Answer:
Ester Linkages
Explanation:

(1) CaCO3 is the correct answer.
The type of bond formed between Ca2+ and CO3 2- is ionic, and the type of bond formed between C and O is covalent.

The lithium ion[Li⁺]=1.642 M
<h3>Further explanation</h3>
Ionic compounds will dissociate into ions when dissolved in water. The strength of the dissociation depends on the strength of the electrolyte properties. The stronger it is, the more ions will dissociate
Reaction
Li₂S⇒2Li⁺+S²⁻
mol ratio Li₂S : Li⁺: S²⁻ = 1 : 2 : 1
so the lithium-ion (Li⁺) concentration :
