<u>Answer:</u> The equilibrium constant for the total reaction is 
<u>Explanation:</u>
We are given:
We are given two intermediate equations:
<u>Equation 1:</u> 
The expression of 
for the above equation is:
![K_{c_1}=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=K_%7Bc_1%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
![0.282=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=0.282%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
.......(1)
<u>Equation 2:</u> 
The expression of 
for the above equation is:
![K_{c_2}=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K_%7Bc_2%7D%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
![41=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=41%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
......(2)
Cubing both the sides of equation 2, because we need 3 moles of HI in the main expression if equilibrium constant.
![(41)^3=\frac{[HI]^6}{[H_2]^3[I_2]^3}](https://tex.z-dn.net/?f=%2841%29%5E3%3D%5Cfrac%7B%5BHI%5D%5E6%7D%7B%5BH_2%5D%5E3%5BI_2%5D%5E3%7D)
Now, dividing expression 1 by expression 2, we get:
![\frac{K_{c_1}}{K_{c_2}}=\left(\frac{\frac{[NH_3]^2}{[N_2][H_2]^3}}{\frac{[HI]^6}{[H_2]^3[l_2]^3}}\right)\\\\\\\frac{0.282}{68921}=\frac{[NH_3]^2[I_2]^3}{[N_2][HI]^6}](https://tex.z-dn.net/?f=%5Cfrac%7BK_%7Bc_1%7D%7D%7BK_%7Bc_2%7D%7D%3D%5Cleft%28%5Cfrac%7B%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D%7D%7B%5Cfrac%7B%5BHI%5D%5E6%7D%7B%5BH_2%5D%5E3%5Bl_2%5D%5E3%7D%7D%5Cright%29%5C%5C%5C%5C%5C%5C%5Cfrac%7B0.282%7D%7B68921%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%5BI_2%5D%5E3%7D%7B%5BN_2%5D%5BHI%5D%5E6%7D)
![\frac{[NH_3]^2[I_2]^3}{[N_2][HI]^6}=4.09\times 10^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNH_3%5D%5E2%5BI_2%5D%5E3%7D%7B%5BN_2%5D%5BHI%5D%5E6%7D%3D4.09%5Ctimes%2010%5E%7B-6%7D)
The above expression is the expression for equilibrium constant of the total equation, which is:
Hence, the equilibrium constant for the total reaction is

Equate the gravitational force to the electrostatic force:
<span>KC²/D² = Gm²/D² → C = m√[G/K] = 7.6√[6.67E-11/9E9] = 6.54E-10 coulombs </span>
<span>Number of electrons N = 6.24E18*C = 4.083E9 electrons</span>
To dilute a solute in a solution, it is necessary to add a proper solvent for the reaction to occur, and adding more solvent will cause the solution to dilute even more, therefore the best answer will be letter B
For sodium, it has 1 valence electron
For oxygen, it has 6 valence electrons
For iron, it has 2 valence electrons
Answer:
A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types.
