carbon dioxide from calcium
carbonate is an example of
(a)photochemical decomposition reaction
(b) thermal decomposition reaction
(c) oxidation reaction
(d) displacement reaction​

Answer 1

Answer:

answer is option b ok bro

Answer 2

(b) thermal decomposition reaction is correct example.

• Thermal decomposition is the breakdown of compounds into new compounds made of constituent elements, through heat.
• The thermal decomposition reaction of calcium carbonate is as follows - CaCO3 --> CaO + CO2.
• In this chemical reaction, CaCO3 is the chemical formula of calcium carbonate, CaO is the chemical formula of calcium oxide and CO2 is the chemical formula of carbon dioxide.
