Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

Revealing Trans Fats Informative Abstract Trans fats are fats resulting from the process a product undergoes in adding hydrogen to vegetable oil by turning liquid oils into solid fats and based on evidence supported‚ if consumed it would increase the risk of coronary heart disease and promote bad cholesterol at an high rate especially among Americans; it is therefore one of the leading causes of death in the United States. As a precautionary measure to counter this mass effect of trans fat the

Combustion of Acetylene (ethyne) Rx: Back Why I don’t do acetlyene explosions in our lab.... Combustion of alkanes A quick review.... • Combustion reactions of alkanes consist only of C and H (hydrocarbon) • require O2(g) as a reactant • produce CO2(g) and H2O(g) and a large amount of energy!! Oxygen can be the limiting reagent which can lead to Incomplete combustion. For complete combustion of a hydrocarbon‚ oxygen must be in excess. If there isn’t sufficient oxygen‚ incomplete combustion occurs
