<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
Answer:
A. absorbs light
Explanation:
For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.
In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.
When said electron comes back to the lower energy level, the atom will conversely give off light.
The most stable oxide is this francium oxide A) Fr2O
The answer is A. An sp3 hybridized atom will have a total of 4 single bonds and lone pairs. Since carbon here is attached to four hydrogens, it must be sp3 hybridized. The C-H bonds are also the least polar bonds here, even though there is a slight amount of electronegativity difference between the two.
