2 marksReactivity and Extraction of Metals

CSEC Chemistry · January 2009 · Paper 2 · Question 3(a)

Table 4 lists properties of four metals (A, B, D, E) and their compounds. The metals do not need to be identified.

Arrange Metals A, B, D and E in order of reactivity with the MOST reactive FIRST.

This question uses a figure or table from the paper — you'll see it when you practise.
