Comparing IMF strengths between molecules of same/similar size. {Ans: Strongest to weakest: 1. polar + H-bonding 2. polar 3. non-polar (stringy) 4. non-polar (compact)}Galvanic Cells {Ans: Converts chemical potential energy of a spontaneous electron transfer reaction into electrical energy}Electromagnetic Radiation in order of increasing energy and decreasing wavelength. {Ans: Radiowave, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma ray}Acid-Base Titrations {Ans: At equivalence, all of the acid has reacted with all of the base. The volume of titrant is recorded at the end point where the indicator changes colour permanently. Titrations can be done with either: Strong A/Strong B (eq pt: pH = 7) Strong A/Weak B (eq pt: pH < 7) Weak A/Strong B (eq pt: pH > 7) Recall: pH Curves Recall: Calculation Process 1. Initial 2. Pre-Equivalence 3. At Equivalence 4. Post-Equivalence}Ionic Solids {Ans: Has ionic bonds, conductive as liquid, solubility depends on type of crystal structure}Body Centered Cubic {Ans: # of atoms = 2 coordination # = 8}Cohesive Forces {Ans: Forces between liquid molecules that hold the liquid together.}Adhesive Forces {Ans: Forces between the surface of the liquid and a surface area that pull the liquid apart.}Electrolysis {Ans: The
