State what you would observe, and write equations for the reactions, when magnesium chloride, aluminium chloride and silicon tetrachloride are each mixed separately with water.
Calculate the number of moles of chloride ions in $100\text{ g}$ of this meat product.
Write the ionic equation, with state symbols, for the reaction between aqueous sodium chloride and aqueous silver nitrate.
Calculate the volume of $0.0200\text{ mol dm}^{-3}$ silver nitrate solution that would be needed if this titration were performed on $100\text{ g}$ of the particular meat product described above.
Using bond enthalpies from the Data Booklet, calculate the enthalpy change for the reaction $\text{C}_6\text{H}_6 + \text{I}_2 \rightarrow \text{C}_6\text{H}_5\text{I} + \text{HI}$.
Nitric acid reacts with hydrogen iodide according to the unbalanced equation: $\text{HI} + \text{HNO}_3 \rightarrow \text{I}_2 + \text{N}_2\text{O}_3 + \text{H}_2\text{O}$. Balance this equation, and describe how the oxidation numbers of nitrogen and iodine change during the reaction.
