Select all ionic compounds in which the number of anions present is two.
carbon dioxide
X manganese(II) hydroxide
mercury(II) carbonate
X mercury(II) phosphate
ammonia
sulfur dioxide
Hello,
I know manganese(II) hydroxide mercury(II) phosphate both have two anions, however I am unsure about carbon dioxide and sulfur dioxide. would the oxygens in both cases be considered the anion or am I completely off base with this?
Thank you!
its just the 2nd and 4th one
CO2 is a molecule. SO2 is a molecule. NH3 is a molecule. In the first place, these are not ionic compounds and there is no way to consider the O in CO3 or SO2 or the H in NH3 to be anions. You picked two of the three ionic compounds there. The other compound, HgCO3, although we might consider it to be ionic, the # anions is not two.
Hello!
In ionic compounds, anions are negatively charged ions, meaning they have gained electrons. Typically, anions have a larger atomic radius and are located on the right side of the periodic table.
Now, let's analyze the compounds you mentioned:
1. Carbon dioxide (CO2): This is a covalent compound, not an ionic compound. It consists of two oxygen atoms covalently bonded to a carbon atom. In CO2, there are no ions, so there are no anions present.
2. Manganese(II) hydroxide (Mn(OH)2): This is indeed an ionic compound. It consists of the manganese(II) cation (Mn2+) and two hydroxide anions (OH-). Therefore, the number of anions present in this compound is two.
3. Mercury(II) carbonate (HgCO3): This compound is also ionic. It consists of the mercury(II) cation (Hg2+) and the carbonate anion (CO3^2-). So, there is only one anion present in this compound.
4. Mercury(II) phosphate (Hg3(PO4)2): This compound is ionic as well. It contains the mercury(II) cation (Hg2+) and two phosphate anions (PO4^3-). Therefore, there are two anions in this compound.
5. Ammonia (NH3): Ammonia is a covalent compound, not an ionic one. It consists of one nitrogen atom covalently bonded to three hydrogen atoms. There are no ions, so there are no anions present.
6. Sulfur dioxide (SO2): This compound is also covalent. It consists of one sulfur atom covalently bonded to two oxygen atoms. There are no ions or anions present in this compound.
So, in conclusion, the ionic compounds in which the number of anions present is two are manganese(II) hydroxide and mercury(II) phosphate.
I hope this explanation helps! Let me know if you have any further questions.
