What chemical change will occur when a more reactive substance replaces a less reactive substance in a compound? a. oxidative b. reduction c. displacement d. endothermic

The correct answer for above statement is:

C. Displacement.

Explanation:

Displacement reaction is a chemical reaction in which a bounteous reactive element replaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example: Reaction of iron nails with copper sulfate solution.a type of chemical reaction wherever an element counters with a compound and takes the position of another element in that compound.

it's c. elements are placed in rows based on how may valencies electrons have.
