CHEM 219 MODULE 7 MASTER REVIEW
SCRIPT WITH THOROUGHLY SOLVED
QUESTIONS AND EXPERT INSIGHT
◉ Oxyacid
Answer: Any acid that contains hydrogen and an oxyanion
◉ Structural formula
Answer: A molecular model that uses symbols and bonds to show
relative positions of atoms
◉ Resonance
Answer: Condition that occurs when more than one valid Lewis
structure exists for the same molecule
◉ Coordinate covalent bond
Answer: Forms when one atom donates a pair of electrons to be
shared with an atom or ion that needs two electrons to become
stable
◉ VSEPR model
Answer: Valence Shell Electron Pair Repulsion model, which is
based on an arrangement that minimizes the repulsion of shared
and unshared pairs of electrons around the central atom
