CSEC Chemistry · January 2010 · Paper 2 · Question 2(a)(i)

V and Q are two different forms of the element carbon. R is an ionic solid. Table 3 presents some properties of V, Q and R.

Complete Table 3 by writing in the table, the structure of V and electrical conductivity of Q.

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