Amanda paired with janice while deja paired with eden for a chemistry project. for the earth science project, amanda paired with eden while deja paired with janice. which type of chemical reaction does the situation demonstrate?

The situation demonstrates and double displacement chemical reaction.

Explanation:

Here is a double displacement reaction:  

AB + CD = AC + BD

A combines with B and C combines D in the reactant. In the formation of the product A swaps partner and combines with C and B swaps partner and combines with D.  

For example, silver nitrate combines with sodium chloride to form silver chloride and sodium nitrate.

AgNO₃ + NaCl → AgCl + NaNO₃

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
