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.
What else can I help you with?
What colour is copper II carbonate when it is 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.
What is a blue solid that produces a black solid when heated?
Either sodium carbonate or copper carbonate
What gas is given off when copper carbonate heated?
carbon dioxide [CuCO3 --> CuO + CO2]
Why does green copper carbonate go black?
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.
When copper oxide is heated in carbon what is produced?
Copper doesn't react with carbon dioxide at room temperature.
What is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
When copper carbonate is heated what ionic compound remains?
When copper carbonate is heated, it decomposes into copper oxide, releasing carbon dioxide gas. The remaining ionic compound is copper oxide (CuO).
What residue is left behind when copper carbonate is hot or cold?
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.
What is the black solid formed when copper carbonate is heated?
This compound is the copper(II) oxide, CuO.
What color is copper carbonate when heated?
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
What happens to magnesium carbonate copper carbonate zinc carbonate and calcium carbonate when they are heated?
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
What ionic compound remains when copper II carbonate is heated?
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.
What colour is copper II carbonate when it is 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.
What type of reaction occurs when copper carbonate is heated?
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.
What is a blue solid that produces a black solid when heated?
Either sodium carbonate or copper carbonate
What gas is given off when copper carbonate heated?
carbon dioxide [CuCO3 --> CuO + CO2]
What is the word equation when Malachite is heated?
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.
