    1. Draw the Lewis structure of the conjugate base for the following acid: H2SO4. Remember to include charges and non-bonding electrons where necessary. Use an expanded octet on sulfur to minimize formal charges.

    2. Draw the conjugate acid for the following base. ::Cl::- Remember to include charges and non-bonding electrons where necessary.

    3. Determine the dissociation constants for the following acids. Express the answers in proper scientific notation where appropriate.

    Acid PKa KA
    A 3.0
    B 8.10
    C -1.0
    Which is the strongest acid?

    4. Rank the given compounds based on their relative acidities.
    HF, H2C=CH2, NH3, H3CCH3, HC-=CCH3.

    1- Draw the Lewis structure of the conjugate base for the following acid.H2SO4 Remember to include charges and non-bonding electrons where necessary. Use an expanded octet on sulfur to minimize formal charges.

    The conjugate base of H2SO4 is HSO4- (bisulfate). Lewis structure is as follows:

    2- Draw the conjugate acid for the following base. ::Cl::- Remember to include charges and non-bonding electrons where necessary.

    The conjugate acid of Cl- is HCl. Lewis structure is as follows:
