3) correct
4)incorrect
Explanation:
1) A Lewis acid is a substance that accepts a nonbonding pair of electrons.
A Bronsted-Lowry acid is a substance that donates a proton H⁺
Since the donation of a proton involves the acceptance of a pair of electrons, every Bronsted-Lowry acid is also a Lewis acid.
2)A Lewis acid not necessarily needs to have a proton to be donated.
3) Conjugated acids of weak bases are strong acids and conjugated acids of strong bases are weak acids.
4)K⁺ comes from a strong base, therefore is does not have an acidic behaviour.
Answer:
La química se relaciona con diferentes ciencias, por eso se dice que es multidisciplinaria, como la física, las matemáticas, la bioquímica, la astronomía, la biología, entre otras. Gracias a esta interrelación es posible explicar y comprender los complejos fenómenos de la naturaleza.
