Explanation:
The given data is as follows.
MW = 29 g/mol, 
= 3.5 R
Formula to calculate minimum amount of work is as follows.
![W_{s} = C_{p}T_{1}[(\frac{P_{2}}{P_{1}})^{\frac{R}{C_{p}}} - 1]](https://tex.z-dn.net/?f=W_%7Bs%7D%20%3D%20C_%7Bp%7DT_%7B1%7D%5B%28%5Cfrac%7BP_%7B2%7D%7D%7BP_%7B1%7D%7D%29%5E%7B%5Cfrac%7BR%7D%7BC_%7Bp%7D%7D%7D%20-%201%5D)
= ![3.5 \times 8.314 J/k mol \times 306 \times [(\frac{550}{125})^{\frac{1}{3.5}} - 1]](https://tex.z-dn.net/?f=3.5%20%5Ctimes%208.314%20J%2Fk%20mol%20%5Ctimes%20306%20%5Ctimes%20%5B%28%5Cfrac%7B550%7D%7B125%7D%29%5E%7B%5Cfrac%7B1%7D%7B3.5%7D%7D%20-%201%5D)
= 4.692 kJ/mol
Therefore, total work done will be calculated as follows.
Total work done = 
Since, m = 
. Therefore, putting these values into the above formula as follows.
Total work done =
= 
= 24268.96 kJ/min
It is known that 1 kJ/min = 0.0166 kW. Hence, convert 24268.96 kJ/min into kW as follows.
= 402.86 kW
Thus, we can conclude that the minimum work required by an air compressor is 402.86 kW.
IBM and others are using copper instead of aluminum in the most powerful computer chips they manufacture. Because of copper's superior electrical conductivity, this technology enables conductor channel lengths and widths to be significantly reduced.
Answer:
Helium.
Explanation:
Hydrogen in the bomb is used in the process of detonation. A stream of tritium, an isotope of hydrogen is released and this fissionable material is very unstable thus it turns during the detonation to helium 3. This triggers a series of reactions that produce large amounts of heat to the surrounding environment causing destruction.
pretty sure its True hope this helped
Explanation:
A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. ... The magnet is attracted by the earth's magnetic north pole and always points in that direction.
Answer:
1.2×10²³ atoms.
Explanation:
Data obtained from the question include:
Mole of propanone = 0.20 mole
Number of atoms of propanone =.?
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.022×10²³ atoms.
This implies that 1 mole of propanone also contains 6.022×10²³ atoms.
Thus, we can obtain the number of atoms in 0.20 mole of propanone as illustrated below:
1 mole of propanone contains 6.022×10²³ atoms.
Therefore, 0.20 mole of propanone will contain = 0.2 × 6.022×10²³ = 1.2×10²³ atoms.
Thus, 0.20 mole of propanone contain
1.2×10²³ atoms.
