An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

Answer:
2.06 × 10⁻¹⁰
Explanation:
Let's consider the solution of a generic compound AB₂.
AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
We can relate the molar solubility (S) with the solubility product constant (Kps) using an ICE chart.
AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
I 0 0
C +S +2S
E S 2S
The solubility product constant is:
Kps = [A²⁺] × [B⁻]² = S × (2S)² = 4 × S³ = 4 × (3.72 × 10⁻⁴)³ = 2.06 × 10⁻¹⁰
The answer is D. 62 Steering Wheels

Answer:
1 mile = 1,609 meters
3.02E6 mi^2 x (1609^2m^2/mi^2) = 7.818E12 m^2
1 in= 2.54 cm => 2 in = 5.08cm = .0508m
7.818E12 m^2 x .0508m = 3.97E11 m^3
1 cubic meter = 1,000,000 cubic centimeters
3.97E11 m^3 x (1,000,000 cm^3 / m^3) = 3.97E17 cm^3
1000 cm^3 = 1L
3.97E17 cm^3 x (1L / 1000cm^3) = 3.97E14 L
or 3.97 x 10^14 L
convert to grams since 1L is 1000g
(3.97x10^14) x1000g which is 3.974x10^ 17g which is the final ans
