6. A Lewis symbol for an atom with a configuration of 1s² 2s²2p6 3s² 3p64s² 3d¹⁰4p5 would show (a) 1 unpaired electron and 3 electron pairs (b) 2 unpaired electron and 2 electron pairs (c) 1 unpaired electron and 2 electron pairs (d) 3 unpaired electrons and 1 electron pair (e) 3 unpaired electrons and 2 electron pairs 7. The values of A-H°(25 °C) for SO₂(g) and SO3(g) are -296.8 and -395.7 kJ /mol. What is the value of A,H°(25 °C) per mole of SO₂ for the following reaction? 2SO2(g) + O2(g) → 2SO3(g) (a) 692.5 kJ/mol (b) 692.5 kJ/mol (c) 98.9 kJ/mol (d) -98.9 kJ/mol
