One day in lab, while taking apart a complicated distillation apparatus, your friend Mai (an expert chemist) says this: "Metal sulfides react with strong acids to produce hydrogen sulfide and a salt." Using Mai's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! FeS (s) + HCl(aq) → 0 - 0-0 On NO 0+0 REACTION

Identify each of the following reactions as a synthesis, decomposition, single displacement, or double displacement reaction. 1. N(g) +3H;(g)→ 2NH,(g) 2. 2AI(s) + 3CUO(s)Al,O:(s) +3Cu(s) 3. CACO,(s)CaO(s)+CO,(g) 4. 2Li(s) + Br.(g)→ 2LİBI(s) 5. 3Sn(NO,)(aq) + 4K,PO.(aq)12KNO.(aq) +Sn:(PO)(s) 6. Mg(s) + 2HCI(aq) MgCl,(aq) + H(g) 7. Copper displaces silver in aqueous silver nitrate in a single displacement reaction as follows. Cu(s) + 2A9NO,(aq) → 2Ag(s) +Cu(NO,).(aq) a) If zinc replaces copper, will a single displacement reaction still occur? b) If a single displacement reaction occurs, predict the products of the reaction.

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 200. mL sample of groundwater known to be contaminated with cadmium chloride, which would react with silver nitrate solution like this: CdCl2(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cd (NO3)2(aq) The chemist adds 89.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 5.4 mg of silver chloride. Calculate the concentration of cadmium chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits. E d OL E
