See the explanation.

Explanation:

Synthesis reactions occur when two or more simpler substances (atoms, ions, molecules) react to produce a single product.

Hydrogen peroxide is synthesized by the reaction between water and oxygen.

#"2H"_2"O" + "O"_2"##rarr##"2H"_2"O"_2"#

Decomposition reactions occur when a single compound is broken down into simpler products.

Potassium chlorate decomposes to produce potassium chloride and oxygen.

#"KClO"_3"##rarr##"KCl + O"_2"#
