5 This question is about ionic bonding. (a) The elements sodium and fluorine react together to form an ionic compound. (1) Select the correct equation for this reaction. (1) A Na(s) + F(g) → NaF(s) B2Na(s) + F2(g) → 2NaF(s) BC Na(s) + F(g) - NaF_(s) OD 2Na(s) + F(g) Na F(s) (11) Draw dot-and-cross diagrams of the ions in sodium fluoride, showing all the electrons. Use your diagram to explain why the ions are described as isoelectronic. (3)

6 This question is about the molar volume of gases. (a) (0) Calculate the volume of one mole of an ideal gas, A, at 60 °C and 500 kPa pressure. Give your answer to two significant figures and include units. [The ideal gas equation is pV = nRT. Gas constant (R) = 8.31JK 'mol-'] 4
