Question

this question has two parts. first, answer part a. then, answer part b.
part a
what is the name of the binary compound for the formula cacl2?
options: calcium chlorine, calcium chloride, calcium boronite, calcium hypochlorate

Explanation:

To name binary ionic compounds, we use the name of the cation (metal) first, then the anion (non - metal) with its ending changed to -ide. In \(CaCl_2\), the cation is calcium (\(Ca^{2 +}\)) and the anion is chloride (from chlorine, \(Cl^-\)). "Calcium chlorine" is incorrect as we use the -ide suffix for the anion. "Calcium boronite" is wrong because the anion here is chloride, not related to boron. "Calcium hypochlorate" is for a compound with the hypochlorite ion (\(ClO^-\)), not \(Cl^-\). So the correct name is calcium chloride.

Answer:

B. calcium chloride
