Answer

The balanced equation for the reaction is:

ext{CuCO}_3 + ext{H}_2 ext{SO}_4 → ext{CuSO}_4 + ext{CO}_2 + ext{H}_2 ext{O}

Answer

To calculate the relative formula mass of copper carbonate (CuCO₃), we sum the atomic masses of its components:

Copper (Cu) = 63.5
Carbon (C) = 12.0
Oxygen (O) = 16.0 × 3 = 48.0

Thus, the calculation is:

ext{Relative formula mass of CuCO}_3 = 63.5 + 12.0 + 48.0 = 123.5
