Calculate the Ion Product Value, Q _sp, for MgCO₃ When

Calculate the ion product value, Q _sp, for MgCO₃ when a 7.0×10 ^{- 5} M aqueous solution of Mg(NO₃) ₂ is mixed with a 5.0×10 ^{- 4} M aqueous solution of Na₂CO₃. If the solubility product constant, K _sp, for MgCO₃ is 3.5×10 ^{- 8}, which statement below is true?

A) Q _sp < K _sp and a precipitate of MgCO₃ will form.
B) Q _sp > K _sp and a precipitate of MgCO₃ will form.
C) Q _sp = K _sp and a saturated solution of MgCO₃ forms.
D) Q _sp < K _sp and a precipitate of MgCO₃ does not form.
E) Q _sp > K _sp and a precipitate of MgCO₃ does not form.
