On the picture provided only the C and D are the answer because two only of the chair conformation is in equilibrium. Equilibrium means a state where the opposing force or influence is a balance. The force is in balance because they insert an equal action for the opposing force.
Answer:
(a) 
(b) 
Explanation:
Hello,
(a) In this case, for the given chemical reaction, the law of mass action becomes:
![Kc=\frac{[C6H5CHO][H2]}{[C6H5CH2OH]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BC6H5CHO%5D%5BH2%5D%7D%7B%5BC6H5CH2OH%5D%7D)
In such a way, as 1.20 g of benzyl alcohol are placed into a 2.00-L vessel, the initial concentration is:
![[C6H5CH2OH]_0=\frac{1.20g*\frac{1mol}{108.14g} }{2.00L} =5.55x10^{-3}M](https://tex.z-dn.net/?f=%5BC6H5CH2OH%5D_0%3D%5Cfrac%7B1.20g%2A%5Cfrac%7B1mol%7D%7B108.14g%7D%20%7D%7B2.00L%7D%20%3D5.55x10%5E%7B-3%7DM)
Hence, by writing the law of mass action in terms of the change 
due to equilibrium:
Solving for by using a quadratic equation one obtains:
Thus, the equilibrium concentration of benzyl alcohol is computed:
![[C6H5CH2OH]_{eq}=5.55x10^{-3}M-5.50x10^{-3}M=5x10^{-5}M](https://tex.z-dn.net/?f=%5BC6H5CH2OH%5D_%7Beq%7D%3D5.55x10%5E%7B-3%7DM-5.50x10%5E%7B-3%7DM%3D5x10%5E%7B-5%7DM)
With that concentration the partial pressure results:
![p_{C6H5CH2OH}=[C6H5CH2OH]_{eq}RT =5x10^{-5}\frac{mol}{L} *0.082\frac{atm*L}{mol*K}*523K \\p_{C6H5CH2OH}=2.14x10^{-3}atm](https://tex.z-dn.net/?f=p_%7BC6H5CH2OH%7D%3D%5BC6H5CH2OH%5D_%7Beq%7DRT%20%3D5x10%5E%7B-5%7D%5Cfrac%7Bmol%7D%7BL%7D%20%2A0.082%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2A523K%20%5C%5Cp_%7BC6H5CH2OH%7D%3D2.14x10%5E%7B-3%7Datm)
(b) Now, the fraction of benzyl alcohol that is dissociated relates its equilibrium concentration with its initial concentration:
Best regards.
Answer:
K = 0.167
Explanation:
The equilibrium constant, K of a reaction, is defined as the ratio of the concentrations of products and concentrations of reactants.
For the reactions:
A + B ⇄ C + D
For the definition, K is:
K = [C] [D] / [A] [B]
K = [4.0M] [4.0M] / [9.6M] [10.0M]
<h3>K = 0.167</h3>
Answer:
Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.
3,5, and 1 i think maybe i uhm yeah
