Given the following equation and bond energies, determine which statement is true. n2 + o2 → 2no n-n triple bond: 941 kj/mol o-o double bond: 495 kj/mol n-o bond: 201 kj/mol
a. a nitrogen-oxygen bond is broken.
b. the reaction is exothermic.
c. the products have more energy than the reactants.
d. a triple bond between nitrogen atoms is formed.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
