A voltaic cell is constructed in which the anode is a Fe2+|Fe3+ half cell and the cathode is a Br-|Br2 half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.)
The anode reaction is:
(aq)(s)(l)(g) + (aq)(s)(l)(g) > (aq)(s)(l)(g) + (aq)(s)(l)(g)
The cathode reaction is:
(aq)(s)(l)(g) + (aq)(s)(l)(g) > (aq)(s)(l)(g) + (aq)(s)(l)(g)
The net cell reaction is:
(aq)(s)(l)(g) + (aq)(s)(l)(g) > (aq)(s)(l)(g) + (aq)(s)(l)(g)
In the external circuit, electrons migrate (from/to) the Fe2+|Fe3+ electrode (from/to) the Br-|Br2 electrode.
In the salt bridge, anions migrate (from/to) the Br-|Br2 compartment (from/to) the Fe2+|Fe3+ compartment.

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.
