Calculate, use hess’s law to determine /\H for the reaction NO(g) + O(g)—> NO2(g) /\H=? given the following reactions. show your work O2(g)—>2O(g)/\H= + 495 kJ
2O3(g)—>3O2(g)/\H = -427 kJ
NO(g) + O3(g)—> NO2(g) + O2(g) /\H= -199 kJ

increased stability in the completion of fluorine's outer shell.

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.
