Propanone and iodine react in aqueous acidic solution according to the following overall equation:
CH, COCH3 + 12 + H - CH3COCH, I + 2H+ +1
The experimentally determined rate equation for this reaction is
rate = k{CH COCH3][H+]

true

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.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
