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…

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)

OSHA's Hazard Communication Standard requires chemical manufacturers to evaluate hazards relating to their products and provide a Safety Data Sheet in accordance to the Globally Harmonized System (GHS) in which the use of pictograms (see Figure 1) is required to communicate hazard information. Predict (with reasons) two (2) hazards related to each of the two activities below, and assign two (2) relevant pictograms listed in Figure 1 to each of the two activities. Activity 1: Removing diethyl ether (last opened in 2019) using a rotary evaporator. Activity 2: Using carbon monoxide gas as a reducing agent to reduce iron chloride. Figure 1.
