Liquid bromine dissolves readily in aqueous NaOH: Br2(€) + 2 NaOH(aq) NaBr(aq) + NaOBr(aq) + H,O(€) Suppose 2.88 × 10-3 mol of Br2(e) is sealed in a glass cap- sule that is then immersed in a solution containing excess NaOH(aq). The capsule is broken, the mixture is stirred, and a measured 121.3 J of heat evolves. In a separate experiment, simply breaking an empty capsule and stirring the solution in the same way evolves 2.34 J of heat. Com- putc the heat cvolvcd as 1.00 mol Br,(l) dissolves in excess NaOH(aq).

Cerium(IV) sulfate is used to titrate a solution of tin(II) ions, with which it reacts according to 2ce4+ (aq) + Sn²(aq)2Ce³(aq) + Sn**(aq) A cerium(IV) sulfate solution is prepared by dissolving 39.77 g of Ce(SO4)2 in water and diluting to a total volume of 1.000 L. A total of 15.83 mL of this solution is required to reach the endpoint in a titration of a 100.0-ml sample containing Sn²* (aq). Determine the concentration of Sn²* in the original solution. M

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 250. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution like this: FeCl₂(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Fe(NO3)₂(aq) The chemist adds 16.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 2.0 mg of silver chloride. Calculate the concentration of iron(II) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits. mg 0 L x10 X Ś
