A mixture of calcium acetate and calcium formate on heating gives

Options

A. `CH_(3)COCH_(3)`
B. `CH_(3)CH_(2)NH_(2)`
C. `HCHO`
D. all of these

Explanation

To solve the question regarding the heating of a mixture of calcium acetate and calcium formate, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compounds**:
- Calcium acetate has the formula \( \text{Ca(C}_2\text{H}_3\text{O}_2)_2 \).
- Calcium formate has the formula \( \text{Ca(HCOO)}_2 \).

2. **Write the Reaction**:
- When heated, calcium acetate and calcium formate undergo a decomposition reaction. The general reaction can be represented as:
\[ \text{Ca(C}_2\text{H}_3\text{O}_2)_2 + \text{Ca(HCOO)}_2 \xrightarrow{\text{heat}} \text{Products} \]

3. **Decomposition Products**:
- Calcium acetate decomposes to produce calcium carbonate (\( \text{CaCO}_3 \)) and acetaldehyde (\( \text{CH}_3\text{CHO} \)).
- Calcium formate decomposes to produce calcium carbonate (\( \text{CaCO}_3 \)) and formaldehyde (\( \text{HCHO} \)).

4. **Combine the Products**:
- From the reaction of calcium acetate, we get:
\[ \text{Ca(C}_2\text{H}_3\text{O}_2)_2 \rightarrow \text{CaCO}_3 + \text{CH}_3\text{CHO} \]
- From the reaction of calcium formate, we get:
\[ \text{Ca(HCOO)}_2 \rightarrow \text{CaCO}_3 + \text{HCHO} \]

5. **Final Products**:
- Since both reactions produce calcium carbonate, we can combine the results:
- Total calcium carbonate produced = \( 2 \text{CaCO}_3 \)
- Total organic products = Acetaldehyde and Formaldehyde.

6. **Conclusion**:
- The main products from heating a mixture of calcium acetate and calcium formate are:
- Acetaldehyde (\( \text{CH}_3\text{CHO} \))
- Formaldehyde (\( \text{HCHO} \))
- Calcium carbonate (\( \text{CaCO}_3 \))

### Final Answer:
On heating a mixture of calcium acetate and calcium formate, the products formed are acetaldehyde, formaldehyde, and calcium carbonate.
