The information below relates to elements S,T,U and X. (the letters do not represent the actual symbols of the elements).
(i) T displaces X from aqueous solution containing ions of X.
(ii) Hydrogen gas reduces heated oxide of S but does not reduce the heated oxide of X.
(iii) U liberates hydrogen gas from cold water but T does not. (a) Write an equation for the reaction between T and the ions of X (both T and X are in group II of the periodic table)
(b) Arrange the elements in order of their increasing reactivity.
