Answer:
Ksp = 3.47x10⁻⁹
Explanation:
When Lead (II) iodide (PbI₂) is added to water, the equilbrium produced is:
PbI₂(s) → Pb²⁺(aq) + 2 I⁻(aq)
And solubility product constant, ksp is:
Ksp = [Pb²⁺] [I⁻]²
A solubility of 9.54x10⁻⁴ M means the maximum concentration of Pb²⁺ is 9.54x10⁻⁴ M and 9.54x10⁻⁴ M×2 of I⁻. Replacing in ksp formula:
Ksp = [9.54x10⁻⁴] [2×9.54x10⁻⁴]²
<em>Ksp = 3.47x10⁻⁹</em>
Answer: The most commonly cited impact is deforestation, i.e., the clearance of forest or woodland. At a small spatial scale this may indeed be the case but on a larger landscape scale charcoal production most frequently results only in forest degradation. The contribution of charcoal to deforestation in the tropics is less than 7%. Charcoal production most frequently results in forest degradation. Most charcoal areas have the potential for rapid forest recovery.

Answer:
<em>In the given question Brianna is trying to make a </em><em>whole figure by combining different single elements.</em>
Explanation:
Here are the different coloured that are used to join and make one piece this method that Brianna is following is called synthesis.
The combination here is of simple substances that are combined directly to make a complex compound. The compound formed is complex while the substances that combined together can be element or compound or a combination of both.
