At 500 degree C, F_2 gas is stable and does not dissociate, but at 840 degree C, some dissociation occurs: F_2 (g) 2 F(g). A fla
bazaltina [42]

Answer:

2.73 is the equilibrium constant for the dissociation of F_2 gas at 840 degree Celsius.

Explanation:

F_2(g)\rightleftharpoons 2F(g)

Initial

0.600 atm    0

Equilibrium

(0.600 atm - p)        2p

Total pressure at equilibrium = P = 0.984 atm

P= 0.600 atm - p)+2p=0.984 atm

p = 0.384 atm

Partial pressure of the F_2 gas , p_{f_2}= (0.600 atm - 0.384 atm)=0.216 atm

Partial pressure of the F gas, p_{f} = 2(0.384 atm)=0.768 atm

K_p=\frac{(p_{F})^2}{p_{F_2}}

K_p=\frac{(0.768 atm)^2}{0.216 atm}=2.73

2.73 is the equilibrium constant for the dissociation of F_2 gas at 840 degree Celsius.

Starting with the water in the ocean place the below steps in the correct order showing how water moves through this cycle
ruslelena [56]

Answer:

C, A, D and B

Explanation:

Water evaporates from the surface of the oceans leaving behind salts. As water vapor rises, it collects and is stored in clouds.

As water cools in the clouds, condensation occurs. Condensation is when gases turn back into liquids.

Condensation creates precipitation. Precipitation includes rain, snow, hail and sleet. The precipitation allows the water to return again to the Earth's surface.

When precipitation lands on land, the water can sink into the ground to become part of our underground water reserves, also known as groundwater.

A proton is fired toward a lead nucleus from very far away. How much initial kinetic energy does the proton need to reach a turn
Olegator [25]

Answer:

The electric force is conservative.

Since

ΔK = −ΔU,

Kf − Ki =Ui −Uf.

We have,

Kf = 0

Ui = 0.

Thus Ki =Uf.

<u>so ,at 10 fm Uf = (2×10)−12 J.</u>
