review the section on Bond Polarity and Partial Ionic Character and the figure that has ionic character on the Y axis and delta EN on the X axis (this is figure 9.24 on page 393 of the 8th edition). Review the graph and Critique the following statement: HF is a covalent molecule and LiI is an ionic compound. Provide as much detail and explanation as possible in 100 word or less. As stated previously, equations, formulas etc. may be substituted for words.

Can u explain this one with an answer thank you

Given the electronegativity for O is 3.5 and S is 2.5 in Sulfate, would you predict the molecule to be polar or nonpolar"

Draw the lewis structure on the left, and fill in the questions on the right. Thank you.

Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.)
