Suppose a 250. mL flask is filled with 0.20 mol of H₂S, 1.1 mol of CS2 and 1.2 mol of H₂. This reaction becomes possible: CH₂(g) + 2H₂S (g) = CS₂(g) + 4H₂(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of CH4. You can leave out the M symbol for molarity. initial change equilibrium CH4 X H₂S 0 CS2 0 H₂ 0 X S

esc 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 copper(II) chloride, which would react with silver nitrate solution like this: CuCl₂(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cu(NO3)₂(aq) C The chemist adds 90.0 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 6.0 mg of silver chloride. olla Calculate the concentration of copper(II) chloride contaminant in the original groundwater sample.

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.
