In order to have the outer 4 electrons involved in bonding (as in SnI4), it is necessary to promote an s electron to an empty p orbital, and following hybridization these 4 unpaired electrons can form covalent bonds. In order to promote an s electron to an empty p orbital, energy is required. Is it energetically favourable to promote this electron when bonding? Why or why not?
Observe significant figure rules. Constants: ideal gas const = R = 0.08206 L atm/mole K; 1 mole of gas at STP occupies 22.41 L. Atomic masses: H 1.008 O 16.000 g/mole. You must show work to identify the limiting reagent; no credit for guessing.
