Copper(II) carbonate (green copper caebonate): desintegrates into solid black copper(II) oxide and gaseous carbon dioxide.
CuCO3 --[heat]--> CuOsolid + CO2,gas
Some metal carbonates decompose more easily due to their place on the reactivity series, ie the more reactive the metal, the harder it is to decompose e.g. Sodium and Potassium Carbonates are harder to decompose than Lead or Copper carbonates.
All carbonates decompose on heating: examples are sodium carbonate, calcium carbonate, potassium carbonate, uranyl carbonate, magnesium carbonate.
Because some are more rective than others, the ones that are reactive decompose slower because they hod onto there ores.
A metal that's an elemental metal (rather than a mixture like brass or solder), can't decompose. It's already in its least complicated state.

AlΒ2(CO3)3 --> Al2O3 + 3CO2
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
It decomposes into calcium oxide and carbon dioxide...
NH3 and CO2
silver carbonate decomposes into silver (1) oxide and carbon dioxide Ag2CO3-->Ag2O + CO2 Because both sides are equal you do not have to balance the equation. note: Because silver is a transitional metal you had the choice between silver (3) and silver (1). I decided to choose Silver (1) because that meant that the silver carbonate was completely decomposed and also it is easier to balance the equation.
When calcium carbonate is heated, it breaks down by thermal decomposition to carbon dioxide & calcium oxide (quicklime). Here is the word equation: Calcium carbonate --> Calcium oxide + Carbon dioxide Here is the chemical equation: CaCO3 (s) --> CaO (s) + CO2 (g)
It decomposes into calcium oxide and carbon dioxide
CaCo3 heated & gives CaO+Co2
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
Because it decomposes to form carbon dioxide and barium oxide.
on heating copper carbonate decomposes to cupric oxide which is black in colour.
It decomposes into Sodium oxide and Carbon dioxide.Na2CO3 --Δ--> Na2O + CO2
the metal carbonate decomposes into a metal oxide and carbon dioxide
Another term for baking soda is sodium hydrogen carbonate or sodium bicarbonate. When it is heated, it decomposes to yield carbon dioxide, water and a carbonate salt.
Ammonium Carbonate decomposes to yield Water(H2O), Carbon Dioxide(CO2), and Ammonium(NH4).
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
Experimentally to prove that, capture the gas and pass it through lime water. If the lime water turns milky then the gas is CO2 . Or an example of equation for decomposition of a metal carbonate is :- MgCO3 + heat ------> MgO + CO2
Sodium bicarbonate decomposes into sodium carbonate, carbon dioxide, and water.
