Sure, we will classify each solid into either amorphous or crystalline based on their characteristics.
1. Emerald:
- Classification: Crystalline
- Reason: Emerald is a gemstone that has a well-defined crystal structure.
2. Glass:
- Classification: Amorphous
- Reason: Glass does not have a regular crystal structure; its atoms are arranged randomly which is characteristic of amorphous solids.
3. MoCl2 (Molybdenum Dichloride):
- Classification: Crystalline
- Reason: MoCl2 forms a solid with a well-defined crystal lattice, indicative of a crystalline solid.
4. Rubber:
- Classification: Amorphous
- Reason: Rubber has an irregular arrangement of molecules, typical of amorphous solids.
So, the classifications for the given solids are:
- Emerald: Crystalline
- Glass: Amorphous
- MoCl2: Crystalline
- Rubber: Amorphous
