Answer
The balanced equation for the reaction between copper carbonate and dilute sulfuric acid can be written as:
CuCO3+H2SO4→CuSO4+CO2+H2O

Answer
To calculate the relative formula mass of CuCO₃, we sum the atomic masses of its constituent elements:
Copper (Cu): 63.5
Carbon (C): 12.0
Oxygen (O): 16.0 × 3 = 48.0
Now, adding these together:
63.5+12.0+48.0=123.5
Thus, the relative formula mass of copper carbonate (CuCO₃) is 123.5.

Answer
To test for carbon dioxide, the following method can be used:
A: Bubble the gas through limewater; if it turns cloudy, this indicates the presence of carbon dioxide.
