Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series. Introduction Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products. The molar heat of combustion of a substance is the quantity of heat liberated when one mole of that substance is burnt completely in air. In the case of a hydrocarbon‚ the products

Air Powered Car A compressed air car is a car that uses a motor powered by compressed air. The car can be powered solely by air‚ or combined (as in a hybrid electric vehicle) with gasoline‚ diesel‚ ethanol‚ or an electric plant with regenerative braking. History Compressed air has been used since the 19th century to power mine locomotives and trams in cities such as Paris (via a central‚ city-level‚ compressed air energy distribution system)‚ and was previously the basis of naval torpedo propulsion
