Explanation:

Response
Question 12: $\boldsymbol{Fe(OH)_2}$

Step1: Identify cation and anion

Cation: $\text{Fe}^{2+}$ (Iron(II) ion, since the subscript of $\text{OH}^-$ is 2, so charge of Fe is +2). Anion: $\text{OH}^-$ (Hydroxide ion).

Step2: Name the compound

Name the cation first, then the anion. For transition metals with variable charges, use Roman numerals to indicate the charge. So it's Iron(II) hydroxide.

Step1: Identify cation and anion

Cation: $\text{NH}_4^+$ (Ammonium ion). Anion: $\text{PO}_4^{3-}$ (Phosphate ion).

Step2: Name the compound

Name the cation first, then the anion. So it's Ammonium phosphate.

Step1: Identify cation and anion

Cation: $\text{Al}^{3+}$ (Aluminum ion, charge is +3 as Al is in group 13). Anion: $\text{PO}_4^{3-}$ (Phosphate ion).

Step2: Name the compound

Name the cation first, then the anion. So it's Aluminum phosphate.

Answer:

Iron(II) hydroxide

Question 13: $\boldsymbol{(NH_4)_3PO_4}$
