its kinda you just need to simplify
Explanation:
Answer:
Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
A la química a veces se le llama "la ciencia central", porque une la física con otras ciencias naturales, como la geología y la biología. La química es el estudio de la materia y sus propiedades.
Mi mala si esto no ayuda
Answer:
Ksp = 7.4x10⁻⁷
Explanation:
Molar solubility of a substance is defined as the amount of moles of that can be dissolved per liter of solution.
Ksp of Zn(OH)₂ is:
Zn(OH)₂(s) ⇄ Zn²⁺ + 2OH⁻
Ksp = [Zn²⁺] [OH⁻]²
And the molar solubility, X, is:
Zn(OH)₂(s) ⇄ Zn²⁺ + 2OH⁻
⇄ X + 2X
<em>Because X are moles of substance dissolved.</em>
<em>Ksp = </em>[X] [2X]²
Ksp = 4X³
As molar solubility, X, is 5.7x10⁻³mol/L:
Ksp = 4X³
Ksp = 4 (5.7x10⁻³mol/L)³
<h3>Ksp = 7.4x10⁻⁷</h3>
