<h3>
Explanation:</h3>
- Synthesis reactions are reactions where two or more substances combine to form a single compound.
- The reaction 2NO(g) + O₂(g) → 2NO₂(g) is an example of a synthesis reaction.
Other types of chemical reactions may include;
- Decomposition reaction in which a compound is broken down into smaller compounds or individual elements.
- Replacement reaction where reactive elements replace other less reactive elements in their salts.
- Precipitation reactions in which soluble salts reacts to form a precipitate and a soluble salt as a result of exchange of anions and cations.
