#1: which of the following statements is true? a. in an endothermic reaction, the energy of the products is the same as the energy of the reactants. b. in an endothermic reaction, the energy of the products is less than the energy of the reactants. c. in an exothermic reaction, the energy of the products is the same as the energy of the reactants. d. in an exothermic reaction, the energy of the products is less than the energy of the reactants. ***my answer; d is that right? @aaronq : )

Option (D) is the correct answer.

Explanation:

In an endothermic reaction energy is absorbed by reactant molecules in a chemical reaction as a result energy of products is more than the energy of reactants.  

Whereas in an exothermic reaction energy is released by a chemical reaction as a result energy of reactants is more than the energy of products.  

Therefore, we can conclude that the correct statement is in an exothermic reaction, the energy of the products is less than the energy of the reactants.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
