The student is now told that the four solids, in no particular order, are calcium bromide (cabr2), sugar (c6h12o6), benzoic acid (c6h5cooh), and potassium bromide (kbr). assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 m solution in water will conduct electricity.

list from most conductivity to lease conductivity in order (the ones i am typing out are in a random order):

calcium bromide
sugar
potassium bromide
benzoic acid

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

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.

hope this .
