Question 10 of 10 What is the hybridization of the carbon in \( \mathrm{CO}_{2} \) and bond order of the \( \mathrm{CO}_{2} \) molecule?

Which of the following molecule(s) have lone pair electrons and/or non-identical central bonds? \( \mathrm{CCl}_{4} \) \( \mathrm{CHCl}_{3} \) \( \mathrm{SO}_{3} \) \( \mathrm{CO}_{2} \mathrm{O} \)

Based on your worksheet results, please match the following: The electron group geometry of NH 3 is The electron group geometry of BF 3 is [Choose ] The electron group geometry of \( \mathrm{PF5} \) is [Choose ] [Choose ] electron group geometry of SF4 is geometry of PF 3 is [Choose ]

Please select polar molecule(s) from the following. \( \square \mathrm{CCl} 4 \) \( \square \mathrm{CHCl} 3 \) \( \square \mathrm{CO} 3 \) CO 2

\[ \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s})+2 \mathrm{Al}(\mathrm{s}) \rightleftharpoons \mathrm{Al}_{2} \mathrm{O}_{3}(\mathrm{~s})+2 \mathrm{Fe}(\mathrm{s}) \] View Available Hint(s) The equilibrium will shift toward the reactants. The equilibrium will shift toward the products. The reaction will not shift toward either the products or reactants. The reaction will shift toward both the reactants and products.

Which of the following represent a buffer system? Check all that apply. \( \square \mathrm{NaOH} \) and NaCl \( \square \mathrm{H}_{2} \mathrm{CO}_{3} \) and \( \mathrm{NaHCO}_{3} \) HF and KF KCl and NaCl
