The dissolution of BaCO₃ in water is represented above. A 20.0 ml sample of 1 x 10⁻⁴ M Ba(NO₃)₂(aq) is mixed with an 80.0 ml sample of 1 × 10⁻⁴ M Na₂(CO₃)₂(aq). Which of the following correctly predicts and explains the outcome?
(A) A precipitate will form, because Q=1.0 × 10⁻⁸.
(B) A precipitate will form, because Q=1.6 × 10⁻⁹.
(C) A precipitate will NOT form, because Q=1.0 × 10⁻⁸.
(D) A precipitate will NOT form, because Q=1.6 × 10⁻⁹.
