At 1000 K, Kp=19.9 for the reaction Fe2O3(s)+3CO(g)<--->2Fe(s)+3CO2(g) What are the equilibrium partial pressures of CO an

SOVA2 [1]

Answer: The equilibrium concentration of CO is 0.243 atm

Explanation:

We are given:

Initial partial pressure of carbon dioxide = 0.902 atm

As, carbon dioxide is present initially. This means that the reaction is proceeding backwards.

For the given chemical equation:

$Fe_2O_3(s)+3CO(g)\rightleftharpoons 2Fe(s)+3CO_2(g)$

Initial: 0.902

At eqllm: 3x (0.902-3x)

The expression of $K_p$ for above equation follows:

$K_p=\frac{(p_{CO_2})^3}{(p_{CO})^3}$

We are given:

$K_p=19.9$

Putting values in above equation, we get:

$19.9=\frac{(0.902-3x)^3}{(3x)^3}\\\\x=0.0810$

So, equilibrium concentration of CO = 3x = (3 × 0.0810) = 0.243atm[/tex]

Hence, the equilibrium concentration of CO is 0.243 atm

If the atomic mass is 14 and the atomic number is 7,how many neutrons do you have?

Nitella [24]

Answer: 7 neutrons

Explanation: Atomic number refers to the number of protons in the nucleus of the atom. Also you can treat atomic mass as how many particles (protons and neutrons) are in the nucleus of the atom. So for this problem:

14 particles - 7 protons = 7 neutrons (and we know all that's left over is neutrons because we subtracted all the protons)
