2024年1月9日 · Hess’s Law and the Enthalpy of Combustion of Magnesium Introduction Magnesium burns in air in a highly exothermic combustion reaction according to the balanced equation: Mg (s) + ½ O 2(g) MgO (s) Using calorimetry to determine the enthalpy of this reaction is impractical due to the excess of heat produced. It would melt the calorimeter.

Hess Law Lab Report - 702 Words - bartleby
As explained before, Hess’s Law states that the enthalpy change of reaction three (ΔH3) should be equal to the sum of the enthalpy changes of the first two reactions ( ΔH1 + ΔH2 ). As seen at the equations, the solid NaOH dissociates into its ions, after that it is neutralized by HCl. DATA …show more content… Only random errors were made.
