What mass of copper oxide will will be obtained by heating 12.35 g of copper carbonate ? (Atomic mass of Cu = 63.5).

Explanation

To find the mass of copper oxide obtained by heating 12.35 g of copper carbonate, we will follow these steps:

### Step 1: Write the chemical reaction
When copper carbonate (CuCO₃) is heated, it decomposes into copper oxide (CuO) and carbon dioxide (CO₂). The balanced chemical equation for this reaction is:
\[ \text{CuCO}_3 \rightarrow \text{CuO} + \text{CO}_2 \]

### Step 2: Calculate the molar mass of copper carbonate (CuCO₃)
To calculate the molar mass of copper carbonate, we need to sum the atomic masses of its constituent elements:
