Use your results from #4 and data Table 8.1 to calculate the value of DHf for Mg†² (aq) Note: You must write out the formation equations of all products and reactants and sum to find the change in enthalpy for the formation of the cation (like example 8.3). Failure to do so will result in zero credit.
