethanol production methods are respectively‚ enzyme digestion (to release sugars from stored starches)‚ fermentation of the sugars‚ distillation and drying. The distillation

and the battery life for a charge is only 37 miles. There would be no value for us to use electric cars. (Courture‚2011). Ethanol is a grain- based alcohol that has been used to supplement petroleum since the 1970’s. A disadvantage is it costs about three times more to produce then gasoline. It also will take about 1.5 times the amount of ethanol as it would with gas to operate a vehicle. Additionally‚ current fertilizer is petroleum-based‚ thus undercutting the true value of using
