Answer: 0.0036
Explanation:
Initial moles of
= 2 mole
Moles of
at equilibrium= 0.25 mole
Volume of container = 10 L
Initial concentration of
equilibrium concentration of ![Cl_2=\frac{moles}{volume}=\frac{0.25moles}{10L}=0.025M](https://tex.z-dn.net/?f=Cl_2%3D%5Cfrac%7Bmoles%7D%7Bvolume%7D%3D%5Cfrac%7B0.25moles%7D%7B10L%7D%3D0.025M)
The given balanced equilibrium reaction is,
![PCL_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)](https://tex.z-dn.net/?f=PCL_5%28g%29%5Crightleftharpoons%20PCl_3%28g%29%2BCl_2%28g%29)
Initial conc. 0.2 M 0 0
At eqm. conc. (0.2-x) M xM xM
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{x\times x}{0.2-x}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7Bx%5Ctimes%20x%7D%7B0.2-x%7D)
We are given : x = 0.025 M
Now put all the given values in this expression, we get :
![K_c=\frac{0.025\times 0.025}{0.2-0.025}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B0.025%5Ctimes%200.025%7D%7B0.2-0.025%7D)
![K_c=0.0036](https://tex.z-dn.net/?f=K_c%3D0.0036)
Thus the value of the equilibrium constant is 0.0036.
Answer:
![a=4.8m/s^2](https://tex.z-dn.net/?f=a%3D4.8m%2Fs%5E2)
Explanation:
Hello,
In this case, since the acceleration in terms of position is defined as its second derivative:
![a=\frac{d^2x(t)}{dt^2}=\frac{d^2}{dt^2}(2.9+8.8t+2.4t^2)](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bd%5E2x%28t%29%7D%7Bdt%5E2%7D%3D%5Cfrac%7Bd%5E2%7D%7Bdt%5E2%7D%282.9%2B8.8t%2B2.4t%5E2%29)
The purpose here is derive x(t) twice as follows:
![a=\frac{d^2x(t)}{dt^2}=\frac{d}{dt}(8.8+2*2.4*t)\\ \\a=4.8m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bd%5E2x%28t%29%7D%7Bdt%5E2%7D%3D%5Cfrac%7Bd%7D%7Bdt%7D%288.8%2B2%2A2.4%2At%29%5C%5C%20%5C%5Ca%3D4.8m%2Fs%5E2)
Thus, the acceleration turns out 4.8 meters per squared seconds.
Best regards.
The ratio of the number of turns in the primary and the secondary coil of a step-up transformer is 1 : 200.
The formula for calculating the secondary voltage in a transformer is: N = V = Where No and N are the primary and secondary coils' respective turn counts; V and V are the RMS voltages across the primary and secondary coils, and I and Is are the primary and secondary currents.
Calculation: Due to this:
The coil's N2 to Ns turn ratio is 1/20.
We understand that N=1/20 = 4/LP: Is = 20:1.
The transformer uses the following principles: A wire's magnetic field moves as a result of a changing current flowing through it. A wire exposed to a moving magnetic field will create a changing current.One of the coils produces a magnetic field that grows and contracts in response to the changing voltage of the AC when an AC source is connected to it.
In other words, the coil generates a growing magnetic field as the voltage across it rises. The magnetic field generated around the capacitor increases when the voltage reaches its maximum and starts to decline.

Mass = Weight/g
= 1225 N/9.81 m/s^2
= 124.872579 kg
(rounded-off in 3 significant figures) = 125 kg
NOTE: I truly apologize if my answer is incorrect. I still hope this helped! :) (a brainliest would be much appreciated!)
Although Alfred Wegener was considered as the "Father of the Plate Tectonics Theory", his theory was furthermore revised by Arthur Holmes. It was this scientist who suggested that the plate motions could be subjected from convection currents on the mantle. These convection currents would lead to the formation of different landforms.
