Carbonate by itself is an ion that does not contain copper and therefore could not produce copper if heated. However, because carbonate is a negatively charged ion, no substantial number of carbonate ions can exist stably except in association with an equal number of positively charged cations to neutralize the electrical charge of the carbonate ions. If these cations are cations of copper, then copper oxide can be produced by heating the copper carbonate salt.
CuCO3 is bluish-greenish-white. If it is heated to a high enough temperature, it will decompose into Carbon Dioxide and Copper II Oxide, which is black.
Either sodium carbonate or copper carbonate
carbon dioxide [CuCO3 --> CuO + CO2]
Because it undergoes thermal decomposition. If you give heat to Copper (II) carbonate, it will decompose to form Copper (II) oxide. Instead of saying green copper carbonate, I guess it is safer and better to say copper (II) carbonate.
Copper doesn't react with carbon dioxide at room temperature.
When copper carbonate is heated, it changes from its green color to black copper oxide.
When copper carbonate is heated, it decomposes into copper oxide, releasing carbon dioxide gas. The remaining ionic compound is copper oxide (CuO).
When copper carbonate is heated, it decomposes to form copper oxide and carbon dioxide gas, leaving behind copper oxide residue. When copper carbonate is mixed with acids to produce copper salts, a blue residue may be left behind.
This compound is the copper(II) oxide, CuO.
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
When copper(II) carbonate is heated, it decomposes to form copper(II) oxide and carbon dioxide. The ionic compound that remains is copper(II) oxide, which has the chemical formula CuO.
CuCO3 is bluish-greenish-white. If it is heated to a high enough temperature, it will decompose into Carbon Dioxide and Copper II Oxide, which is black.
When copper carbonate is heated, a thermal decomposition reaction occurs. This reaction causes copper carbonate to break down into copper oxide and carbon dioxide gas, which is released as a byproduct.
Either sodium carbonate or copper carbonate
carbon dioxide [CuCO3 --> CuO + CO2]
When malachite is heated, it decomposes into copper(II) oxide and carbon dioxide. The word equation for this reaction is: Copper(II) carbonate (malachite) → Copper(II) oxide + Carbon dioxide.
