Answer: Decomposition
Explanation:
Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.
Polymerization is a reaction where small units called as monomers joine together to form a large molecule called as polymer.
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.
Oxidation is a reaction where a substance loses electrons and undergo an increase in oxidation state.
Replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
