I would start with writing the chemical formulas. For instance, barium bromide BaBr2
it has three ions.
I will be happy to critique your work.
ammonium sulfite
ammonium perchlorate
cadmium phosphate
ammonium iodate
ammonium sulfate
barium bromide
none
How can u tell???
it has three ions.
I will be happy to critique your work.
Let's go through each compound and identify the ions:
1. Ammonium sulfite: The ions in this compound are ammonium (NH4+) and sulfite (SO3^2-). There is one anion present.
2. Ammonium perchlorate: The ions in this compound are ammonium (NH4+) and perchlorate (ClO4-). There is one anion present.
3. Cadmium phosphate: The ions in this compound are cadmium (Cd^2+) and phosphate (PO4^3-). There are three anions present.
4. Ammonium iodate: The ions in this compound are ammonium (NH4+) and iodate (IO3-). There is one anion present.
5. Ammonium sulfate: The ions in this compound are ammonium (NH4+) and sulfate (SO4^2-). There are two anions present.
6. Barium bromide: The ions in this compound are barium (Ba^2+) and bromide (Br-). There is one anion present.
Based on the analysis, Cadmium phosphate is the only compound with three anions present. Therefore, the correct answer is "cadmium phosphate."
