a solution is made by dissolving cadmium fluoride (CdF2 Ksp =6.44×10 −3 ) in 100.0 mL of water until excess solid is present. So
Lunna [17]

Answer:

Answers are in the explanation

Explanation:

Ksp of CdF₂ is:

CdF₂(s) ⇄ Cd²⁺(aq) + 2F⁻(aq)

Ksp = 6.44x10⁻³ = [Cd²⁺] [F⁻]²

When an excess of solid is present, the solution is saturated, the molarity of Cd²⁺ is X and F⁻ 2X:

6.44x10⁻³ = [X] [2X]²

6.44x10⁻³ = 4X³

X = 0.1172M

<h3>[F⁻] = 0.2344M</h3><h3 />

Ksp of LiF is:

LiF(s) ⇄ Li⁺(aq) + F⁻(aq)

Ksp = 1.84x10⁻³ = [Li⁺] [F⁻]

When an excess of solid is present, the solution is saturated, the molarity of Li⁺ and F⁻ is XX:

1.84x10⁻³ = [X] [X]

1.84x10⁻³ = X²

X = 0.0429

<h3>[F⁻] = 0.0429M</h3><h3 /><h3>The solution of CdF₂ has the higher fluoride ion concentration</h3>

The Water Biome has The most biodiversity. The Desert is diffrent from the Tundra Tundra and deserts both face a scarcity in water. Therefore, the vegetation found in either biome are adapted to live in such water-barren environments. The vegetation of the tundra is also resistant to cold temperatures and winds. ... Many succulents are found in a hot and dry desert.

The representative particle for zinc is the
balandron [24]

Answer: Option B) Atom

Explanation:

An atom is the simplest particle of an element that can retain all the chemical properties of the element, and therefore take part in a chemical reaction.

Thus, an atom of zinc (Zn) represent fully the entire properties of elemental Zinc. For instance: an atom of zinc has a mass of 65.38g.
