When magnesium reacts with oxygen to form magnesium oxide, Mgo, a bright light is observed and the reaction gives off heat.
2 Mg(s) + O2(g) --> 2 Mg(s)
How does the potential energy of Mgo compare to the total potential energy of Mg and O2?
O The relative potential energies of the reactant and products cannot be determined from the information given.
OThe potential energy of Mgo is less than the potential energy of Mg and O2-
OThe potential energy of Mgo is the same as the potential energy of Mg and O2.
OThe potential energy of MgO is greater than the potential energy of Mg and O2.
