Give a chemical equation for the reaction of chlorine with aqueous potassium bromide.
State the colour of the silver chloride precipitate.
Work out the number of moles in $2.87\,\text{g}$ of AgCl.
Using your answer to (b)(ii) and the ionic equation, determine the number of moles of chloride ions, $\text{Cl}^-$, that gave $2.87\,\text{g}$ of AgCl.
Use this together with your answer to (b)(iii) to find the whole-number ratio of moles of vanadium chloride : moles of chloride ions. Then deduce the formula of vanadium chloride.
Predict what physical state astatine has at room temperature and pressure.
Write a chemical equation for the reaction of sodium with astatine.
Calculate the total energy needed to break the bonds in 1 mole of $\text{I}_2$ and 1 mole of $\text{Cl}_2$.
Calculate the total energy released when the bonds in 2 moles of ICl are formed.
Use your answers to (d)(i) and (d)(ii) to work out the overall energy change for the reaction: $\text{I}_2 + \text{Cl}_2 \rightarrow 2\text{ICl}$.
