Answer: This chemical reaction is defined as synthesis reaction.
Explanation:
Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to produce a single compound.
The general chemical equation representing this reaction is:
[tex]A+B\rightarrow AB[/tex]
For the given chemical reaction:
[tex]2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)[/tex]
Hence, this chemical reaction is defined as synthesis reaction.
