TestHub · Accepted Answer

The question asks to identify the number of ores listed that contain a metal in the +1 oxidation state. Let's analyze each ore:

1. Copper pyrite: $C u F e S_{2}$ .( Cu₂S + FeS + FeS₂). Copper in +1 oxidation state.

2. Chalcocite: $C u_{2} S$ . Copper is in the +1 oxidation state.

3. Chile Saltpetre: $N a N O_{3}$ . Sodium is in the +1 oxidation state.

4. Cryolite: $N a_{3} A l F_{6}$ . Sodium is in the +1 oxidation state.

5. Cuprite: $C u_{2} O$ . Copper is in the +1 oxidation state.

6. Sylvine: $K Cl$ . Potassium is in the +1 oxidation state.
