Use the data given below to construct a born-haber cycle to determine the heat of formation of kcl. δ h°(kj) k(s) → k(g) 89 k(g) → k+(g) + e- 418 cl2(g) → 2 cl(g) 244 cl(g) + e- → cl-(g) -349 kcl(s) → k+(g) + cl-(g) 717 use the data given below to construct a born-haber cycle to determine the heat of formation of kcl. h°(kj) k(s) → k(g) 89 k(g) → k+(g) + e- 418 cl2(g) → 2 cl(g) 244 cl(g) + e- → cl-(g) -349 kcl(s) → k+(g) + cl-(g) 717 -1119 kj +631 kj +158 kj -997 kj -437 kj

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 option a.
