On strong heating of `CaO` and `C`, the products formed are

Options

A. `Ca and CO`
B. `CaC_(2) and CO`
C. `Ca(OH)_(2)`
D. `CaC_(2) and CO_(2)`

Explanation

To solve the question regarding the products formed on strong heating of `CaO` (calcium oxide) and `C` (carbon), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in this reaction are calcium oxide (CaO) and carbon (C).

2. **Understand the Reaction Conditions**: The question specifies that the heating is strong, which indicates that the reaction will likely proceed to completion, leading to the formation of products.

3. **Predict the Reaction**: When calcium oxide is heated with carbon, a reduction reaction occurs. Calcium oxide, being an oxide of a highly electropositive metal (calcium), does not easily undergo reduction by carbon. Instead, it reacts with carbon to form calcium carbide (CaC₂) and carbon monoxide (CO).

4. **Write the Balanced Chemical Equation**:
The balanced chemical equation for the reaction is:
\[ \text{CaO} + 2\text{C} \rightarrow \text{CaC}_2 + \text{CO} \]
This shows that one mole of calcium oxide reacts with two moles of carbon to produce one mole of calcium carbide and one mole of carbon monoxide.

5. **Conclusion**: The products formed from the strong heating of calcium oxide and carbon are calcium carbide (CaC₂) and carbon monoxide (CO).

### Final Answer:
The products formed are calcium carbide (CaC₂) and carbon monoxide (CO).
