Combustion of Alcohols Purpose: The purpose of this investigation is to use calorimetry to determine the molar enthalpy change in the combustion of each of a series of alcohols. Question: How do the enthalpies of combustion change as the alcohol molecules become larger? Prediction: I predict the bigger the molecule the more the energy will be released. Materials: On lab sheet Procedure: On lab sheet Observation: On other page Analysis: b) i) Ethanol – q=(100g)(4.18J/g/C)(25.5C) q=10659J

Self Heating Food and Drink Cans Heater meals – originally developed for military use – are ready-made self-heating meal packs. They can be heated in many ways – by pressing a button on the packaging‚ unwrapping and shaking the pack‚ or pouring the contents of one bag into another and waiting for a few minutes – all of which use exothermic chemical reactions. These meals can be used to motivate students to study such reactions relatively safely and without the use of a burner. Plus there is the
