You have made use of the Le Chatelier principle in this lab. Explain how the Le Chatelierprinciple is used to help formation of the product in the reaction you performed in this lab, AND, WHY it isnecessary to make use of the Le Chatelier principle to help this reaction to "go".

CHALLENGE ACCEPTED!

Explanation:

Basically, Le Chatelier's principle is the equilibrium law used to predict the effect of a change in conditions on some chemical equilibra. It is often used to increase the yield of reactions.

i believe the answer is a.

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.
