Answer:
D
Explanation:
According to IUPAC nomenclature, a negative polyatomic ion has its name ending in 'ate' or 'ite'
As in carbonate (CO3^2-)
Arsenite (AsO3-)
The percent yield of a chemical reaction is calculated by dividing the actual yield (determined through experimentation) by the theoretical yield (calculations). The percent yield is a great way of determining the efficiency of a reaction. For this problem, the percent yield is 83.93% as given by the solution:
% yield = (47/56)*100 = 83.93%
Not sure about the number of significant figures; you can decide where to round, but I would probably say 0.075mol.
<span>Silver oxalate dissociation equation is following:
</span><span>
Ag</span>₂C₂O₄(s) ⇄ 2Ag⁺(aq) + C₂O₄²⁻(aq)
According to reaction follows next stoichiometric ratio:
[Ag⁺] : [C₂O₄²⁻] = 2 : 1
[C₂O₄²⁻] = [Ag⁺] / 2
[C₂O₄²⁻] = (1.7×10⁻⁴)/2 = 8.5×10⁻⁵ M
So, solubility product constants for silver oxalate is:
Ksp = [Ag⁺]² x [C₂O₄²⁻]
Ksp = [1.7×10⁻⁴]² x [8.5×10⁻⁵]
Ksp = 2.46×10⁻¹²
