Explanation:
Electrostatic force of attraction is the attraction between different molecules that comes from them being electrically charged.
For molecules to have an electrostatic force of attraction, they need to have opposing charges because like charges repel each other but opposite charges attract.
In the question above, the only option that has opposing charges is option D so this is the correct option.
In comparison with liquids and gases, solids are more dense. The answer is letter B. <span>The
solid has a more definite shape and volume. The particles are locked into
place. It cannot be further compressed due to the bond that exists between the
molecules. The kinetic energy of the molecules is close to none because the
molecules are so close and so compact with each other. </span>
"Hydrochloric acid (HCl) is an example of an acid. When it dissolves in water, it produces positive hydrogen ions and negative chloride ions (Cl-). This can be represented by the chemical equation: HCl H2O→ H+ + Cl."
