  1. Na + Br2 → NaBr
  2. KClO3 → KCl + O2
  3. HgO + Cl2 → HgCl + O2
  4. Cl2 + NaBr → NaCl + Br2

hintHint:

A synthesis reaction is a type of reaction in which multiple reactants combine and synthezise a single, complex product. 

The correct answer is: Na + Br2 → NaBr


    Na + Br2 rightwards arrowNaBr is an example of synthesis.
    • It is a synthesis reaction that is the synthesis of sodium bromide from sodium and bromine. 
    • A synthesis reaction is simple to identify in this form since there are more reactants than products.
    • One bigger compound is created when two or more reactants come together.
