so conc. of ammonium ions =2*0.100=0.200 </span>
Answer:
The problem is solvable
Explanation:
The information that is provided, together with some equations are enough to solve the problem:
- The inlet states are totally defined.
- A heat balance under adiabatic assumption, allows to calculate the outlet temperature (both outlets stream are in equilibrium, so at the same temperature).
- The rule of phases implies that por the two-phase equilibrium, there is only one pressure for each temperature.
- The mass balance and equilibrium relationships allows to calculate the res of properties for the outlet streams.
Answer : The correct option is, (C) ![403.6cm^3](https://tex.z-dn.net/?f=403.6cm%5E3)
Explanation :
The formula used for the volume expansion coefficient is:
![V_{final}=V_{initial}\times (1+\gamma \Delta T)](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3DV_%7Binitial%7D%5Ctimes%20%281%2B%5Cgamma%20%5CDelta%20T%29)
where,
= final volume of mercury = ?
= initial volume of mercury = ![400.0cm^3](https://tex.z-dn.net/?f=400.0cm%5E3)
= volume expansion coefficient = ![180\times 10^{-6}K^{-1}](https://tex.z-dn.net/?f=180%5Ctimes%2010%5E%7B-6%7DK%5E%7B-1%7D)
= change in temperature = ![50^oC-0^oC=50^oC](https://tex.z-dn.net/?f=50%5EoC-0%5EoC%3D50%5EoC)
Now put all the given values in the above formula, we get:
![V_{final}=400.0\times [1+(180\times 10^{-6}\times 50)]](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3D400.0%5Ctimes%20%5B1%2B%28180%5Ctimes%2010%5E%7B-6%7D%5Ctimes%2050%29%5D)
![V_{final}=403.6cm^3](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3D403.6cm%5E3)
Therefore, the final volume of mercury is ![403.6cm^3](https://tex.z-dn.net/?f=403.6cm%5E3)
Number of grams in 1 mole = 6.23 * 10^23
Now, in 15, it would be: 15 / 6.23 * 10^23 = 2.5 * 10^-24 moles (approx.)
In short, Your Answer would be Option C
Hope this helps!
Answer:
A chemical equation consists of the chemical formulas of the reactants (on the left) and the products (on the right). The two are separated by an arrow symbol (“→” usually read aloud as “yields”). ... The equation also identifies that all the compounds are in the gaseous state.
