metal oxide and carbon dioxide
Na2CO3(s) + heat -----> Na2O(s) + CO2(g) [not decomposed in normal conditions as Na2CO3 is very stable]
MgCO3(s) + heat -----> MgO(s) + CO2(g)
CoCO3(s) + heat -----> CoO(s) + CO2(g)
CuCO3(s) + heat -----> CuO(s) + CO2(g)
these are some examples from which you can get help.
When marble is heated, it undergoes a chemical reaction called thermal decomposition. This reaction breaks down the calcium carbonate (CaCO3) in marble into calcium oxide (CaO) and carbon dioxide (CO2) gas.
Calcium bicarbonate and calcium carbonate.
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
Tricalcium citrate and water
sodium carbonate + copper sulfate ===> copper carbonate (s) + sodium sulfateNa2CO3(aq) + CuSO4(aq) ===> CuCO3(s) + Na2SO4(aq)
Thermal decomposition of calcium carbonate release calcium oxide (CaO).
If you're talking about thermal decomposition then the answer is Calcium Oxide (s)
Yes, it is a chemical change; new compounds (elements) are formed !
When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
When marble is heated, it undergoes a chemical reaction called thermal decomposition. This reaction breaks down the calcium carbonate (CaCO3) in marble into calcium oxide (CaO) and carbon dioxide (CO2) gas.
The precipitate formed from the reaction between silver nitrate and potassium carbonate is silver carbonate (Ag2CO3), which is a white solid.
If you're talking about thermal decomposition then the answer is Calcium Oxide (s)
Magnesium oxide is formed, i think(:
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
The precipitate formed when magnesium nitrate and sodium carbonate are mixed is magnesium carbonate. This is because sodium nitrate is soluble in water, leaving magnesium carbonate as the insoluble compound that precipitates out of the solution.
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.
Sodium carbonate is formed from the reaction of the sodium ion with the carbonate ion in the form of Na2CO3. It is an ionic compound that consists of sodium cations (Na+) and carbonate anions (CO3^2-).
