1. ca(oh)₂
2. baf₂
3. fe(no₃)₂
4. cf₄
5. n₂o₃
6. p₂o₃
7. mns₂
8. li₃p
9. cu(so₄)
10. ch₄
11. n₂o

Explanation:

Step1: Analyze \(Ca(OH)_2\)

First element is \(Ca\) (not \(H\)), has \(>2\) elements (\(Ca\), \(O\), \(H\)). \(Ca\) is a metal (not transition), use polyatomic chart (\(OH^-\) is hydroxide). Name: Calcium hydroxide.

Step2: Analyze \(BaF_2\)

First element \(Ba\) (not \(H\)), 2 - element compound. \(Ba\) is a metal (not transition). Ends with - ide. Name: Barium fluoride.

Step3: Analyze \(Fe(NO_3)_2\)

First element \(Fe\) (not \(H\)), \(>2\) elements (\(Fe\), \(N\), \(O\)). \(Fe\) is a transition metal. Use polyatomic chart (\(NO_3^-\) is nitrate). Name: Iron (II) nitrate.

Step4: Analyze \(CF_4\)

First element \(C\) (not metal). Compound is covalent. Use prefixes (\(C\) - carbon, \(F\) - fluoride, 4 - tetra). Name: Carbon tetrafluoride.

Step5: Analyze \(N_2O_3\)

First element \(N\) (not metal). Compound is covalent. Use prefixes (\(N\) - nitrogen, \(O\) - oxide, 2 - di, 3 - tri). Name: Dinitrogen trioxide.

Step6: Analyze \(P_2O_3\)

First element \(P\) (not metal). Compound is covalent. Use prefixes (\(P\) - phosphorus, \(O\) - oxide, 2 - di, 3 - tri). Name: Diphosphorus trioxide.

Step7: Analyze \(MnS_2\)

First element \(Mn\) (transition metal). 2 - element compound. Ends with - ide. Name: Manganese (IV) sulfide.

Step8: Analyze \(Li_3P\)

First element \(Li\) (not \(H\), not transition metal). 2 - element compound. Ends with - ide. Name: Lithium phosphide.

Step9: Analyze \(Cu(SO_4)\)

First element \(Cu\) (transition metal). \(>2\) elements (\(Cu\), \(S\), \(O\)). Use polyatomic chart (\(SO_4^{2 -}\) is sulfate). Name: Copper (II) sulfate.

Step10: Analyze \(CH_4\)

First element \(C\) (not metal). Compound is covalent. Use prefixes (\(C\) - carbon, \(H\) - hydride, 4 - tetra). Name: Carbon tetrahydride (methane is also common).

Step11: Analyze \(N_2O\)

First element \(N\) (not metal). Compound is covalent. Use prefixes (\(N\) - nitrogen, \(O\) - oxide, 2 - di). Name: Dinitrogen monoxide.

1. Calcium hydroxide
2. Barium fluoride
3. Iron (II) nitrate
4. Carbon tetrafluoride
5. Dinitrogen trioxide
6. Diphosphorus trioxide
7. Manganese (IV) sulfide
8. Lithium phosphide
9. Copper (II) sulfate
10. Carbon tetrahydride (or methane)
