CaCO3(s) -> CaO(s) + CO2(g)
limestone + lemon lol
CaCO3 (s) -----> CaO (s) + CO2 (g)
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
It is CaCO3, also known as Calcium Carbonate.
the anwer is , 2NaHCO3 --> Na2CO3 + CO2 + H20:)
CuCO3 --> CO2 + CuO (gas + black powder) Further heating may result in : CuO --> 2Cu + O2 (metal copper + gas)
N(h)4hc(o)3 = nh3 + h2o + co2
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
Iron is an element and does not decompose. However, it can melt so Fes + HEAT = Fel
Limestone is predominantly calcium carbonate, CaCO3, and reacts with hydrochloric acid as follows: CaCO3(s) + 2HCl(aq) --> CaCl2(aq) + CO2(g) + H2O
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
CaCO3(s) --> CaO(s) +CO2(g) enthalpy is +178 kJ molˉ¹
