A. Interactions between the ions of sodium chloride (solute-solute interactions).

B. Interactions involving dipole-dipole attractions (solvent-solvent interactions).

C. Interactions formed during hydration (solute-solvent interactions).

D. Interactions involving ion-ion attractions (solute-solute interactions).

E. Interactions associated with an exothermic process during the dissolution of sodium chloride (solute-solvent interactions).

F. Interactions between the water molecules (solvent-solvent interactions).

G. Interactions formed between the sodium ions and the oxygen atoms of water molecules (solute-solvent interactions).

Explanation:

The solution process takes place in three distinct  steps:  

These steps require energy input to break attractive intermolecular forces; therefore, they are endothermic.  

If the solute-solvent attraction is stronger than the solvent-solvent attraction and  solute-solute attraction, the solution process is favorable, or exothermic (ΔHsoln <  0).  If the solute-solvent interaction is weaker than the solvent-solvent and solute-solute  interactions, then the solution process is endothermic (ΔHsoln > 0).  

In the dissolution of sodium chloride, this process is exothermic.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
