Question

Write the molecular formulae of all the compounds that can be formed by the combination of the following ions. Cu²+, Na+, Fe³+, Cl-, SO4², PO4³-​

Answer 1

Here are the molecular formulas of all the possible compounds that can be formed by combining the given ions:

1. Copper (II) chloride: CuCl2
2. Sodium sulfate: Na2SO4
3. Iron (III) sulfate: Fe2(SO4)3
4. Sodium phosphate: Na3PO4
5. Copper (II) sulfate: CuSO4
6. Sodium chloride: NaCl
7. Iron (III) phosphate: FePO4
8.Copper(I) sulfide :Cu₂S

Note:
- The subscript following each element in a compound represents how many atoms of that element there are in one molecule of the compound.
- When writing chemical formulas, we always write the cation first, followed by anion second
