Question

this question has two parts. first, answer part a. then, answer part b.
part a
what is the name of the binary compound of the formula cabr₂?
○ calcium barium
○ calcium bromide
○ calcium boronite
○ calcium bromine
part b

Explanation:

Part A

To name the binary compound \( \text{CaBr}_2 \), we first identify the elements: \( \text{Ca} \) is calcium (a metal) and \( \text{Br} \) is bromine (a non - metal). For binary ionic compounds, we name the metal first, and then the non - metal with its ending changed to -ide. So bromine becomes bromide. So the name of \( \text{CaBr}_2 \) is calcium bromide.

Answer:

B. calcium bromide (assuming the second option is labeled as B, with the text "calcium bromide")

(Note: Since the original options' numbering/labeling (like A, B, C, D) is not fully clear from the image, but based on the content, the correct option is the one with "calcium bromide". If we assume the options are in order and the second option is the correct one, we present it as above. If Part B was provided, we would follow the same process for it.)
