Lab Report 3: Combustion of Magnesium and Specific Heat of a Metal C4C Jeffrey Silvin Fall 2017 Major Kittle Chem 100 T1 Introduction The purpose of this lab was to determine an experimental value for the heat of formation of MgO with Hess’s Law and then use the result to find percent error. To do so‚ approximately 50 mL of 1.0 M HCl was added to a calorimeter. Initial temperature was measured and then 0.25 g of Mg was added. After the reaction is completed the maximum temperature was recorded.

From the experimental data and through its analysis‚ the enthalpy of combustion for the five alcohols were determined; methanol‚ ethanol‚ propanol‚ butanol‚ and pentanol. As the line of best fit in the graph suggests‚ the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph‚ the enthalpy of combustion increases from 140kJ/mol for methanol‚ which has the smallest molecular mass‚ to 530kJ/mol
