Question 1 The dissociation energy is the energyr to separate what? D The atoms held together by a covalent bond {3 The molecules held together by a van der Waals bond ('3 The ions held together by an ionic bond For the water molecule, what kind of bonding is happening between the two hydrogen atoms. C: Ionic bonding. D van der Waals bonding. C: There is no bonding between the hydrogen atoms. Each hvdrogen atom i5 separately bonded to the same oxygen atom. Q Covalent bonding. Question 4 Water molecules are weakly attracted to each other. This is why water beads up on a window. What is the reason for these weak molecular bonds? O The bonding between nearby water molecules is ionic in nature. O The bonding between nearby water molecules is covalent in nature. O Water molecules are actually permanent electric dipoles and van der Waals bonding happens. O The net electric charge of water molecules is responsible for the weak attraction between water molecules.Question 1 A parameter labeled n is called the repulsion parameter. it appears in the potential energy term describing the repulsion between nearest neighbor ions. How is n described by the book to be determined for a particular pair of ions? Cr It's determined experimentally. C: It's determined by Coulomb's Law. (3: It's determined by Pauli Exclusion Principle. Question 3 What are the units of n, the repulsion parameter? O no units; pure number O energy units O distance units O charge units
