<u>Answer:</u> The value of
for the net reaction is 13.94
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u> ![A+2B\xrightarrow[]{K_1} 2C](https://tex.z-dn.net/?f=A%2B2B%5Cxrightarrow%5B%5D%7BK_1%7D%202C)
<u>Equation 2:</u> ![2C\xrightarrow[]{K_2} D](https://tex.z-dn.net/?f=2C%5Cxrightarrow%5B%5D%7BK_2%7D%20D)
The net equation follows:
![D\xrightarrow[]{K_c} A+2B](https://tex.z-dn.net/?f=D%5Cxrightarrow%5B%5D%7BK_c%7D%20A%2B2B)
As, the net reaction is the result of the addition of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the inverse of second equilibrium constant.
The value of equilibrium constant for net reaction is:
![K_c=K_1\times \frac{1}{K_2}](https://tex.z-dn.net/?f=K_c%3DK_1%5Ctimes%20%5Cfrac%7B1%7D%7BK_2%7D)
We are given:
![K_1=2.37](https://tex.z-dn.net/?f=K_1%3D2.37)
![K_2=0.170](https://tex.z-dn.net/?f=K_2%3D0.170)
Putting values in above equation, we get:
![K_c=2.37\times \frac{1}{0.170}=13.94](https://tex.z-dn.net/?f=K_c%3D2.37%5Ctimes%20%5Cfrac%7B1%7D%7B0.170%7D%3D13.94)
Hence, the value of
for the net reaction is 13.94
B. Increasing the effective nuclear charge on an ion results in energy levels that are closer together.
hope it helps
Answer:
1.diamond, graphite, and fullerenes.
2.a material produced by the incomplete combustion of heavy petroleum/ink for printing newspapers, as ink-jet toner, and coloring leather in shoes
3.Diamond is extremely hard while graphite is pretty soft, diamond has a greater density than graphite, and diamond is semi transparent while graphite is dark and foggy
4.Graphite can conduct electricity because of the free electrons in its structure. However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised(free) electrons.
Explanation:
Thank you for posting your question here at brainly. The <span>mole fraction of co if the h2 mole fraction is 0.22 and the o2 mole fraction is 0.58 is 0.20, below is the solution:
</span>
mole fraction CO + mole fraction H2 + mole fraction O2 = 1
mole fraction CO = 1 - ( 0.22 + 0.58)=0.20
Answer:
Iron has 5 unpaired electrons in Fe⁺³ state.
Explanation:
Iron having atomic number 26 has following electronic configuration in neutral state.
Fe = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d⁶
When Iron looses three electrons it attains +3 charge with following electronic configuration.
Fe⁺³ = 1s², 2s², 2p⁶, 3s², 3p⁶, 3d⁵
The five electrons in d-orbital exist in unpaired form as,
3(dz)¹, 3d(xz)¹, 3d(yz)¹, 3d(xy)¹, 3(dx²-y²)¹
