CuO and CO2 (as a dry gas) has not a pH.
CuO + CO2 -> CuCO3 CuO is copper oxide and is an ionic bond Cu(2+) and O(2-) CuCO3 is also an ionic bond, as one oxygen from copper oxide has joined with the covalently bonded carbon dioxide, CO2, to form carbonate, a polyatomic ion. Cu(2+) and CO3(2-)
CuSO3 + heat = CuO + SO2 so Copper oxide and sulfur dioxide are produced.
CuCO3 ---> CuO + CO2
CuCO3(s)-----heat---->CuO(s)+CO2(g) black
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
Copper doesn't react with carbon dioxide at room temperature.
Heating CuCO3 (copper (II) carbonate) produces carbon dioxide (CO2) and copper oxide (CuO).
CuCO3 = CuO + CO2
no reaction
Yes, that is correct. When copper carbonate (CuCO3) is heated, it decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2).
CuO + CO2 -> CuCO3 CuO is copper oxide and is an ionic bond Cu(2+) and O(2-) CuCO3 is also an ionic bond, as one oxygen from copper oxide has joined with the covalently bonded carbon dioxide, CO2, to form carbonate, a polyatomic ion. Cu(2+) and CO3(2-)
Here are the equations for the thermal decomposition of copper carbonate (notice that a metal oxide is formed, just as it was with calcium carbonate): Copper carbonate → copper oxide + carbon dioxide CuCO3 → CuO + CO2
CuSO3 + heat = CuO + SO2 so Copper oxide and sulfur dioxide are produced.
carbon dioxide [CuCO3 --> CuO + CO2]
CuCO3 ---> CuO + CO2
CuCO3(s)-----heat---->CuO(s)+CO2(g) black
As CO2 is added to water, the pH usually decreases.
