In this reaction a bar chart of potential energy of molecules for reactants and products. the reactants are a b and c d, and the products are a c and b d. potential energy of reactants is much higher than that of products. in this reaction a bar chart of potential energy of molecules for reactants and products. the reactants are a b and c d, and the products are a c and b d. potential energy of reactants is much higher than that of products. entropy has decreased cd is a product the products have less potential energy than the reactants the products have been rearranged to form reactants ac is a reactant

The products have less potential energy than the reactants

Explanation:

Potential Energy is energy that can be stored in a physical system and has the ability to be transformed into kinetic energy. Potential energy is the name given to the form of energy when it is 'stored', ie it can at any time manifest itself as chemical reactions, where energy is released as a result of the work done by the reaction. . Thus, the reaction product will have less potential energy than the reactants, an example of this is the reaction described in the question above.

 The given statement is true.

Explanation: The Challenger expedition was a scientific tour that made the discoveries of many marine life. This laid the foundation related to the  oceanography. The whole tour( expedition) was named after the Mother vessel the HMS Challenger, who was leading the expedition.

She travelled more than 70,000 nautical miles in exploring and surveying the marine life which led to the discovery of more than 4000 new species of the marine life.
