Title How Hot Is That Flame? Sophie Scheidlinger, author Lindsay Collishaw, lab partner Experiment 6 November 2, 2007 Purpose Using calorimetry to find the experimentally determined heats of related magnesium reactions in order to find the heat of reaction for burning magnesium metal. Methods The calorimetry was conducted according the procedure outlined on pages 63-65 in the General Chemistry 1A Laboratory Manual for Fall of 2007. Be sure to close the lid as tightly as possible and as quickly as possible to maintain accuracy in recording data. Make sure to swirl the contents of the thermos in order to maintain the accuracy of the thermometer readings. If any of the diluted HCl solution spills anywhere, immediately notify an adult and wash the affected area with distilled water. Graduated cylinders can be read to the nearest mL. When using graduated cylinders, make sure to read the bottom of the meniscus for an accurate measurement to the nearest mL. When using digital balance and weighing boat to weigh magnesium, record weight to nearest 0.001 g. It is impossible to get all of the MgO into the calorimeter, so reweigh the calorimeter after the experiment in order to determine how
