Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece
