Stephen Wilson (SID# 18974524) Lab Partner: Nelson Wong GSI: Trevor Ewers Experiment #6 November 5, 2007 Chem 1A Section 110 LAB How Hot Is That Flame? Purpose: The purpose of this lab was to calculate how much energy is released by burning magnesium metal. Methods: The energy released by burning magnesium was calculated using a calorimeter to trap the heat released so it could be used in further calculations. First the heat capacity of the calorimeter had to be found out by using a reaction with a known ∆H: adding cold water to warm water. The first thing done was to record the mass of the calorimeter, but not for any calculations other than to figure out the mass of what was inside. The mass of the calorimeter was not needed because it did not change at all, so it was combined into the K cal . Room temperature was then put into the calorimeter and an ice bath was additionally prepared, then, after the two temperatures had stabilized, some of the ice water was poured into the calorimeter. Calorimeter readings were
