Answer : The volume for 6.0m HCl solution required = 62.5 ml
Solution : Given,
Initial concentration of HCl solution = 6.0m
Final concentration of HCl solution = 1.5m
Final volume of HCl solution = 250 ml
Initial volume of HCl solution = ?
Formula used for dilution is,
where,
= initial concentration
= final concentration
= initial volume
= final volume
Now put all the given values in above formula, we get the initial volume of HCl solution.
= 62.5 ml
Therefore, the volume for 6.0m HCl solution required = 62.5 ml
No units are provided in the data table, though one would usually assume that 0.244 is molarity of NaOH, and buret data of 14.7 is probably the final volume of NaOH in mL. No identification is given for the 38, but maybe this is the initial buret volume in mL.
If the buret was rinsed with water, it should have been left to dry for some time, or else the added water may slightly dilute the NaOH solution placed in it.
The health hazards because it is asking which human risk is the most important to consider.
b would be the best none of the rest make any sense.
Explanation:
The given reaction equation is as follows.
The value of 
= 59.1 kJ/mol
We know that
,
or, 
= -(\frac{59.1 kJ/mol}{(8.314 \times 10^{-3} kJ/mol.K \times 310 K))}[/tex]
= -22.93
or, 
= 
![K_{sp} = [Ba^{2+}][ SO_{4}^{2-}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BBa%5E%7B2%2B%7D%5D%5B%20SO_%7B4%7D%5E%7B2-%7D%5D)
Therefore, ![[Ba^{2+}] =\sqrt{K_{sp}}](https://tex.z-dn.net/?f=%5BBa%5E%7B2%2B%7D%5D%20%3D%5Csqrt%7BK_%7Bsp%7D%7D)
= 
= 
Therefore, we can conclude that the value of ![[Ba^{2+}]](https://tex.z-dn.net/?f=%5BBa%5E%7B2%2B%7D%5D)
in the intestinal tract is .
