PLEASE HELP ANSWER NEEDED FOR FINAL 2Na(s) + 2H20(I) -> +2NaOH(aq)+H2(g) Question #1
How many moles of sodium hydroxide (NaOH) would be produced from the reaction of 225 moles
of sodium (Na) with excess (H20)?
Given unit:
Answer unit:
Solution:

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.
