Lewis structure of this molecule (or molecular ions)?How many lone-pairs of electrons are on the Ocentral atom?How many (σ) sigma bonds does this molecule have?How many (π) pi bonds does this molecule have?Does this molecule have resonance structures?YesNo
. a) Draw the Lewis structure of SO3 2- . b)- Identify the
electronic and molecular geometries of the molecule, and the
hybridization of the central atom. c) Is this molecule polar?
Justify your answer by drawing the VSEPR molecular geometry and
labeling the molecular dipole moment.

Depletion of the ozone layer is believed to be caused by chlorine
catalyzed O3 decomposition. For the uncatalyzed reaction Ea,f= 19
kJ/mol. For the following mechanism, Ea1, f =2.1 and Ea2,f =0.4
kJ/mol:
Proposed Mechanism:
Cl+O3--> ClO +O2
ClO+O--> Cl+O2
a.) What is the dH for the reaction?
I know the answer is -390 kJ/mol. I don't know where this answer
comes from!
b.) What is the Ea, r for the uncatalyzed reaction?
I know the...
