A chemistry student needs to determine the enthalpy of oxidation of magnesium. For this, they need to conduct an experiment in which they react 1 gram of magnesium metal with excess hydrochloric acid of 2 moles concentration. They need to measure the temperature change that occurs during the reaction, which they will use to calculate t

To determine the enthalpy of oxidation of magnesium, we first need the temperature change  T  that occurs during the reaction. Since this information is not provided, I will guide you through the steps to calculate the enthalpy of oxidation once you have the temperature change.1. Calculate the moles of magnesium used in the reaction:Magnesium has a molar mass of 24.31 g/mol. moles of Mg = mass of Mg / molar mass of Mgmoles of Mg = 1 g / 24.31 g/mol = 0.0411 mol2. Write the balanced chemical equation for the reaction between magnesium and hydrochloric acid:Mg  s  + 2 HCl  aq   MgCl2  aq  + H2  g 3. Measure the temperature change  T  during the reaction using a thermometer.4. Calculate the heat  q  released or absorbed during the reaction using the formula:q = mcTwhere m is the mass of the solution  assume it is approximately equal to the mass of water used , c is the specific heat capacity of the solution  4.18 J/gC for water , and T is the temperature change.5. Calculate the enthalpy change  H  per mole of magnesium:H = q / moles of MgOnce you have the temperature change, you can follow these steps to calculate the enthalpy of oxidation of magnesium according to the student's experiment.
