Answer:
a)
b)
![[PCl_5]=0.0375M](https://tex.z-dn.net/?f=%5BPCl_5%5D%3D0.0375M)
Explanation:
Hello!
a) In this case, since we can see that the second reaction is equal to the half of the first reaction, we can relate the equilibrium constants as shown below:
Thus, by plugging in the the equilibrium constant of the first reaction we obtain:
b) In this case, for the described reaction we can write:
Thus, the corresponding equilibrium expression is:
![K=\frac{[PCl_3][Cl_2]}{[PCl_5]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BPCl_3%5D%5BCl_2%5D%7D%7B%5BPCl_5%5D%7D)
In such a way, since we know the equilibrium constant and the concentrations of PCl3 and Cl2 at equilibrium, we can compute the concentration of PCl5 at equilibrium as follows:
![[PCl_5]=\frac{[PCl_3][Cl_2]}{K}\\](https://tex.z-dn.net/?f=%5BPCl_5%5D%3D%5Cfrac%7B%5BPCl_3%5D%5BCl_2%5D%7D%7BK%7D%5C%5C)
![[PCl_5]=\frac{\frac{0.20mol}{4L} *\frac{0.12mol}{4L} }{0.04}](https://tex.z-dn.net/?f=%5BPCl_5%5D%3D%5Cfrac%7B%5Cfrac%7B0.20mol%7D%7B4L%7D%20%2A%5Cfrac%7B0.12mol%7D%7B4L%7D%20%7D%7B0.04%7D)
Best regards!
B) polymerization
Polymer is the plural of monomers basically.
Answer:
Carbon monoxide is not breathable.
Explanation:
If you breath in Carbon monoxide you'll first pass out from the lack of Oxygen. If Oxygen does not reach your lungs in time death will occur from suffocation.
Answer:
Methyl group
Explanation:
From the diagram shown, we can see that the family group CH3 is attached to the structure.
This is simply called a methyl group because it is derived from me than and written that way to show the direct bonding between carbon and the 3 hydrogen atoms.
Each carbon atom is covalently bonded to four other carbon atoms. A lot of energy is needed to separate the atoms in diamond. This is because covalent bonds are strong, and diamond contains very many covalent bonds. This makes diamond's melting point and boiling point very high.
