Question 1. Draw a Lewis structure for each compound. Include all nonbonding pairs of electrons.
a) CH3CNb) CH3OCH3c) (CH3)2NH2CId) CF4e) HCO2NaNaCI
Question 2. For each compound in question 1, state whether its bonding is covalent, ionic, or a mixture of covalent and ionic.
Question 3. Using electronegativity values, identify the polar covalent bonds in the compounds in question 1 and label the atoms δ+ and δ-, as appropriate.

I dissolved .5 grams of mustard in 3 mL of distilled water. I was asked to determine the mass percentage of acetic acid in mustard, so I added 2.5 mL of NaOH to turn the mustard solution red.
Anything relevant to the course material, so thermodynamics, kinetics, quantum mechanics, or spectroscopy. No biology, pharmacology, or biochemistry.
what is the maximum number of electrons in an atom that can have the following set of quantum numbers? n 4 l 3 ml -2
A buffer solution is.290M in a weak base through kB of 2.8*10-5 and .490M in the conjugate acid, what is the pH
Free radicals are important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the actions of sunlight on air pollutants, is formed in part by the following two steps.
