Name the following compounds: a) Ca(C2H3O2)2, b) PCl3, c) Cu(MnO4)2, d) Fe2(CO3)3, e) LiHCO3, f) Cr2S3, g) Ca(CN)2

Here are the names of the given compounds:

1. Ca(C2H3O2)2: Calcium acetate
2. PCl3: Phosphorus trichloride
3. Cu(MnO4)2: Copper(II) permanganate
4. Fe2(CO3)3: Iron(III) carbonate
5. LiHCO3: Lithium bicarbonate
6. Cr2S3: Chromium(III) sulfide
7. 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⁻).
