Then there should be mostly 91 nails
They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
Answer:
Conc of Q at Equilibrium 2.1 × 10⁻³ mol/dm³
Ksp = 1.57 × 10⁻¹² mol/dm³
Explanation:
The Solubility of the Ionic compound is given by s
where s = 7 × 10⁻⁴ mol/dm³
solubility equation is given as follows
XQ₃(s) ⇄ X³⁺(aq) + 3Q⁻(aq)
s s 3s
let the concentration of each be s
The concentration of Q = 3s
⇒ [Q] = 3 × 7 × 10⁻⁴ mol/dm³
⇒ [Q] = 2.1 × 10⁻³ mol/dm³
hence,
Ksp = [X³⁺][Q⁻]³
Ksp = [s][3s]³
Ksp = [7 × 10⁻⁴ ][2.1 × 10⁻³]³
Ksp = 1.57 × 10⁻¹² mol/dm³
