on heating copper carbonate decomposes to cupric oxide which is black in colour.
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
Yes, that is correct. When copper carbonate (CuCO3) is heated, it decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2).
The metal powder that turns black when heated in an open dish is likely to be magnesium. This is due to the formation of magnesium oxide on the surface of the metal powder when it reacts with oxygen in the air during heating.
Porcelain turns black when heated due to carbon impurities in the material being burned off, leaving behind a black residue. This happens at high temperatures where the carbon particles react and create black pigments on the surface of the porcelain.
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
CuCO3 = CuO + CO2
When CuCO3 is heated, it decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2) gas. This is a decomposition reaction where the solid CuCO3 breaks down into a solid and a gas when heated.
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.
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2

As a heated liquid turns into a gas, it ... ?
The symbol for the reaction that occurs when copper carbonate is heated is: CuCO3(s) → CuO(s) + CO2(g)
When heated, copper(II) carbonate (CuCO3) will decompose to form copper(II) oxide (CuO), carbon dioxide (CO2), and oxygen gas (O2). A wooden splint will continue to burn in the presence of the oxygen gas, producing carbon dioxide and water vapor as it undergoes combustion.
