12. How many molecules of ammonia are produced from the reaction of 9.5 * 1023 molecules of nitrogen are reacted with excess hydrogen gas? N2 + 3H2 → 2NH3
O 2.9 10% molecules NH3
O 1.9 * 1024 molecules NH3
O 2 molecules NH3
O 9.5 * 1023 molecules NH3

Sorry my account got hacked for 900 points and I'm trying to get them back  have a good day tho

Explanation:

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.
