Answer:
This question is incomplete but the completed question is below
Adam is trying to identify a solid. He places a small amount of the substance in an acid solution and observes whether or not a reaction takes place. This test is based on a _______ property. A.physical B.chemical C.radical D.biological
The correct option is B
Explanation:
It is a chemical property because a reaction is been used to determine the solid. A reaction is a chemical process that involves the combination/rearrangement of atoms in different substances called reactants (in this case the solid and the acid are the reactants) to give new substances called products.
It is not a radical property because radicals are unstable substances that possess unpaired valence electrons. Radical on its own is a function of a chemical property. While biological property will involve a living organism but that was not mentioned. Physical property has to do with the appearance (in any way) of the solid but that was not used.
