Determine the molar mass of the Empirical formula C2H6O(Carbon to the 2nd, Hydrogen to the 6th, and Oxygen). Then solve for the molecular formula.

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

a patient chooses to not take a beneficial medical treatment.

explanation:

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.

i think   the answer is c hope i'm right
