The ph of a cup of black coffee is 5 while the ph of glass of tomato juice is 4. comparing the ph of the two liquids, the tomato juice has [h+] than the coffee. a) half as many b) 10 times more c) 10 times less d) 100 times more

 THE ANSWER IS B!!

Explanation:  Comparing the pH of the two liquids, the tomato juice has 10 times more [H+] than the coffee. Another way to represent the [H+] of the two liquids is: coffee = 1 X 10-5 and tomato juice = 1 X 10-4. You can then see that tomato juice has 10 times more [H+].

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.
