Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
Answer is: The molar solubility of ba3(po4)2 is <span>6.00 x 10-39.
</span>Balanced chemical reaction: Ba₃(PO₄)₂(s) → 3Ba²⁺(aq) + 2PO₄³⁻(aq).
s(Ba₃(PO₄)₂) = 8.89·10⁻⁹ M.
[Ba²⁺] = 3s(Ba₃(PO₄)₂) = 3s.
[PO₄³⁻] = 2s.
Ksp = [Ba²⁺]³ · [PO₄³⁻]².
Ksp = (3s)³ · (2s)².
Ksp = 108s⁵.
Ksp = 108·(8.89·10⁻⁹ M)⁵.
Ksp = 108 · 5.55·10⁻⁴¹ = 6·10⁻³⁹.
An ionic compound is always an electrolyte
Answer:
The more worn-out the rock is, the older it is
Explanation:
Hello,
The different layers a rock has could be useful to date it, as long as the deepest layers account for the oldest rocks because they haven been worn out due to erosion and others natural events. Thus, one can say that the more worn-out the rock is, the older it is when we want to analyze a new section of strata.
Best regards.
A.) The reaction is Exothermic
