Step5: Analyze ammonium sulfide

- Ionic (polyatomic ion + nonmetal ion). Ammonium $\text{NH}_4^+$, sulfide $\text{S}^{2-}$. Charge balance: 2*1+ + (-2) = 0. Formula: $(\text{NH}_4)_2\text{S}$. Type: Ionic.

Step6: Analyze aluminum cyanide

Step7: Analyze carbon disulfide

- Covalent (two nonmetals). Carbon (C), disulfide (2 S). Formula: $\text{CS}_2$. Type: Covalent.

Step8: Analyze tetraphosphorous pentoxide

- Covalent (two nonmetals). Tetraphosphorous (4 P), pentoxide (5 O). Formula: $\text{P}_4\text{O}_5$ (wait, typo? Tetraphosphorus pentoxide is $\text{P}_4\text{O}_{10}$? Wait, "tetraphosphorous pentoxide" – maybe error, but standard is $\text{P}_4\text{O}_{10}$ (pentoxide would be 5 O? No, penta- is 5, but $\text{P}_4\text{O}_5$? Wait, original name: tetraphosphorous pentoxide – P₄O₅? Or maybe $\text{P}_4\text{O}_{10}$ (tetraphosphorus decoxide). Wait, maybe typo. Assuming "pentoxide" (5 O), formula $\text{P}_4\text{O}_5$. Type: Covalent.

Step9: Analyze potassium permanganate

- Ionic (metal + polyatomic ion). Potassium $\text{K}^+$, permanganate $\text{MnO}_4^-$. Formula: $\text{KMnO}_4$. Type: Ionic.

Step12: Analyze carbon monoxide

- Covalent (two nonmetals). Carbon (C), monoxide (1 O). Formula: $\text{CO}$. Type: Covalent.

Step13: Analyze potassium oxide

- Ionic (metal + nonmetal). Potassium $\text{K}^+$, oxide $\text{O}^{2-}$. Charge balance: 2*1+ + (-2) = 0. Formula: $\text{K}_2\text{O}$. Type: Ionic.
