Answer:
If two substances react to form one product , a synthesis reaction has occurred
Explanation:
The reaction in which multiple substances react to form a single product then it is called a synthesis reaction.
The synthesis reaction in general form is given by:
[tex]A+B\rightarrow AB[/tex]
where [tex]A\ and\ B[/tex] maybe any compound or elements and [tex]AB[/tex] is the compound product formed by the reactants.
An example of this form of reaction is:
Formation of water
[tex]2H_2(g)+O_2(g)\rightarrow 2H_2O(g)[/tex]
Here 2 moles of hydrogen reacts with 1 mole of oxygen to give 2 moles of water.
