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.
The colour of copper(II) oxide is black, while that of copper(I) oxide is red. The green colour you see on the Statue of Liberty is because carbon dioxide in the air reacted with the copper to produce copper(II) carbonate, which is greenish-blue.
Copper doesn't react with carbon dioxide at room temperature.
Endothermic because thermal decomposition is the breakdown of a compound using heat. Remember endo means more energy is taken in breaking the bonds of copper carbonate than there is given out when making the bonds of copper oxide and carbon dioxide.
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.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
This compound is the copper(II) oxide, CuO.
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
on heating copper carbonate decomposes to cupric oxide which is black in colour.
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.
It is possible for carbon dioxide and copper oxide to encourage a reaction to take place due to thermal composition. When calcium carbonate is heated, it decomposes and generates carbon dioxide and copper oxide.
The colour of copper(II) oxide is black, while that of copper(I) oxide is red. The green colour you see on the Statue of Liberty is because carbon dioxide in the air reacted with the copper to produce copper(II) carbonate, which is greenish-blue.
if mixed with air it explodes with a bus off light i did it in science last week 31/10/08 stefan rabicano
copperCopper (cupric) oxide is produced. Therefore, copper is the metal that produces a black oxide when heated.
