CaCO3(s) CaO + CO2 is an example of: Select one:a. Decomposition b. Addition c. Combination d. Displacement

Option(A) is correct. Here CaCO₃ is split to form two new compounds. Which is nothing but Decomposition reaction

ADDITIONAL INFO:-

COMBINATION REACTION:-

When two (or) More elements combine to form a new compound is called a Combination reaction.

EXAMPLE :- 2H₂ + O₂ -------> 2H₂O

DISPLACEMENT REACTION :-

The reaction in which the displacement of the element of high reactivity and the element of low reactivity is called displacement reaction
