The methane used to obtain H₂ for NH₃ manufacture is impure and usually contains other hydrocarbons, such as propane,C₃H₈. Imagi

ne the reaction of propane occurring in two steps: \begin{equation}C₃H₈(g) + 3H₂O(g) ⇄ 3CO(g) + 7H₂(g) Kp = 8.175×10¹⁵ at 1200KCO(g) + H₂O(g) ⇄ CO₂(g) + H₂(g) Kp = 0.6944 at 1200k(b) Calculate Kp for the overall process at 1200. K.

According to the ideal gas law, partial pressure is inversely proportional to volume. It is also directly proportional to moles and temperature. At equilibrium in the following reaction at room temperature, the partial pressures of the gases are found to be PN2 = 0.094 atm, PH2 = 0.039 atm, and PNH3 = 0.003 atm.

<h3>Equilibrium partial pressures</h3>

The initial partial pressures of CO and water are 4.0 bar and 4.0 bar respectively.

The equilibrium partial pressures (in the bar) of CO, H2​O, CO2​, and H2​ are 4−p,4−p, and respectively.

Let p bar be the equilibrium partial pressure of hydrogen.

The expression for the equilibrium constant is

Kp​=PCO​PH2​O​PCO2​​PH2​​​=(4−p)(4−p)p×p​=0.1

p=1.264−0.316p

p=0.96 bar.

Rank the following from highest to lowest priority according to the Cahn-Ingold-Prelog system: -CH2CH3, -CHCH2, -CCH, -CH3.
mario62 [17]

Answer:

The order will be:

CCH > CHCH₂ > CH₂CH₃> CH₃

Explanation:

According to Cahn-Ingold-Prelog system we rank the groups based on the atomic number of directly attached atom with the chiral carbon.

For example: between C and H, we rank Carbon first.

If the same atoms are attached for different groups then we prioritized based on the second element with highest atomic number.

For example:

Among CH₃ and C₂H₅, the priority will be given to C₂H₅.

If an atom is double or triple bonded to the directly attached atom then each pi bond is considered to be a new atom.

Hence CH=CH₂ means, that there are two carbons attached to CH carbon.

So the order based on above selection rules will be:

CCH > CHCH₂ > CH₂CH₃> CH₃

9474 millimeters to centimeters using scientific notation showing work
puteri [66]

Answer:

9.474 x 10^2

Explanation:

ok. first you have to get the value in the required unit so 9474mm/(10mm/cm) = 947.4 so scientific notation states that the number must be raised to any power of an integer and the value of the number being raised must be less than than 10 and more than or equal to 1

so it must have one digit in front so.. 947.4 becomes 9.474 and because you move 2 places to the left, ur power is positive 2

and proof 10^2 is 100 so multiply 9.474 by 100 and u will get 947.4 cm which is also 9474 mm

True

Explanation:

It is correct to say that the biosphere includes all of the fish that are in the ocean. Even though the ocean is part of the hydrosphere.

The biosphere includes all life form on earth wherever they may dwell from deep abyss to the high atmosphere.

The different spheres on earth are interacting with one another and they depend on each other.

Just like the earth systems, the spheres of the earth relates with each other. Even the ocean is contained in the geosphere.
