Answer:

The amount of N2O4 increases.

Explanation:

Based on LeCh's principle, a change in the state of an equilibrium produce an effect in the system that try to restore the initial equilibrium.

For example, in the problem, the change is the increasing in the pressure. The system will try to decrease the pressure of the system. To decrease the pressure the system needs to decrease the moles of gas. As 2 moles of NO2 produce 1 mole of N2O4, the system will:

Shift to the right increasing the amount of N2O4 and decreasing the amount of NO2. Right option is:

<h3>The amount of N2O4 increases. </h3>

Ionic compounds generally have lower boiling and melting points than covalent compounds.

Anuta_ua [19.1K]

Answer:

The given statement is false.

Explanation:

Ionic bond is formed by strong electrostatic attraction between two atoms having large difference in their electronegativity.This strong electrostatic attraction provide structural stability to the ionic compounds.For example NaCl.

The ionic compounds generally are solid in nature.As a result their melting point and boiling point are higher that covalent compounds as covalent compounds exist in liquid of gaseous state.
