1.The prediction of melting point rank can be useful when discussing the different applications of substances. Rank the following 4 substances from highest to lowest melting point. Include your reasoning for your rank based on intermolecular forces of attraction and support your reasoning with Lewis structures. Ammonia, NH₃, Magnesium oxide, MgO, Sodium oxide, Na₂O, Carbon dioxide, CO₂
