CaCO3(s) -> CaO(s) + CO2(g)
limestone + lemon lol
The balanced symbol equation for the thermal decomposition of copper carbonate is: CuCO3(s) -> CuO(s) + CO2(g)
The symbol equation for the thermal decomposition of calcium carbonate is: CaCO3(s) -> CaO(s) + CO2(g)
This reaction is correctly named as 'Thermal Decomposition'. CaCO3(s) ==heat==> CaO(s) + CO2(g) The reaction is heated to 'red' heat.
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
the anwer is , 2NaHCO3 --> Na2CO3 + CO2 + H20:)
Thewords are 'Calcium Carbonate' . Otherwise known as limestone, chalk or marble. Its formula is CaCO3 Thart is 1 atom of calcium (Ca) 1 atom of carbon (C) 3 atoms of oxygen (O) It undergoes 'thermal decomposition' at 'red' heat , to form lime and carbon dioxide. CaCO3(s) ==Heat==> CaO(s) + CO2(g).
CaCO3(s) --> CaO(s) +CO2(g) enthalpy is +178 kJ molˉ¹
N(h)4hc(o)3 = nh3 + h2o + co2
Iron is an element and does not decompose. However, it can melt so Fes + HEAT = Fel
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
2 C7H5N3O6 → 3 N2 + 5 H2O + 7 CO + 7 C it is considered a decomposition reaction http://en.wikipedia.org/wiki/Trinitrotoluene
