Question
On the basis of the compositions and physical states of Earth's various layers (Figure 3.3 ), which of the following substances has the higher melting point: $\mathrm{Al}_{2} \mathrm{O}_{3}$ or $\mathrm{Ni}$ ?
Step 1
$\mathrm{Al}_{2} \mathrm{O}_{3}$ is a molecule, which means it has intermolecular bonds. On the other hand, $\mathrm{Ni}$ is an element, which means it does not have any bonds to break. Show more…

On the basis of the distribution of the elements in Earth's layers (see Figure $3.3),$ which of the following substances should be the most dense? (a) $\mathrm{SiO}_{2}(s) ;$ (b) $\mathrm{Al}_{2} \mathrm{O}_{3}(s) ;$ (c) $\mathrm{Fe}(\ell)$.
Which metal do you expect to have the higher melting point- Al or Na? Explain your answer.
For each pair of solids, determine which solid has the higher melting point and explain why. (a) $\operatorname{Fe}(s)$ and $\mathrm{CCl}_{4}(s)$ (b) $\mathrm{KCl}(s)$ or $\mathrm{HCl}(s)$ (c) $\mathrm{TiO}_{2}(\mathrm{s})$ or $\mathrm{HOOH}(s)$
