Question

part 1 (0.7 point)
cucl₂
choose one or more:
copper is the cation.
copper is the anion.
chlorine is the cation.
chlorine is the anion.
it would be named as a molecular compound.
it would be named as an acid.

part 2 (0.7 point)
ca₃(po₄)₂
choose one or more:
calcium is the cation
calcium is the anion.
phosphorus is the cation.
phosphorus is the anion.
oxygen is the cation.
oxygen is the anion.

Explanation:

Step1: Recall ion - naming rules for $CuCl_2$

In $CuCl_2$, copper (Cu) is a metal and forms a positive ion (cation), and chlorine (Cl) is a non - metal and forms a negative ion (anion). Also, $CuCl_2$ is an ionic compound, not a molecular compound or an acid.

Step2: Recall ion - naming rules for $Ca_3(PO_4)_2$

In $Ca_3(PO_4)_2$, calcium (Ca) is a metal and forms a positive ion (cation). The poly - atomic ion $PO_4^{3 - }$ is the anion, where phosphorus and oxygen are part of the poly - atomic anion and not cations.

Answer:

Part 1:
A. Copper is the cation.
D. Chlorine is the anion.
Part 2:
A. Calcium is the cation.
