On heating copper nitrate strongly the compound obtained is

Options

A. Copper
B. Copper oxide
C. Copper nirtite
D. Copper nitride

Explanation

To solve the question "On heating copper nitrate strongly the compound obtained is", we will follow these steps:

### Step 1: Identify the compound
We start with copper nitrate, which has the chemical formula Cu(NO₃)₂.

### Step 2: Understand the decomposition process
When copper nitrate is heated strongly, it undergoes thermal decomposition. This means that the compound breaks down into simpler substances.

### Step 3: Write the decomposition reaction
The decomposition of copper nitrate can be represented by the following chemical equation:
\[ 2 \text{Cu(NO}_3\text{)}_2 \rightarrow 2 \text{CuO} + 4 \text{NO}_2 + \text{O}_2 \]
This equation shows that copper nitrate decomposes into copper oxide (CuO), nitrogen dioxide (NO₂), and oxygen gas (O₂).

### Step 4: Identify the main product
From the decomposition reaction, we can see that one of the main products formed is copper oxide (CuO).

### Step 5: Conclusion
Therefore, the compound obtained on heating copper nitrate strongly is copper oxide.

### Final Answer
The correct answer is **Option B: Copper oxide**.
