A 5.000 g sample of an unknown insecticide made up of C, O, and Cl is analyzed by combustion analysis. 8.692 g of CO2 and 1.142 g of H2O are recovered. A second 5.000 g sample in another analysis gave 2.571 g of HCl. What is the empirical formula? What is the molecular formula if the unknown’s molar mass is around 354 g/mol.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
