Use the data from this table of thermodynamic properties to calculate the values of δs°rxn for each of the following reactions at 25 °c. a) 4nh3(g) + 7o2(g) > 4no2(g) + 6h2o(g) delta s rxn =? b) 2h2o2(l) --> 2h2o(l) +o2 (g) delta s rxn =?

how to make a simple air condition

the answer is either b or c

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.
