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:
Not much heat moves into the lower levels of the ground. The heat that the ocean absorbs is mixed with the lower water quickly. ... At night, while the land cools off quickly, the water at the surface is kept warmer because the water is mixed around with the warmer water underneath.

oh wait i wrote whole paragraphs let me fix this
okay so you mean this ?
a term for disaccharides would be double sugar or boise!
monosaccharides are simple sugars soluble in water. any class of sugars like glucose.
polysaccharide is starch, cellulose, or glycogen. with molecules together. a carbohydrate.
saccharide knows as to the term structure of carbohydrates. carbohydrates are plain simple? organic compounds that are aldehyde or ketone functional group. with the general chemical formula of carbohydrates is c (H O)
