Answer: This reaction will produce a compound.
Explanation:
Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to produce a single product known as compound.
General chemical equation for this reaction follows:
[tex]A+B\rightarrow AB[/tex]
For Example: Formation of water from hydrogen and oxygen gas.
[tex]2H_2(g)+O_2(g)\rightarrow 2H_2O(l)[/tex]
Hydrogen and oxygen gases are combining to produce a compound known as water molecule.
Thus, this reaction will always produce a compound.
