Arrange the species O2+, O2, O2−, O22− in order of increasing bond length.

When drawing the Lewis structure of the HCC13 molecule, the structure should represent a total of 26 valence electrons. What is the best description of the complete Lewis structure of the molecule? Select one: AH atom should be in the center with single bonds to each Cl atom and a double bond to the C atom. A Cl atom should be in the center with a single bond to the C atom and a single bond to the H atom. AC atom should be in the center with a double bond to the H atom and double bonds to each Cl atom. AC atom should be in the center with single bonds to each Cl atom and a single bond to the H atom.

Let Su, Tn, and VI be imaginary elements in the same column in the periodic table. Their relative electronegativities are Su > Tn > VI and their relative atomic radii are VI > Tn > Su. Which of the following anions would have the highest K₁? ⒸHSUO₂ ⒸHVIO₂ ⒸHTnO₂ All of these would be expected to have the same Kb.

How many double bonds are present in Yellow No. 6? (Include the S=O double bonds).

.  The Pauling scale of electronegativity is based upon bond dissociation energies, D,  and involves using the equation  DAB = (DA2 x DB2)1/2 + Δ .  For what process does Δ represent the energy?  How is Δ related to electronegativities?

While sulfur forms the compound SF6, no equivalent compounds of oxygen, OF6, are known. Explain why.

Use average bond enthalpy values to calculate ΔrH for the following reaction: 2NH3 + 3Cl2 → N2 + 6HCl
