If a weak monoprotic acid, HA, is titrated with strong base, what is NOT true at the half equivalence point?pH = pKapH = 7.0[HA]

leonid [27]

Answer:

pH can be different from 7 ( second statement is false)

Step-by-step explanation:

since

pH=pKa + log [A-]/[HA]

at half of the equivalence point

[HA]= [A-] (third statement is true)

and therefore

pH = pKa (first statement is true)

since pH = pKa , pH can be different from 7 ( second statement is false)

According to the U.S. National Transportation Safety Board, the number of airline accidents by year from 1983 to 2006 were 23, 1

Lera25 [3.4K]

Answer:

$\bar X= 33.79167$

$s= 12.06497$

$SE= \frac{s}{\sqrt{n}}= \frac{12.06497}{\sqrt{24}}=2.463$

$Median= \frac{30+31}{2}= 30.5$

Step-by-step explanation:

For this case we have the following data:

23, 16, 21, 24, 34, 30, 28, 24, 26, 18, 23, 23, 36, 37, 49, 50, 51, 56, 46, 41, 54, 30, 40, and 31

We can calculate the sample mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= 33.79167$

Then we can calculate the standard deviation with this formula:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And replacing we got:

$s= 12.06497$

And the sample size for this case is n =24. We can calculate the standard error with this formula:

$SE= \frac{s}{\sqrt{n}}= \frac{12.06497}{\sqrt{24}}=2.463$

And the median for this case since the sample size is 24 first we need to sort the data on increasing order and we got:

16 18 21 23 23 23 24 24 26 28 30 30 31 34 36 37 40 41 46 49 50 51 54 56

And for this case the median would be the average from the position 12 and 13 and we got:

$Median= \frac{30+31}{2}= 30.5$
