(a(ii))[1]
Explain why metallic elements such as gallium conduct electricity well.
(b)[2]
Give the formulae for gallium(III) chloride and gallium(III) sulfate.
(c(i))[2]

(c(ii))[2]
Write the chemical equation of this reaction.
(d)[2]
Alloys made from gallium and other elements are often more useful than the metallic element alone. Suggest two reasons why alloys of gallium are more useful than the metallic element.
