1) Potassium Chloride
Chemical formula

KCl

Explanation:

Potassium chloride is an ionic compound and is a salt with a powdery and crystalline appearance that naturally occurs as a solid. KCl is the chemical formula: it is made up of one ion of potassium (K+) and one ion of chlorine (Cl-).

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

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.
