If you're talking about thermal decomposition then the answer is Calcium Oxide (s)
Thermal decomposition of calcium carbonate release calcium oxide (CaO).
Calcium oxide is formed in a blast furnace as a byproduct of the smelting process when limestone, which contains calcium carbonate, is added to the furnace. The intense heat of the furnace decomposes the calcium carbonate into calcium oxide and carbon dioxide. The calcium oxide is then collected as a solid residue.
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
If you're talking about thermal decomposition then the answer is Calcium Oxide (s)
The solid particles formed by the reaction of sodium carbonate and calcium chloride are white in color.
The precipitate formed when mixing calcium chloride and sodium carbonate is called calcium carbonate. It is a white solid that forms when calcium ions (from calcium chloride) react with carbonate ions (from sodium carbonate) to produce an insoluble salt.
Two methods of decomposition. Thermal Decomposition. Heat calcium carbonate to 'red glowing heat' and it decomposes into calcium oxide ((Quick)Lime) and Carbon Dioxide. CaCO3 ==heat==> CaO(s) + CO2(g). Acid Dissolution. Dissolve in any acid. It decomposes into calcium chloride, water and carbon dioxide. CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(g)
It decomposes into calcium oxide and carbon dioxide...
This would give: decomposes Ca(CO3)2 (s) --------------------CaO(s)+3CO2(g)
When zinc carbonate decomposes, it produces zinc oxide (ZnO) as a solid along with carbon dioxide gas (CO2).
To make calcium carbonate at home, you can mix calcium chloride and sodium carbonate in water. This will cause a chemical reaction that forms calcium carbonate as a solid precipitate. Filter out the solid and let it dry to obtain calcium carbonate.
Calcium carbonate has a solubility of 0.0006g per 100g of water at standard temperatures so the precipitate formed will be that. Sodium Chloride is very soluble, with 35.9g per 100g of water.
