Provide the conjugate acid-base pairs in the following balanced chemical reaction:

CH₃CH₂NH₂(aq) + H₂O(l) ⇋ CH₃CH₂NH₃⁺(aq) + OH⁻(aq)

True or False: Based on the following reaction, the reactant that acts as the Brønsted–Lowry acid is HNO₃, while the Brønsted-Lowry base is H₂O.

HNO₃(aq) + H₂O(l) → NO₃⁻(aq) + H₃O⁺(aq)
