Answer :
thermal decomposition is the decomposition of something being heated up , combustion is basicly burning , were methane and oxygen combined and form carbon dioxide and water
Answer: Thermal decomposition refers to the formation of two or more products from a single reactant while combustion refers to reaction of a substance with oxygen to produce heat, light and other chemical substances.
Explanation:
An example of thermal decomposition is the formation of quick lime (calcium oxide)
CaCO3(s)---------> CaO(s) + CO2 (g)
heat
The two products were formed from a single reactant CaCO3
Combustion refers to the combination of a substance with oxygen, e.g, the combination of coke with oxygen:
C(s) + O2(g) -----------> CO2(g)
Heat and light often accompany combustion reaction.
