NH4NO3 ..............> NH4+ + NO3-
thus
NH4NO3 ionizes to NH4+ and NO3- ions.
H2O is polar solvent.
so
ion-dipole interaction occurs.
option D) ion-dipole interactions are formed. (answer)
21. Which of the following is an exothermic process that occurs when NH4NO3 dissolves in water?...
When ammonium nitrate (NH4NO3) dissolves in water, the solution feels cool. Which statements are true? Select all that apply. The process is endothermic. The attractive forces between solvent and solute particles are weaker than between the particles in the pure substances. The process is exothermic. The attractive forces between solvent and solute particles are stronger than between the particles in the pure substances.
Which of the following statements regarding the solution process is incorrect? Multiple Choice When a solution is formed from an ionic compound, the anions and cations are evenly distributed throughout the solution When a polar covalent compound dissolves in water, dipole-dipole interactions take place between the water molecules and the solute molecules. A nonpolar compound such as hexane, C6H14, forms London dispersion forces with a nonpolar solute, such as 12 during the solution process. O The solution process is always...
