Which statement describes a chemical reaction?
atoms in the products are rearranged to form new substances.
atoms in the reactants are rearranged to form new substances.
atoms in the products change into new atoms to form new substances.
atoms in the reactants change into new atoms to form new substances.

Atoms in the reactant are rearranged to form new substances.

Explanation:

Atoms in the reactant are rearranged to form new substances.

The Law of the conservation of mass says that in a closed system, the mass of a system must remain the same. So we can say that in a reaction have the reactants A, B and C, the products will have A, B and C.

AB + C --> AC + B

The same amont of all compounds are present in the reactants and on the products.

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.
