Answer:

Clouds

Explanation:

The cloud among the given options would be visible only when the light from a different source reflects outside it. This is due to the reason as we are able to see the clouds only when the sun reflects it's light on it and we can witness it by not seeing the clouds in the sky on a shady day. Thus, <u>option D</u> is the correct answer. Sun cannot be the one as the sun itself can produce its own light and thus, a source of light. The lightning is characterized as a 'flash of light' and the flashlight also produces light.

Seven diatomic elements are H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂.

<h3>Which are diatomic molecules?</h3>

Diatomic molecules are those molecules in which two atoms of same elements are present, and they are combined to attain the stability.

The seven diatomic molecules which are exist in the chemistry are:

  • Hydrogen gas (H₂)
  • Chlorine gas (Cl₂)
  • Nitrogen gas (N₂)
  • Fluorine gas (F₂)
  • Bromine gas (Br₂)
  • Iodine gas (I₂)
  • Oxygen gas (O₂)

Hence H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂ are 7 diatomic molecules.

Nitrogen monoxide and hydrogen react to form nitrogen and water, like this: 2NO+2 H2(g)-N29)+2H2O(9) Write the pressure equilibr
lara31 [8.8K]

Answer:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp

Explanation:

The reaction is:

2NO + 2H₂ → N₂ + 2H₂O

The expression for Kp (pressure equilibrium constant) would be:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²

There is another expression for Kp, where you work with Kc (equilibrium constant)

Kp = Kc (R.T)^Δn

where R is the Ideal Gases constant

T° is absolute temperature

Δn = moles of gases formed - moles of gases, I had initially
