(Q53) For what reason is the solubility of gaseous ammonia (NH3) significantly higher than that of hydrogen gas (H2) at the same temperature and pressure? O Because they are both polar molecules, the solute-solvent interactions are higher between ammonia and water than they are between water and hydrogen gas O Ammonia reacts with water primarily through dispersion forces O Ammonia has a relatively high boiling point O Ammonia has a larger molar mass than does hydrogen gas O Ammonia is an inorganic (carbon-free) molecule
