Thermal decomposition refers to the process of a substance decomposing as a result of being exposed to heat. The heat typically breaks the chemical bonds in the substance, which leads to the decomposition.
It is the break down of a compound by heat; heat is required to break chemical bonds in the compound and so the term 'thermal.'
-H2CO3 → H2O + CO2
Carbonic acid → Water + Carbon dioxide
(Heat applied)
-CaCO3→CaO + CO2
(Heat applied)
Calcium carbonate → Calcium oxide + Carbon dioxide
the reaction in which a single compound breaks down to give two or more simpler substances are called decomposition reaction.
there are three types of decomposition reactions
1.thermal decomposition
2.electrolytic decomposition
3.photolytic decomposition
examples:-
CaCO3 (arrow) CaO + O2
2NaCl (arrow) 2Na + Cl2
2AgCl (arrow) 2Ag + Cl2
If in a reaction 2 or more than 2 substances are obtain by decomposition of 1 substance by heating, then the reaction is called thermal decomposition reaction
For eg. CaCo3 give rise to CaO + CO2 (in this reaction lime stione is heated, calcium oxide & carbon dioxide r obtained due to decomposition reaction. Hence it is an eg. of thermal decomposition reaction.)
it is the spliting of something by heat its carbonate element
During thermal decomposition, compounds absorb energy and are broken apart.
Zinc nitrate decomposes on heating to give zinc oxide, nitrogen dioxide and oxygen:
Zn(NO3)2 (s) -----> 2ZnO (s) + 4NO2 (g) + O2 (g)
During thermal decomposition a big molecule is transformed in smaller molecules
it is used to measure a straight line
Thermal decomposition
Thermal decomposition is the process by which chemical bonds are broken in the presence of heat. Decomposition temperature is the temperature at which thermal decomposition occurs, which differs for different compounds.
Solids melt on heating. A2. But if you are thinking of the destruction of the material, perhaps pyrolysis is what you seek.
A method is the thermal decomposition of a compound.

A method is the thermal decomposition of a compound.
This is a thermal decomposition reaction: new compounds are obtained by heating.
The thermal decomposition has the following equation: CaCO3 --------CaO + CO2
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
