Chapter 18, Problem 44E
The Ogallala aquifer described in the Close Look box in Section 18.3, provided 82% of the drinking for the people who live in the region, although more than 75% of the water that is pumped from it is for irrigation. Irrigation withdrawals are approximately 18 billion gallons per day.
- Assuming that 2% of the rainfall that falls on an area of 600,000 km2 recharges the aquifer, what average annual rainfall would be required to replace the water removed for irrigation?
- What process or processes accounts for the presence of arsenic in well water?

Chlor-alkali plants electrolyze NaCl to produce the commodity chemicals caustic soda and chlorine gas. Industrial waste effluent released into waterways from these plants can contain trace amounts of mercury. Legally, the effluent can contain up to 2.50 x 10-9 mol/L of mercury. Determine the minimum volume of water, in megalitres (ML), that must be added to a 1.13 g sample of mercury to dilute the effluent to acceptable levels.(Do not show your work in the space provided; record only your final answer with the correct number of significant digits and the proper units.)
Chlor-alkali plants electrolyze NaCl to produce the commodity chemicals caustic soda and chlorine gas. Industrial waste effluent released into waterways from these plants can contain trace amounts of mercury.
Legally, the effluent can contain up to 2.50 x 10-9 mol/L of mercury. Determine the minimum volume of water, in megalitres (ML), that must be added to a 1.14 g sample of mercury to dilute the effluent to acceptable levels.
Record only your numerical answer with the correct number of significant digits. You do not need to include units as the units appear for you beside the answer box already.

In order to remove the phosphate ions from the drinking water, a solution of calcium hydroxide can be added. As a result, a solid Ca5OH(PO4)3 is formed and isolated by filtration and a hydroxide ion are also formed.

- Imagine that you were the chief engineer for NASA's Apollo 13 mission to the moon. The air filter which they had been using is fully saturated and no longer works. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You remember that the astronauts have a container of 14.5 kg of sodium hydroxide on the ship. As a chemical engineer, you know that sodium hydroxide can be used to remove carbon dioxide from the air by producing sodium carbonate and dihydrogen monoxide. How many liters of carbon dioxide are cleaned by the amount of sodium hydroxide given in the problem? The astronauts have 3 days left before they land on earth. You know that there are 4 astronauts, and each astronaut emits roughly 700 grams of carbon dioxide (CO2) each day. • How many liters of CO2 are produced by the astronauts? • Is there enough NaOH for the astronauts to survive the rest of their trip?
