Phosphoric acid is produced in the reaction between calcium phosphate and sulfuric acid. How much phosphoric acid would be produced if 55 g of calcium phosphate is reacted with 45 g of sulfuric acid. Predict the other product formed. Determine the limiting reactant, excess reactant, and the amount of excess reactant left. Ca3(PO4)2 + 3 H2SO4 ⇌ 2 H3PO4 + 3 CaSO4

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.
