Answer:
The pressure is 16, 9 atm
Explanation:
We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K
PV=nRT P =(nRT)/V
P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm
The ballon would have deflated in order to decrease the volume
Answer:
Scientists believe that comets are the debris left from the solar nebula which condensed to form the Sun and planets in our solar system. Most comets are thought to originate in a huge cloud called the Oort Cloud. ... Comets follow a regular orbit around the Sun.
Hope this helps! :)

Answer:
Keq=0.866
Explanation:
Hello,
In this case, the undergone chemical reaction is:
![N_2O_42NO_2](https://tex.z-dn.net/?f=N_2O_4%3C-%3E2NO_2)
In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount (
) was:
![x=0.04mol-0.0055mol=0.0345mol](https://tex.z-dn.net/?f=x%3D0.04mol-0.0055mol%3D0.0345mol)
In addition, the produced amount of NO₂ is:
![2*0.0345mol=0.069mol](https://tex.z-dn.net/?f=2%2A0.0345mol%3D0.069mol)
Finally, considering the flask's volume, the equilibrium constant is then computed as follows:
![Keq=\frac{(2*0.0345M)^2}{0.0055M}=0.866](https://tex.z-dn.net/?f=Keq%3D%5Cfrac%7B%282%2A0.0345M%29%5E2%7D%7B0.0055M%7D%3D0.866)
Best regards.
