Indigo is the dye used in coloring blue jeans. The term navy blue is derived from the use of indigo to dye British naval uniforms in the eighteenth century. The structure of the indigo molecule is

b. What hybrid orbitals are used by the carbon atoms in the indigo molecule?

Draw the Lewis structures for TeCl ₄, ICl₅, PCl₅, KrCl₄, and XeCl₂. 

Which of the compounds exhibit at least one bond angle that is approximately 120 degrees? 

Which of the compounds exhibit d ²sp³ hybridization? 

Which of the compounds have a square planar molecular structure? 

Which of the compounds are polar?

Write Lewis structures for CO₃^2-, HCO₃^-, and H₂CO₃. When acid is added to an aqueous solution containing carbonate or bicarbonate ions, carbon dioxide gas is formed. We generally say that carbonic acid (H₂CO₃) is unstable. Use bond energies to estimate ΔE for the reaction (in the gas phase) 

H₂CO₃ → CO₂ + H₂O 

The reaction

I ^- (aq) + OCl ^- (aq) → IO ^- (aq) + Cl ^- (aq)

was studied, and the following data were obtained:

c. Calculate the initial rate for an experiment where both I  ^- and OCl ^- are initially present at 0.15 mol/L.

Sulfuryl chloride (SO₂Cl₂) decomposes to sulfur dioxide (SO₂) and chlorine (Cl₂) by reaction in the gas phase. The following pressure data were obtained when a sample containing 5.00 x 10^-2 mol sulfuryl chloride was heated to 600. K in a 5.00 x 10 ^-1-L container.

Defining the rate as - Δ [SO₂Cl₂] / Δt,
a. determine the value of the rate constant for the decomposition of sulfuryl chloride at 600. K.
