Here’s the classification of each compound by bond type:

1. **CaCl2 (Calcium chloride)** - Ionic bond
- This compound consists of calcium ions (Ca²⁺) and chloride ions (Cl⁻), which form an ionic bond.

2. **NO5 (Nitrogen pentoxide)** - Covalent bond
- Nitrogen pentoxide contains nitrogen and oxygen that share electrons, forming covalent bonds.

3. **MgSO4 (Magnesium sulfate)** - Ionic bond
- Magnesium sulfate consists of magnesium ions (Mg²⁺) and sulfate ions (SO₄²⁻), indicating an ionic bond.

4. **Cu2S3 (Copper(III) sulfide)** - Ionic bond
- In this case, copper (Cu) forms ionic bonds with sulfide ions (S²⁻) to create the compound.

5. **P2O5 (Diphosphorus pentoxide)** - Covalent bond
- This compound is formed by sharing electrons between phosphorus and oxygen atoms, indicating covalent bonds.

To summarize:
- **Ionic Compounds:** CaCl2, MgSO4, Cu2S3
- **Covalent Compounds:** NO5, P2O5
