How many grams of each of the following substances will dissolve in 100 ml of cold water? Consult a handbook or the Internet and cite your source. Ce(1O3)4 RaSO4 P(NO2 (NH4)2SeO4 2b.Which of these substances is least soluble on a gram-per-100 mL. basis? 3. Suppose you have a solution that might contain any or all of the following cations: Cu2+, Agt, Ba2, and Mn2. The addition of HBr causes a precipitate to form. After the precipitate is separated by filtration, H,504 is added to the supernatant liquid, and another precipitate forms. This precipitate is separated by filtration, and a solution of NaOH is added to the supernatant liquid until it is strongly alkaline. No precipitate is formed. Which ions are present in each of the precipitates? Which cations are not present in the original solution? 4. Write balanced net ionic equations for the reactions, if any, that occur between (a) Fe2S,(s) and HBr(aą), (b K2CO,(aą) and Cu(NO)(ag), () FeNO)(a) and HCl(ag), and (d) Bi(OH),(6) and HNO, (ag). a) b) c) d)

kindly answer all the questions.
