Answer:
use chemical equation to that answer
Since density is mass/volume, the density is 5g/ml.
Answer: B, E and F.
Explanation:
Just took a test on it and those were the correct answers.
OH⁻, BeCl₂ and SiF₄ are Lewis acids whereas, Mg²⁺ is a Lewis base.
<h3>What is a Lewis acid-base reaction?</h3>
- According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
- Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
- Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
- Here OH⁻, BeCl₂ and SiF₄ are electron deficient whereas, Mg²⁺ donates the electrons to other species present in the reaction.
- From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.
