2. In the reaction H2(g) + b(0) + 2HI(), there are equilibrium partial pressures of PH, = 13.0 MPa, P = 11.7 MPa and Phi = 66.6

Brrunno [24]

Answer:

Equilibrium constant is equal to $29.162$

Explanation:

If the reaction is of this form

aA(g) + bB(g) ⇄ cC(g) + dD(g)

Then , the Kp of this equation will be equal to

$K_p =\frac{P_C^cP_D^d}{P_B^bP_A^a}$

Given

$P_c =$ $66.6$ MPa and c is equal to two

$P_A = 13.0$ MPa

$P_b = 11.7$ MPa

Here a and b is equal to zero.

Substituting the given values we get -

$K_p = \frac{66.6^2}{13*11.7}\\K_p = 29.162$

Equilibrium constant is equal to $29.162$

Serga [27]

Answer:

23.4 mph

Explanation:

The conversion factors are multiplied so that the units cancel out:

(100 meters / 9.58 sec) x (1 mile / 1609 meters) x (60 sec / min) x (60 min /1 hr) = 23.4 mph

A standard hydrogen atom has how many neutrons? <br>A. 2<br>B. 0<br>C. 1<br>D. 3

hoa [83]

Answer:

Explanation:

standard hydrogen is considered to be protium isotope of hydrogen that has one electron revolving around the nucleus containing one proton and no neutrons.

it's atomic number and mass number is 1

and number of neutrons = mass no. - atomic no.

= 1 - 1
