Working Principle: Dalton's Law of Partial Pressure

To solve for the pressure of hydrogen gas, we just simply subtract the water vapor pressure to the total pressure.

Pressure of Hydrogen (H2) = Total pressure - H2O vapor pressure
Pressure of Hydrogen (H2) = 759.2 torr - 23.8 torr = 735.4 torr

<em> ANSWER: 735.4 torr</em>

The partial pressure of Hydrogen gas can directly be calculated by simply taking the difference of the overall pressure and the vapour pressure of water. That is:

 

P (H2 gas) = 759.2 torr – 23.8 torr

<span>P (H2 gas) = 735.4 torr</span>

What Happens During Fermentation?
Stella [2.4K]

Answer:

Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.

Sometimes bacteria perform fermentation, converting carbohydrates into lactic acid...

The frequency of an x-ray wave is 3.0 x 1012 MHz. Its wave speed is 3.0x 108 m/s. Calculate the wavelength of the x-ray wave bel
elena55 [62]

Answer:

λ = 1*10⁻¹⁰m

Explanation:

Frequency (f) = 3.0*10¹²MHz = 3.0*10¹⁸Hz

Speed (v) = 3.0*10⁸m/s

Speed (v) of a wave = frequency (f) * wavelength (λ)

V = fλ

Solve for λ,

λ = v / f

λ = 3.0*10⁸ / 3.0*10¹⁸

λ = 1*10⁻¹⁰m

λ = 0.
