Which risk increases when magnesium oxide (MgO) forms?

A)Exothermic reaction heat propagation
B)Endothermic reaction rate decrease
C)Metallic bond electron delocalization
D)Convalent bond dipole moment increase

💡 Explanation

Exothermic reactions occur because *ionic bond* formation in magnesium oxide (MgO) releases considerable heat; therefore, a runaway reaction becomes more likely, rather than endothermic rate slowing or increased electron delocalization from metallic bonding/dipole moments.
