Explanation:
the physical and chemical properties of an element are periodic functions of their atomic number.

The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.
Reactants are the starting substances and products are the ending substances in a chemical reaction.
The atoms in reactants are arranged one way and are rearranged in a different way to form the products (in other words, reactants are chemically different from products).
The properties of reactants differ from the properties of products. Good answer for E.DG.
(NH₄)₃PO₄ is a strong electrolyte which fully dissociates into its ions. The balanced equation for the dissociation is
(NH₄)₃PO₄ → 3NH₄⁺ + PO₄³⁻
The stoichiometric ratio between (NH₄)₃PO₄ and NH₄⁺ is 1 : 3
Hence, moles of (NH₄)₃PO₄ / moles of NH₄⁺ = 1 / 3
moles of (NH₄)₃PO₄ = 3 mol
Hence, moles of NH₄⁺ = moles of (NH₄)₃PO₄ x 3
= 3 mol x 3
= 9 mol
Hence, 3 moles of (NH₄)₃PO₄ give 9 moles of NH₄⁺.
