If 37.18g of MgCl2 and 4.81 * 10^22 atoms of Cr are mixed and heated a reaction forming pure magnesium occurs as follow:

3 MgCl2 (aq) + 2 Cr (s) —> 3 Mg (s)+ 2 CrCl3 (aq)
Calculate the energy required or released using both reactants and circle the correct value.

Mg = 24.39 g/mole Cl = 35.45 g/mole Cr = 52.00 g/mole
