how many moles of methane are produced when 25.1 moles of carbon dioxide gas react with excess hydrogen
Dafna11 [192]
The chemical equation for this reaction is this:
CO2 + 4H2 = CH4 + 2H2O
 from the equation, the mole ration of CO2 to CH4 is ratio 1:1
and CH4 = 25.1
The mole ratio of H2 to H2O is 4:2
therefore, mole of H2 = 19.1* 4/2 = 38.2
The moles of methane produced is 38.2 moles

The wavelength of a photon that has an energy of 7.53* 10^-32
Molodets [167]

Answer:

= 2.64 × 10^7 m

Explanation:

Energy is given by the formula;

E = hc/λ

Where h is Planck’s constant (= 6.626 x 10^-34 Js), c is the speed of light (3.00 x 108 m/s) and λ is the wavelength in meters.

Therefore, wavelength will be given by;

λ = hc/E

  = (6.626× 10^-34 × 3 × 10^8)/(7.53 × 10^-32)

<u>   = 2.64 × 10^7 m</u>

8. Zeolite is used to remove moisture from methane. A vertical column is filled with 1000.0 kg of dry zeolite. The zeolite has t
Natasha_Volkova [10]

Answer:

Follows are the solution to this question:

Explanation:

Methane inlet humidity content of =7.00\%

Methane moisture outlet content =0.05\%

Zeolite absorption humidity = 6.95\%

Dry zeolite 1 kg will accommodate water= 0.1000 \ kg

One kilogram of Dry Zeolite will carry water from =0.1000\ kg

The water can contain 1000 kg of zeolite = 100 \ kg

Methane which would be made =\frac{100}{6.95\%}= 1,439 \ kg

That's why it will be producing 1439 kg of methane.
