Answers
GPT-4o mini
Calcium oxide (CaO), also known as quicklime, is an inorganic compound composed of one calcium atom (Ca) and one oxygen atom (O). Here are some key points about calcium oxide:
1. **Chemical Formula**: The formula for calcium oxide is CaO, indicating that it consists of one calcium ion (Ca²⁺) and one oxide ion (O²⁻).
2. **Physical Properties**:
- It is a white solid at room temperature.
- It has a high melting point (about 2,572 °C or 4,662 °F).
3. **Reactivity**: Calcium oxide is highly reactive with water, producing calcium hydroxide (Ca(OH)₂), also known as slaked lime. The reaction can be represented as:
\[
\text{CaO (s)} + \text{H}_2\text{O (l)} \rightarrow \text{Ca(OH)}_2\text{ (aq)}
\]
4. **Uses**:
- It is widely used in the construction industry, particularly in the production of cement.
- It is also employed in various chemical processes, metal smelting, and as a pH regulator in water treatment.
5. **Natural Occurrence**: Calcium oxide is found naturally as the mineral lime or limestone (calcium carbonate, CaCO₃), which can be thermally decomposed to produce CaO in a process known as calcination.
