Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH-] is
1x10 ^-12 mol/L

1x10^-2mol/L

Explanation:

[OH-] = 1x10 ^-12 mol/L

Recall:

[H+] x [OH-] = 1x10^-14

[H+] x 1x10 ^-12 = 1x10^-14

Divide both side by 1x10 ^-12

[H+] = 1x10^-14/ 1x10 ^-12

[H+] = 0.01 = 1x10^-2mol/L

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.
