City A: 100° F
City B: -29° F

100 - (-29) ==> 100 + 29 = 129 degrees difference.

The different between City A and B is 129° F

Hope this helps!

Write out a detailed mechanism of the acid catalyzed dehydration of cyclohexanol. use only hydronium as your acid source.
Ahat [919]
Dehydration means (removal of water molecule) and in this case a double bond is formed by removal of H and OH from two vicinal (neighboring) carbons, this occurs by protonation then lose of water molecule then lose of H⁺ (we have to add H⁺ from acid at the beginning due to OH⁻ is bad leaving group)

If the initial concentration of ab is 0.210 m , and the reaction mixture initially contains no products, what are the concentrat
Helen [10]
ANs: [A] = [B] = 0.094 M

The following reaction was monitored as a function of time: 
AB --> A + B 
A plot of 1/[AB] versus time is a straight line with slope, K = 5.5×10^−2 M * s. 

Now, 

\frac{1}{[AB]} = \frac{1}{[AB_{0} ]} + kT \\ \\ \frac{1}{[AB]} = \frac{1}{0.210} + (5.5* 10^{-2})*70 sec \\ \\ \\ \[AB] = 0.116

<span>Now, Since at 70 s, [AB] = 0.116 M,

then amount of AB lost: </span>
<span>0.210 M - 0.116 M = 0.094 M 
</span>
Now, according to the stoichiometry of the reaction, 
<span>AB : A : B = 1 : 1 : 1, 
</span>
<span>so both [A] and [B] gained the same number of moles and thus have same concentration, as [AB] lost.

So, [A] = [B] = 0.094 M after 70 s.</span>
