When the carbon-carbon bonds in ethane (C2H6), ethane
(C2H4), and benzene (C6H6) are arranged in order of
increasing length (shortest bonds first) what is the correct
order? - ....ANSWER...C2H4 < C6H6 < C2H6


These two electron-dot formulas for carbon dioxide both
satisfy the octet rule, but one is preferred over the other.
Which of the statements identifies the preferred structure
and also the reason it is preferred? -
....ANSWER...Structure 2 is preferred because the formal
charge on each atom is zero

i
water Kf=1.86*C/molal
Van't Hoff Factor (i) :how much particle dissolves
-ionic compounds separate in solution --depending how
many ions they have
-molecular compounds don't separate at all
