nomenclature is fun! i cant wait for the quiz!
i will ace this quiz!

Explanation:

Let's solve the naming of these chemical compounds one by one (we'll do a few as examples, and you can follow the same rules for others):

Compound 22: $\ce{Ag3PO4}$

Step1: Identify ions

$\ce{Ag+}$ (silver ion) and $\ce{PO4^3-}$ (phosphate ion).

Step2: Balance charges

3 $\ce{Ag+}$ (each +1) balance 1 $\ce{PO4^3-}$ ( - 3).

Step3: Name the compound

Cation (silver, no charge to specify as Ag is +1 here) + anion (phosphate). So name is Silver Phosphate.

Compound 23: $\ce{Hg(ClO3)2}$

Step1: Identify ions

$\ce{Hg^{2+}}$ (mercury(II) ion, since 2 $\ce{ClO3-}$ (each - 1) so Hg is +2) and $\ce{ClO3-}$ (chlorate ion).

Step2: Name the compound

Cation (mercury(II)) + anion (chlorate). So name is Mercury(II) Chlorate.

Compound 24: $\ce{P2O3}$

Step1: Identify type (covalent)

Non - metal + non - metal, so use prefixes.

Step2: Prefixes and elements

P: 2 (di - ), O: 3 (tri - ). Name: Diphosphorus Trioxide.

Compound 25: $\ce{K2SO3}$

Answer:

Step1: Identify ions

$\ce{NH4+}$ (ammonium ion) and $\ce{NO3-}$ (nitrate ion).

Step2: Balance charges

1 $\ce{NH4+}$ ( + 1) balances 1 $\ce{NO3-}$ ( - 1).

Step3: Name the compound

Cation (ammonium) + anion (nitrate). So name is Ammonium Nitrate.

For the initially answered (but with some errors) compounds:

• $\ce{Fe(OH)2}$: Correct name is Iron(II) Hydroxide (your initial "Iron(2) hydroxide" has non - standard notation, should be Iron(II) Hydroxide).
• $\ce{(NH4)3PO4}$: Correct name is Ammonium Phosphate (your "Ammoninm Phosphanc" has spelling errors, correct anion is phosphate).
• $\ce{AlPO4}$: Correct name is Aluminum Phosphate (your "Aluminum Phosphanc" has wrong anion name, it's phosphate).
• $\ce{Na3PO3}$: Correct name is Sodium Phosphite (your "Sodium Phosphite" is correct in ion part, just ensure spelling).
• $\ce{Cu(C2H3O2)2}$: Correct name is Copper(II) Acetate (your "copper(2) acetate" has non - standard capitalization and notation, should be Copper(II) Acetate).
• $\ce{CaCO3}$: Your "calcium carbonate" is correct.
• $\ce{Fe2O3}$: Correct name is Iron(III) Oxide (your "Iron(3) oxide" has non - standard notation, should be Iron(III) Oxide).
• $\ce{FeO}$: Correct name is Iron(II) Oxide (your "Iron(2) oxide" has non - standard notation, should be Iron(II) Oxide).
• $\ce{NH4OH}$: Correct name is Ammonium Hydroxide (your "Ammonium hydroxide" is correct in name, just capitalization).
• $\ce{Si(SO4)2}$: Correct name is Silicon(IV) Sulfate (since Si is +4 to balance 2 $\ce{SO4^2-}$ (total - 4), your "Silicon(4) sulfate" has non - standard notation, should be Silicon(IV) Sulfate).

Final Answers for the new compounds (22 - 31):

1. Silver Phosphate
2. Mercury(II) Chlorate
3. Diphosphorus Trioxide
4. Potassium Sulfite
5. Magnesium Chloride
6. Zinc Fluoride
7. Magnesium Sulfate
8. Calcium Carbonate
9. Sodium Hydroxide
10. Ammonium Nitrate

And the corrected names for the initially answered (12 - 21) with errors:

1. Iron(II) Hydroxide
2. Ammonium Phosphate
3. Aluminum Phosphate
4. Copper(II) Acetate
5. Iron(III) Oxide
6. Iron(II) Oxide
7. Silicon(IV) Sulfate
