Q1 Molecule Shapes and Polarity: Consider the fluoromethanol molecule CFH2OH (central atom C). On a separate page, determine the following:
(a) # of valence electrons in this molecule
(b) Plausible Lewis dot structure for this molecule that obeys the octet rule
(c) Determine the molecular shape of the molecule around the carbon atom (linear, trigonal planar, bent, trigonal pyramidal, or tetrahedral)
(d) Use electronegativity values to determine which (if any) bonds are polar (show work) (e) Determine if the molecule overall is polar or nonpolar
(f) Indicate the types of intermolecular forces that would be present between fluoromethanol molecules (list all that would be present)
(g) If you had a sample of solid fluoromethanol, how would you classify the solid and why (atomic, molecular, ionic, network covalent, metallic, etc.) Q2 Blood Iron Concentrations: Following bloodwork, a patient is found to have a blood iron molar concentration of 18.46×10-3 M Fe. Assume you have a 10.00 mL sample of this patient’s blood having a density of 0.994 g/mL. On a separate page, determine the following: (a) What is the solute of interest in this solution? (b) Determine the mass (g) of blood present in your 10.00 mL blood sample using the density (c) Determine the mass % of iron in the patient’s blood (Consider whether you need to do any unit conversions, whether you need a molar mass, whether you need to convert between grams and mols, and if you need to use the density to answer this part) (d) Blood is mostly water. Would you expect this patient’s blood sample to freeze at 0˚C, above 0˚C, or below 0˚C and WHY?
