<span>When BaCrO4 dissolves, it dissociates like this: BaCrO4 (s) --> Ba2+ + CrO42-
</span>
<span>The expression for Ksp is [Ba2+] x [CrO42-]
</span>
There is a 1:1 molar ratio between the BaCrO4 that dissolves and Ba2+ and CrO42-
that are in solution. This means that, when 1.08×10⁻⁵ moles per liter of BaCrO4 dissolves, it produces 1.08×10⁻⁵ mol/L of Ba2+ and 1.08×10⁻⁵ of <span>CrO42-. So, applying the expression:
</span>
Ksp = (1.08×10⁻⁵ ) x (1.08×10⁻⁵ )
= 1.166 x 10⁻¹⁰
In my opinion the answer is D
The number of valence electrons in
will be 26.
The atom's outermost inhabited shell is where valence electrons are found. They are significant because they have a major impact on how an atom's chemical characteristics are determined.
The number of valence electron in P in 5 and number of valence electron in Cl is 7. There are one molecule of P and three molecule of Cl in
molecule. By adding all valence electrons , the total number of valance electrons will be 26.
The Lewis structure of
is shown as:
Therefore, the number of valence electrons in
will be 26.
