CuCO3(s)-----heat---->CuO(s)+CO2(g)
black
Yes, the reaction between hydrochloric acid and copper carbonate is exothermic. This means that it releases heat during the reaction.
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
The reaction of making copper oxide from copper carbonate is endothermic because it requires heat to break the chemical bonds in the reactants and form the products. This means that energy is absorbed from the surroundings during the reaction.
Copper Carbonate
Copper carbonate would precipitate if you combined solutions of copper (II) chloride and sodium carbonate.
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.
Yes, the reaction between hydrochloric acid and copper carbonate is exothermic. This means that it releases heat during the reaction.
copper(II) carbonate or cupric carbonate
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
The compound you are referring to is copper carbonate, which has the chemical formula CuCO3. It is also known as copper(II) carbonate and is commonly found in nature as the mineral malachite.
The reaction of making copper oxide from copper carbonate is endothermic because it requires heat to break the chemical bonds in the reactants and form the products. This means that energy is absorbed from the surroundings during the reaction.
Copper Carbonate
When copper carbonate reacts with potassium, it forms copper metal and potassium carbonate. This reaction is a redox reaction where copper is reduced and potassium is oxidized.
Heating copper carbonate (CuCO3) should result in the generation of copper oxide (CuO) and carbon dioxide gas (CO2). Therefore, the weight (mass) of the material remaining should decrease by an amount equal to the mass of CO2 lost. If the mass didn't change, you didn't heat the copper carbonate sufficiently to cause the decomposition.
Copper carbonate would precipitate if you combined solutions of copper (II) chloride and sodium carbonate.
The precipitate formed when copper sulfate and sodium carbonate are mixed is copper carbonate. This reaction occurs because copper carbonate is insoluble in water and therefore forms a solid precipitate.
