In this reaction
[the figure shows a scheme of a chemical reaction. the reactants are two molecules, one of which consists of a and b, the other - of c and d. the products are two molecules, one of which consists of a and c, the other - of b and d. the potential energy of molecules ab and cd is higher than the potential energy of molecules ac and bd.]
a. the products have been rearranged to form reactants
b. ac is a reactant
c. cd is a product
d. the products have less potential energy than the reactants
e. entropy has decreased

d. the products have less potential energy than the reactants

Explanation:

AB  +  CD   →   AC   + DB

Reactants  →  Products

AC is a product not a reactant

DC is a reactant not a product

Entropy always increases in products

The products have not been rearranged to form reactants

earthquakes in florida are rare because the state is not located near any tectonic plates. in fact, florida is tied for first place as having the fewest earthquakes of any state. much of florida is limestone and seafloor materials that is not conducive to earthquakes.

explanation:

c should be the answer
