A Period 3 oxide forms a solution with a pH above $10$ when water is added. State the formula of the oxide.
With $\text{P}_4\text{O}_{10}$ added to excess aqueous $\text{NaOH}$, write an equation for the reaction.
From Table 2.1, identify the oxide that contains the element with the largest oxidation number.
A student makes this hypothesis: "The melting point of an ionically bonded oxide is only determined by the charge on the cation." Use Table 2.1 to decide whether this hypothesis is true, false, or whether there is insufficient information to reach a conclusion. Explain your answer.
State why $\text{ZnO}$ is described as a Brønsted-Lowry base when added to $\text{H}_2\text{SO}_4\text{(aq)}$.
$\text{Al}_2\text{O}_3$ is a white amphoteric compound. State the formula of the aluminium-containing species formed when $\text{Al}_2\text{O}_3$ reacts with $\text{NaOH(aq)}$.
State the formula of the aluminium-containing salt formed when $\text{Al}_2\text{O}_3$ reacts with $\text{H}_2\text{SO}_4\text{(aq)}$.
$\text{Al}_2\text{O}_3$ is a compound that is white and amphoteric.
