Answer:
[Cl⁻] = 0.016M
Explanation:
First of all, we determine the reaction:
Pb(NO₃)₂ (aq) + MgCl₂ (aq) → PbCl₂ (s) ↓ + Mg(NO₃)₂(aq)
This is a solubility equilibrium, where you have a precipitate formed, lead(II) chloride. This salt can be dissociated as:
PbCl₂(s) ⇄ Pb²⁺ (aq) + 2Cl⁻ (aq) Kps
Initial x
React s
Eq x - s s 2s
As this is an equilibrium, the Kps works as the constant (Solubility product):
Kps = s . (2s)²
Kps = 4s³ = 1.7ₓ10⁻⁵
4s³ = 1.7ₓ10⁻⁵
s = ∛(1.7ₓ10⁻⁵ . 1/4)
s = 0.016 M
A change to any gas in the atmosphere affects energy absorbed by the surface in the same way of green house effect.
<h3>What is green house effect?</h3>
Green house effect is a phenomena in which energy from the sun comes to the earth and the gases which are present in the atmosphere of the earth absorbs the energy from the sun and raises earths temperature.
The gases which are especially responsible for this effect are carbon dioxide, methane, nitrous oxide, ozone and vapors of water. Change in the concentration of this gases will affect the energy absorbed by the surface.
Hence, this is same like green house effect.

Explanation:
The fate of a protein with an N-terminal hydrophobic sorting signal and an additional internal hydrophobic domain of 22 amino acids.When it is in the translocation channel and emitted laterally into the membrane, the hydrophobic region is known as a trans-membrane domain.
