Fill in the ‘bonding’ row of the table using only the words ‘ionic’ or ‘covalent’.
Fill in the ‘structure’ row using only the words ‘simple’ or ‘giant’.
From the oxides shown in the table above, suggest the formula of one oxide that is completely insoluble in water.
Separate samples of $\text{Na}_2\text{O}$ and $\text{SO}_2$ were each added to water. For each oxide, write a balanced equation for its reaction with water and suggest a numerical pH value for the solution formed.
Write a balanced equation for the reaction that takes place when a solution of $\text{Na}_2\text{O}$ in water reacts with a solution of $\text{SO}_2$ in water.
Separate samples of the oxides $\text{MgO}$ and $\text{SiO}_2$ are melted. Each molten sample is then tested to find out whether it conducts electricity. Suggest the result for each case. Explain your answers.
