One of the goals of this experiment is to show the molar ratio of Mg / O is 1. Almost all students when conducting this experiment will determine this to be greater than 1. Will the following error lead to a Mg / O molar ratio greater than 1 or less than 1? Error: The reaction was not heated long enough, and as a consequence not all of the magnesium reacted.

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.
