In a neutral compound, the sum of the oxidation states is zero. note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered. in h2o, for example, each hydrogen atom has an oxidation state of 1 and each oxygen atom has an oxidation state of −2 for a total of 2( 1) (−2)

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
