Answer:
633.5
Explanation:
The total presser is 650.00 mmHg, and it is collected over water, which at 19c is 16.5 mmHg. Therefore, to get the total pressure of H2 you would subtract the partial pressure of water from the total pressure.
650-16.5=633.5
Answer is: ammonia has a higher boiling point because it has stronger intermolecular forces.
Intermolecular forces<span> are the forces between </span><span>molecules. The stronger are intermolecular forces, the higher is boiling point of compound, because more energy is needed to break interaction between molecules.
</span>There are several types of intermolecular forces: hydrogen bonding, i<span>on-induced dipole forces, ion-dipole forces andvan der Waals forces.</span>
