Answer:
the process of returning a land area to the condition it was in before humans used the land
Explanation:
Reclamation refers to the process of returning a disturbed ecosystem to its original status prior to the disturbance. Often times, the disturbance regimes that change the conditions of the ecosystem are created by humans.
<em>Reclamation is unlike reforestation in that the latter involves the process of planting trees in order to reestablish forest lands, not necessarily return the land to its previous status.</em>
Reclamations are often done to return lands to the original flora and fauna status before the disturbance regime.

this is way I got for you
When PbSO₄ is added it dissociates as follows
PbSO₄ --> Pb²⁺ + SO₄²⁻
molar solubility is the number of moles of solute that can be dissolved in 1 L of solution
if molar solubility of PbSO₄ is X, then molar solubility of Pb²⁺ is X and SO₄²⁻ is X
the formula for ksp is as follows
ksp - solubility product constant
ksp = [Pb²⁺][SO₄²⁻]
ksp = X * X
ksp = X²
ksp = 1.82 x 10⁻⁸
X² = 1.82 x 10⁻⁸
X = 1.35 x 10⁻⁴ M
molar solubility of PbSO₄ is 1.35 x 10⁻⁴ M
answer is b.
