Investigation of Combustion of Alcohols Aim The aim of this experiment is to investigate the combustion of various alcohols. The alcohols will be burnt to heat up a test tube of water‚ I aim is to find out how much energy is produced when burning the following alcohols: Methanol‚ Ethanol‚ Propanol‚ Butanol‚ and Pentanol. Any form of burning is an exothermic reaction (heat is given out)‚ this means that the reactants energy is higher than that of the product. Alcohols react with

In this lab‚ we will measure the heat of combustion‚ or calorimetry‚ of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab‚ we must first determine the mass of the tea candle. Then‚ we will determine our room temperature‚ measure about 100 mL of chilled water‚ and then pour the water into the given empty

So in wood combustion we observe solid wood disappear and be converted to gas products‚ leaving only some ashes. These are formed by minor components of wood that cannot burn and remain solid. 1. Explain what happens to the mass of a tree when it catches fire and burns until only ashes remain. You must include a chemical equation; discuss the chemical reactions taking place‚ and the law of conservation of mass in your answer. The wood from the tree has undergone a chemical change. When you burn

the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel‚ which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen
