One hundred milliliters of 0.0010 M Ba(NO3_3)2_2 are mixed with 100 mL of 0.020 M Na2_2SO4_4. The solubility product of BaSO4_4 is 1.1×10−101.1\times10^{-10}. Which option gives the correct reaction quotient QQ for BaSO4_4 after mixing and predicts whether a precipitate forms? a) Q=2.0×10−5;Q=2.0\times10^{-5}; BaSO4_4 precipitates b) Q=5×10−6;Q=5\times10^{-6}; BaSO4_4 precipitates c) Q=2.5×10−3;Q=2.5\times10^{-3}; BaSO4_4 precipitates d) Q=5×10−6;Q=5\times10^{-6}; BaSO4_4 does not precipitate
