The solubility of manganese(II) sulphide is 1.7 x 10-7 M at 25 C. The solubility product constant is Select one: O a. 2.9 x 10-14 O b. 1.7 x 10-7 O c. 3.4 x 10-7 O d. 4.1 x 10-4 When equal volumes of 0.20 M KCrO4 and 0.20 M AgNO3 are mixed, a red precipitate is formed. The net ionic equation for this reaction is A. K+1 KNO3(5) B. 2Ag + CrO2, -> Ag2 CrO4(s) (aq) C. K CrO 4(04) + 2AgNO3(09) (aq) -1 +NO D. 2Ag (aq) Select one: O a. A. O b. B. O C.C. O d. D. (aq) + Cro-2 -> (aq) - Ag CrO4(s) +2KNO3(5) (aq) + 2NO1 +2K+1 - Ag CrO 4(8) + 2KNO3(s)
