Cyclobutane, c h , consisting of molecules in which 48 four carbon atoms form a ring, decomposes, when heated, to give ethylene. the reaction is first order. in an experiment, the initial con- centration of cyclobutane was 0.00150 m. after heating at 450°c for 455 s, this was reduced to 0.00119 m. what was the concentration of cyclobutane after a total of 875 s?

d.) circle motion requires a force to give it a centripetal acceleration.

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 terrae but not 100 percent sure. ▓▬▬ §
