Here are the names of the given compounds:
- Ca(C2H3O2)2: Calcium acetate
- PCl3: Phosphorus trichloride
- Cu(MnO4)2: Copper(II) permanganate
- Fe2(CO3)3: Iron(III) carbonate
- LiHCO3: Lithium bicarbonate
- Cr2S3: Chromium(III) sulfide
- Ca(CN)2: Calcium cyanide
Explanation:
- Calcium acetate is formed by calcium ions (Ca²⁺) and acetate ions (C2H3O2⁻).
- Phosphorus trichloride consists of one phosphorus atom and three chlorine atoms.
- Copper(II) permanganate contains copper ions (Cu²⁺) and permanganate ions (MnO4⁻).
- Iron(III) carbonate is composed of iron ions (Fe³⁺) and carbonate ions (CO3²⁻).
- Lithium bicarbonate includes lithium ions (Li⁺) and bicarbonate ions (HCO3⁻).
- Chromium(III) sulfide is made up of chromium ions (Cr³⁺) and sulfide ions (S²⁻).
- Calcium cyanide consists of calcium ions (Ca²⁺) and cyanide ions (CN⁻).
