Molar mass of N2 = 28

Moles of N2 = 25 / 28 = 0.89

So, moles of NH3 produce = 2 x 0.89 = 1.78

Note: H2 is in excess. so no need to care about it.

What role do hydrogen ions play in the electron transport chain high?

jeka94

They are pumped across the mitochondrial inner membrane against their concentration gradient (to where their concentration is high); as the H+ ions flow back to where their concentration is low, they drive ATP synthase to form ATP

From Young's experiment, how does the frequency of light affect the number of lines observed?

Marina CMI [18]

Answer : (C) "Higher frequencies have larger spaces between lines".

Explanation:

In Young's experiment, the condition for constructive interference is given by :

$dsin\theta=n\lambda$ .........(1)

n is order or number of lines observed

d is distance between slits

$\theta$ is the angle between the path and the line from screen to the slits.

We also know that, $c=\nu \lambda$

or

$\lambda=\dfrac{c}{\nu}$

where,

c is the speed of light

$\nu$ is frequency

$\lambda$ is wavelength

So, equation (1) turns into

$dsin\theta=n\dfrac{c}{\nu}$

$\nu=\dfrac{n\ c}{d\ sin\theta}$

So,

$\nu\propto n$

or

Higher frequencies have larger spaces between line.

So, correct option is (C).
