The tendencyto ionize (i.e., the ionic strength) of a weak acid or base canbe quantified in several ways includingKa or Kb,pKa or pKb,and percent ionization.

Q1. The net potential energy between two adjacent ions, EN, is represented by A В E N pn where EN is the net energy in Joule (J), A and B are constants with values of 1.436 J.nm and 7.32 × 106 J.nm, r is the interatomic distance between the two ions in nanometer (nm), and n is a positive number with a value of 8.
PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.

Scientists can learn a great deal about a community's drug use (both legal and illegal) by analyzing the contaminants in wastewater. In a recent study in New York State, chemists measured the concentration of cotinine, a derivative of nicotine that i produced in the liver and excreted in the urine of tobacco users. The chemists found the average cotinine concentrations in the wastewater stream was 1.43 µg/L. a Ι Ι H- b HH H H-C C-N: C=0: TH HH Jonutis/Shutterstock Revell, Introductory Chemistry, 2e, © 2021 W.
