Barney is in a hurry to get home and watch the television show he recorded, in his haste; he deviates from the experimental procedure in several ways. explain how these would affect the outcome of the end result, number of milligrams of iron in the tablets. would these sway the result erroneously higher, lower, or make no change? while dissolving the kmno4 crystals, he does not allow enough time for all of it to dissolve leaving some behind. what will this do to the number of milligrams of iron tablets? the number will be erroneously low. the number will not change. the number will be erroneously high

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.
