Here's a problem for the student to solve:Design a remediation plan for a hypothetical contaminated site that has been contaminated with heavy metals. Discuss the various treatment options available for the site, the advantages and disadvantages of each option, and the costs associated with each option. Finally, recommend a remediation strategy that you think would be the most effective and economically feasible for the site.

Calculate the lattice energy of magnesium oxide (MgO) given that the magnesium ion has a charge of +2 and the oxide ion has a charge of -2. The lattice energy can be calculated using the Born-Haber cycle and the following data:- The enthalpy of sublimation of magnesium (Mg) is 147 kJ/mol- The first ionization energy of magnesium is 738 kJ/mol- The enthalpy of formation of MgO is -601 kJ/mol- The electron affinity of oxygen is -141 kJ/mol- The enthalpy of dissociation of oxygen molecules is 498 kJ/mol.
