Simple glass is a mixture of which of the following?

Options

A. Silica
B. Sodium silicate
C. Calcium silicate
D. All three of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Simple Glass**: Simple glass, commonly referred to as ordinary glass, is primarily an amorphous solid. This means that its particles are not arranged in a regular pattern, unlike crystalline solids.

2. **Components of Simple Glass**: The main components that make up simple glass are:
- **Silica (SiO2)**: This is the primary ingredient, making up about 75% of the glass. Silica is responsible for the glass's structure and transparency.
- **Soda (Sodium Oxide, Na2O)**: This is derived from soda ash and is used to lower the melting point of silica, making it easier to work with.
- **Lime (Calcium Oxide, CaO)**: This is added to improve the durability and chemical resistance of the glass.

3. **Conclusion**: Therefore, simple glass is a mixture of silica (SiO2), sodium oxide (Na2O), and calcium oxide (CaO).

**Final Answer**: Simple glass is a mixture of silica (SiO2), sodium oxide (Na2O), and calcium oxide (CaO).
