When magnesium is heated in air, most of the magnesium reacts with the oxygen of the air, but a significant amount does react with the nitrogen of the air. If water had not been added to your initial product, a mixture of magnesium oxide and magnesium nitride would have resulted. What error in the percentage magnesium determined for your product would have resulted if a portion of the product were magnesium nitride instead of magnesium oxide? Explain.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
