Answer:

The answer to your question is because of surface tension

Explanation:

Surface tension is defined as the property of the surface of a liquid that allows  it to resists an external force.

From the definition, we conclude that the molecules at the surface of water are extremely close and do not allow certain bugs to penetrate it so they can walk through it.

While the molecules at the surface of octane are not as close as those molecules in water so a bug sinks on it.

In conclusion, the surface tension of water is higher than the surface tension in octane.

The lattice energy of a salt is related to the energy required to separate the ions. For which of the following pairs of ions is
Kay [80]

Answer: The Lattice energy is the energy required to separate an ionic solid into its component gaseous ions <em>or</em>

It is the energy released when gaseous ions combine to form an ionic solid.

Explanation:

The lattice energy depends on the ionization energies and electron affinities of atoms involved in the formation of the compound. The ionization energies and electron affinities also depends on the ionic radius and charges of the ions involved. As the ionic radius for cations <em>increases</em> down the groups, ionization energy <em>decreases</em>, whereas, as ionic radii <em>decreases</em> across the periods , ionization energy <em>increases</em>. The trend observed for anions is that as ionic radii <em>increase </em>down the groups, electron affinity <em>decreases. </em>Across the period, as ionic radii <em>increases</em> electron affinity <em>increases</em>. Also, as the charge on the ion <em>increases,</em> it leads to an <em>increase</em> in energy requirement/content.

Therefore, for compounds formed from cations  and anions in the same period, the highest charged cation and anion will have the highest lattice energy. For example, among the following compounds: Al2O3 (aluminium oxide), AlCl3 (aluminium chloride), MgO, MgCl2 (magnesium chloride), NaCl, Na2O (sodium oxide); Al2O3(aluminium oxide) will have the highest lattice energy, thus will be hardest to break apart because its ions have the highest charge.
