Chapter 8, Problem 8.123QA
Interpretation Introduction

To find:

Range for perchlorate concentration in drinking water of 4 to 18μg/L. The perchlorate concentration in stream averages 700.0μg/L, and the stream flows at an average rate of 161  million gallons per day (1 gal = 3.785 L).

a) What are the formulas of sodium perchlorate and ammonium perchlorate?

b) Calculate the kilograms of perchlorate flow from the Las Vegas stream into Lake Mead each day from the given data.

c) What volume of perchlorate-free lake water would have to mix with the stream water each day to dilute the stream’s perchlorate concentration from 700.0 to 4μg/L?

d) Since 2003, the states of Maryland (MD), Massachusetts (MA), and New Mexico (NM) have limited perchlorate concentrations in drinking water to 0.1μg/L. Five replicate samples were analyzed for perchlorates by laboratories in each state and the following data (μg/L) were collected:

MD MA NM
1.1 0.90 1.2
1.1 0.95 1.2
1.4 0.92 1.3
1.3 0.90 1.4
0.9 0.93 1.1

Which of the labs produced the most precise analytical results?

You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: xi 1. ☑ 2. H₂O хе i Draw the missing reagent X you think will make this synthesis work in the drawing area below. If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐
Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे
For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
