Question

Draw the Lewis structure for OF2 and use it to identify the correct statements that follow. Select all that apply. The structure has one lone pair of electrons. The molecular geometry (shape) is linear. ? The molecule is nonpolar. The structure is drawn with 20 valence electrons. The central atom electron geometry is tetrahedral. QUESTION 8 What is the name of the compound that forms when Ca$^{2+}$ bonds with SO$_4^{2-}$? Calcium sulfide Calcium (II) sulfite Calcium sulfate Calcium sulfur tetraoxide Calcium sulfoxygenate QUESTION 9 Which atom or compound is oxidized in the balanced chemical reaction below? 4Al(s) + 3O$_2$(g) $\rightarrow$ 2Al$_2$O$_3$(s) Al O$_2$ Al$_2$O$_3$ Both Al and O$_2$ None of these, this is not an oxidation/reduction reaction
