Sodium Chloride is 0.4948 kJ/mol while Sodium Thiosulfate Pentahydrate is 0.2059 kJ/mol. Therefore, Sodium Chloride could store more energy on a per gram basis.
where, E^{o} (Ag+/Ag) = std. reduction potential of Ag+ = 0.7994 v
and Sn2+/Sn = std. reduction potential of Sn2+ = -0.14 v
Thus, E^{o}cell = 0.7994v - (-0.14v) = 0.9394 v
Now, ΔG^{o} = -nF
,
where, n = number of electrons = 2
F = Faraday's constant = 96500 C
∴ΔG^{o} = 2 X 96500 X 0.9394 = -1.18 X
Now, using Nernst's Equation we have,
![[tex]E_{cell} = 0.9394 - \frac{2.303X298}{2X96500}log \frac{0.0115}{ 3.5^{2} }](https://tex.z-dn.net/?f=%20%5Btex%5DE_%7Bcell%7D%20%3D%200.9394%20-%20%5Cfrac%7B2.303X298%7D%7B2X96500%7Dlog%20%5Cfrac%7B0.0115%7D%7B%203.5%5E%7B2%7D%20%7D%20)
E_{cell} = 0.9765 v
Finally, ΔG = -nFE = -2 X 96500 X 0.9765 = -1.88 X
It is based on Relative DENSITY.............
The density will become less, this is because thing with less density float to the top when things with more density float to the bottom. It also becomes colder.
Answer:
His drives are neither precise not accurate
Explanation:
It is true that his drives are neither precise nor accurate.
Accuracy is the exactness of measurement. It is the closeness of measured values to the true values.
In this problem, the true value is 250 yards, the measured values are 190 yards, 195 yards and 187 yards.
We can conclude that these numbers are very far from the true values. By virtue of that, they are inaccurate.
Precision is the ability to reproduce a set of experimental values. It is the closeness of the measured values to one another.
Jared failed to replicate his measured values over the three trials and so, his readings are not precise.
Therefore, his measurements are both imprecise and inaccurate.
