On heating calcium acetate and calcium formate, the product formed is :

Options

A. `CH_3 COCH_3`
B. `CH_3 CHO`
C. `HCHO + CaCO_3`
D. `CH_3 CHO + CaCO_3`

Explanation

To solve the problem of what products are formed when heating calcium acetate and calcium formate, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this case are calcium acetate and calcium formate.

- **Calcium Acetate** has the formula \( \text{Ca(C}_2\text{H}_3\text{O}_2\text{)}_2 \) or can be represented as \( \text{Ca(CH}_3\text{COO)}_2 \).
- **Calcium Formate** has the formula \( \text{Ca(HCOO)}_2 \).

### Step 2: Understand the Heating Process
When calcium acetate and calcium formate are heated, they undergo thermal decomposition.

### Step 3: Write the Decomposition Reactions
1. **Decomposition of Calcium Acetate**:
\[ \text{Ca(C}_2\text{H}_3\text{O}_2\text{)}_2 \rightarrow \text{CaCO}_3 + \text{CH}_4 + \text{CO}_2 \]
(Note: The products can vary depending on the conditions, but typically carbon dioxide and methane are released.)

2. **Decomposition of Calcium Formate**:
\[ \text{Ca(HCOO)}_2 \rightarrow \text{CaCO}_3 + \text{H}_2 + \text{CO} \]
(This reaction also produces calcium carbonate along with hydrogen and carbon monoxide.)

### Step 4: Combine the Reactions
When both reactants are heated together, the overall reaction can be summarized as:
\[ \text{Ca(C}_2\text{H}_3\text{O}_2\text{)}_2 + \text{Ca(HCOO)}_2 \rightarrow 2 \text{CaCO}_3 + \text{CH}_4 + \text{CO} + \text{H}_2 \]

### Step 5: Identify the Main Products
From the combined reactions, the main products formed upon heating calcium acetate and calcium formate are:
- Calcium Carbonate (\( \text{CaCO}_3 \))
- Methane (\( \text{CH}_4 \))
- Carbon Monoxide (\( \text{CO} \))
- Hydrogen (\( \text{H}_2 \))

### Final Answer
The products formed on heating calcium acetate and calcium formate are:
- Calcium Carbonate (\( \text{CaCO}_3 \))
- Methane (\( \text{CH}_4 \))
- Carbon Monoxide (\( \text{CO} \))
- Hydrogen (\( \text{H}_2 \))
