Apiece of chromatography paper is spotted with a solution containing iron chloride and nickel chloride. suppose that the chemical affinity of fe3+ for the stationary phase is less than that of ni2+, while the chemical affinity of fe3+ for the mobile phase is greater than that of ni2+. which cation will travel farther at the completion of the chromatography experiment? which cation will have the larger r value?

answer; /// i do believe that the correct answer is (a) boiling

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.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
