Not really a chemistry question BUT its for my class if you could change a CLASSROOM (not school) rules what rule would you change?

(can someone please help me out i can't think of classroom rules I would change)

Schools should abolish healthy food policies (rules that you are only allowed bring in healthy food for break/lunch). Our school is too small to fit a cafeteria so we need to bring a packed lunch to school.

answer: mercury

explanation:

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.
