Which clue can be used to identify a chemical reaction as a combination (synthesis) reaction?
One clue that can be used to identify a chemical reaction as a combination (synthesis) reaction is the presence of only one product. In a combination reaction, two or more reactants combine to form a single product. Therefore, if there is only one product present in the reaction, it is an indication that a combination reaction has occurred.
a
The reaction has a single reactant.
b
The reaction involves heat.
c
The reaction involves ions.
d
The reaction has a single product.
d) The reaction has a single product.
A combination (synthesis) reaction involves the combination of two or more reactants to form a single product. Therefore, if there is only one product present in the reaction, it is an indication that a combination reaction has occurred.
