O CHEMICAL REACTIONS Anniston V Solving for a reactant in solution 1/5 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 iron(II) chloride, which would react with silver nitrate solution like this: FeCl,(aq) + 2 AgNO3(aq) → 2 AgCl(5) + Fe(NO3),(aq) 2 The chemist adds 11.0 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 8.9 mg of silver chloride. ol. Calculate the concentration of…

The data below was collected using the procedure described in your lab notebook: Mass (before reaction): test tube + HCl(aq) + stir bar + capsule 27.000 g Mass (after reaction): test tube + HCl(aq) + stir bar + capsule 25.000 g Volume of water displaced from the squirt bottle 146 mL Temperature of the CO2(g) 298.5 K Pressure (atm) 1.012 atm Using this data answer each of the questions below. Enter your answer to three significant figures and enter only the numerical value in the answer box. Calculate the mass of CO2(g). Calculate the number of moles of CO2(g). Calculate the density of CO2(g) in g/L. Calculate the molar mass of CO2 assuming a temperature of 298.5 K. Calculate the Gas constant, R, in L*atm/K*mol. Calculate the % error of the value of the Gas constant, R.

Use E5C.1(a) to Plot the data in excel. Place two data sets on the same graph: one for temp vs. x and one for temp vs y (remember, x and y are the mole fractions and they belong on the x-axis). Don’t forget to include the boiling points of the pure substances – they are data, too. Add a trendline (polynomial, 3rd order should work) to each of the coexistence lines separately. Scale the plot appropriately and use the graph to answer the questions. Then complete E5C.1(b)
