In this reaction a scheme of a chemical reaction. the reactants are two molecules, one of which consists of a and b, and the other consists of c and d. the products are two molecules, one of which consists of a and c, and the other consists of b and d. the energy of molecules ab and cd is higher than the energy of molecules ac and bd.

The chemical reaction is: AB + CD ---> AC + BD  (ΔH=  - )

Explanation:

After the reaction between two reactants, two products are generated.

As the products have less energy than the reactants, this energy is released and ΔH is negative

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
