Cations from smallest to largest
Li⁺ ,Na⁺, K⁺ (from Periodic Table, the bigger number of period, the bigger size, of atom, so the bigger size of cation)
1) LiF smaller cation then KF
1,036 <span>853
</span><span>The lattice energy increases as cations get smaller, as shown by LiF and KF.
</span><span>I think this one should be correct answer, because the compared substances have also the same anion, and we can compare cations in them.
2) The same cation Li , so wrong statement.
3)</span>The same cation Na , so wrong statement.
4) NaCl smaller cation then KF

freezing and condensation
Explanation:
The motion of the atoms decreases during freezing and condensation. These are phase changes that increases the molecular attraction between particles and forces them to come closer.
Freezing is a phase change from liquid to solid. It is usually achieved by removing heat from a substance and cooling it.
Condensation is a phase change from gases to liquid. .
Gases have the greatest motion because they have little to no attractive forces between them.
Phase changes from gas to solid to liquid generally reduces the motion of the atoms.

Answer:
d = 11400 kg/m³
Explanation:
The density of lead is 11.4 g/cm³
We need to convert the density in kg/m³ in scientific notation.
We know that,
1 kg = 1000 g
1 cm = (1/100) m = 0.01 m
Density,
![d=11.4\ \dfrac{g}{cm^3}\\\\=11.4\times \dfrac{(\dfrac{1}{1000})\ kg}{(0.01\ m)^3}\\\\=11400\ kg/m^3](https://tex.z-dn.net/?f=d%3D11.4%5C%20%5Cdfrac%7Bg%7D%7Bcm%5E3%7D%5C%5C%5C%5C%3D11.4%5Ctimes%20%5Cdfrac%7B%28%5Cdfrac%7B1%7D%7B1000%7D%29%5C%20kg%7D%7B%280.01%5C%20m%29%5E3%7D%5C%5C%5C%5C%3D11400%5C%20kg%2Fm%5E3)
So, the density of the lead is 11400 kg/m³.
