Chemistry: A Molecular Approach 3
The cyanate ion (OCN-) and the fulminate ion (CNO-) share the same three atoms but have vastly different properties. The cyanate ion is stable, while the fulminate ion is unstable and forms explosive compounds. The resonance structures of the cyanate ion were explored in Example 9.8 . Draw Lewis stru

Problem 10P Why is a quantitative observation more useful than a non- quantitative one? Which of the following are quantitative? (a) The Sun rises in the east, (b) A person weighs one-sixth as much on the Moon as on Earth, (c) Ice floats on water, (d) A hand pump cannot draw water from a well more th

Select the one false statement about mucous and serous membranes. a. The epithelial type is the same in all serous membranes, but there are different epithelial types in different mucous membranes. b. Serous membranes line closed body cavities, whereas mucous membranes line body cavities open to the
