Answer:

Water breaking down into hydrogen and oxygen is a decomposition reaction

Hydrogen and oxygen combining to form water is a synthesis reaction

Explanation:

A decomposition reaction is a chemical reaction that involves the breakdown of a chemical reactant entity into two or more simpler product fragments

Water Hâ‚‚O undergoes a decomposition reaction by breaking down into hydrogen, Hâ‚‚,, and oxygen, Oâ‚‚, as follows;

2H₂O (l) → 2H₂ (g) + O₂ (g)

A synthesis reaction is a reaction that involves the chemical combination of two or more dissimilar molecules or atoms to produce a different compound or molecule

Water, Hâ‚‚O, is formed by a synthesis reaction of hydrogen, Hâ‚‚,, and oxygen, Oâ‚‚, combining as follows;

2H₂ + O₂  → 2H₂O
