4. Draw the Lewis structure for sulfur trioxide (SO_(3)) What is the hybridizatior of the sulfur molecule geometry? 5. Give the IUPAC name and the hybridization of the metal ion for following complex: [Cr(H_(2)O)_(4)Cl_(2)]Cl 6. Balance the following equations Cu+HNO_(3)=Cu(NO_(3))_(2)+NO+H_(2)O b) HCl+KMnO_(4)=KCl+MnCl_(2)+H_(2)O+Cl_(2) KClO_(3)+HCl=KCl+H_(2)O+Cl_(2)

4. The Lewis structure for sulfur trioxide (SO3) can be drawn as follows:<br /><br />S = O<br />|<br />O<br /><br />The sulfur atom is bonded to three oxygen atoms, with one double bond and two single bonds. The hybridization of the sulfur atom is sp3.<br /><br />The molecule geometry of SO3 is trigonal planar.<br /><br />5. The IUPAC name of the complex [Cr(H2O)4Cl2]Cl is Chromium(III) chloride dihydrate.<br /><br />The hybridization of the metal ion in this complex is sp3d.<br /><br />6. The balanced equations are:<br /><br />a) 3Cu + 8HNO3 → 3Cu(NO3)2 + 2NO + 4H2O<br /><br />b) 16HCl + 2KMnO4 → 2KCl + 2MnCl2 + 8H2O + 5Cl2<br /><br />c) 2KClO3 + 4HCl → 2KCl + 3H2O + 3Cl2
