(a)[4]
Using the kinetic particle model, describe the arrangement and motion of the molecules in: • liquid bromine • bromine gas
(b)[1]
Describe the change in the volume of the bromine gas as temperature changes.
(c(i))[2]
Complete the word equation to show which halogen and halide compound react to produce bromine and potassium chloride. [BLANK] + [BLANK] → bromine + potassium chloride
(c(ii))[1]
Explain, using halogen reactivity, why aqueous bromine does not react with aqueous potassium chloride.
(d(i))[2]
Complete the chemical equation for this reaction. [BLANK] + $\text{H}_2\text{S}$ → [BLANK]$\text{HBr}$ + $\text{S}$
(d(ii))[1]
Explain how the diagram indicates that the reaction is exothermic.
(e)[2]
Describe a test used to identify bromide ions. test observations
