Answer:
NH3 and H2O
Step-by-step explanation:
In chemistry, the overarching principle of like dissolve like decides the solubility of one substance in another. This principle is ultimately hinged on the idea of intermolecular forces existing between substances. Polar substances dissolve polar substances while nonpolar substances dissolve nonpolar substances in accordance with this principle.
Both NH3 and H2O are polar substances that contain the hydrogen bond. Intermolecular hydrogen bonding interaction accounts for the solubility of NH3 in H20.
