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

Aim: The aim of this experiment is to determine which fuel‚ out of Pentane‚ Propane-1-ol and Propane-2-ol would be the most appropriate to take on a camping trip to a national park where wood cannot be used to burn. Factors that need to be considered are: • Heat of combustion (flash point) • Heat of vaporisation (boiling point) • How long the fuel will last • Does the fuel heat up the water relatively quickly • Does the fuel combust completely Hypothesis: If the tests are all successful‚ Pentane

handout & pen ruler watch glass 400 mL beaker CO2 indicator solution (limewater) 50 mL beaker (for indicator) Procedure My lab partner and I performed a series of experiments to investigate the chemistry of the burning of a candle. The teacher provided the following chemical equation to describe the burning‚ or combustion‚ in the candle: Hydrocarbon fuel + O2 CO2 + H2O The candle we used was a small‚ white emergency candle about 3.5 cm tall. The candle had already been used by someone

Capacity for a Calorimeter and of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The enthalpy of reaction for an acid-base reaction

The Enthalpy of Formation of Magnesium Carbonate By: Jessica Miller T.A: Thomas Lab Partner: Rebekah Melanson Thursday Lab Room 106 Chemistry 1001-A Due Date: Thursday February 3rd 2011 Abstract The purpose of this experiment was to determine the enthalpy of formation of magnesium carbonate in a lab setting. This was done using a calorimeter‚ which was calibrated by adding a known amount of both hot and cold water. Following the calibration of the calorimeter‚ HCl was placed into the empty calorimeter

In this lab‚ I calculated the heat of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the

Internal Combustion Engines An internal-combustion engine is a heat engine that burns fuel and air inside a combustion chamber located within the engine proper. Simply stated‚ a heat engine is an engine that converts heat energy to mechanical energy. The internal- combustion engine should be distinguished from the external- combustion engine‚ for example‚ the steam engine and the Stirling engine‚ which burns fuel outside the prime mover‚ that is‚ the device that actually produces mechanical
