Explanation:
Formula for compressibility factor is as follows.
z = 
where, z = compressibility factor for helium = 1.0005
P = pressure
= molar volume
R = gas constant = 8.31 J/mol.K
T = temperature
So, calculate the molar volume as follows.
= 
= 0.0056 
As molar mass of helium is 4 g/mol. Hence, calculate specific volume of helium as follows.
= 
= 0.00139 
= 0.00139 
= 1.39 
Thus, we can conclude that the specific volume of Helium in given conditions is 1.39 .
The answer is B. They all have backbones. They can all do many tasks and their backbone allows them to do so. All mammals have backbones. Although an alligator is a reptile it still has a backbone
Answer:
The value is 
Explanation:
From the question we are told that
The equation is 
The temperature is ![T = 25^oC = 298 K [room \ temperature ]](https://tex.z-dn.net/?f=%20T%20%3D%2025%5EoC%20%3D%20%20298%20K%20%20%20%5Broom%20%20%5C%20temperature%20%5D)
The emf at standard condition is 
Generally at the cathode
At the anode
Generally for an electrochemical reaction, at room temperature the Gibbs free energy is mathematically represented as
Here n is the no of electron with value n = 6
F is the Faraday's constant with value 96487 J/V
=> 
=> 
This Gibbs free energy can also be represented mathematically as
Here R is the cell constant with value 8.314J/K
K is the equilibrium constant
From above
=> 
Generally antilog = 2.718
=>
=>
Explanation:
To remove the salt from the oil, I will add water to dissolve the salt from it.
Oil is an organic molecule that is non-polar
Salt is polar ionic compound
Salt will not dissolve in the oil.
- Take the mixture.
- Add water to it.
- Water and oil are immiscible
- Shake the new heterogeneous mixture vigorously.
- leave to settle.
- Oil will come on top of the water.
- You can skim off the oil layer on top.
- Then heat the water and salt solution.
- This leaves the oil behind.
