Need asap analyze the shape of h2o. what is the shape of the h2o molecule? is it symmetrical? does this mean that the h2o molecule is polar or nonpolar?

The answers are in the explanation.

Explanation:

Analyze the form of H2O: The water molecule is composed of an oxygen atom, linked to two hydrogen atoms. The oxygen atom shares one pair of electrons with each hydrogen atom, leaving two pairs of free electrons in the oxygen without sharing.

What is the shape of the H2O molecule? The pairs of unshared electrons exert a repulsion, so the molecule acquires the angular shape.

Is it symmetrical? The H2O molecule is asymmetric due to free electron pairs.

Does this mean that the H2O molecule is polar or non-polar? Does this mean that the molecule is polar, as the uneven distribution of electrons gives it a slightly negative charge near the oxygen atom and a slightly positive charge near the hydrogen atoms.

Have a nice day!

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.
