A community has experienced the following exponential growth in population and water consumption. If the rate of expected population growth remains equalto the observed growth rate in the 2000s, but the per capita water consumption rate stabilizes (stays steady) at 158 gpd (gallon/day).

A sulfuric acid spill occurred on the highway after a truck containing barrels of sulfuric acid swerved out of control from a truck tire blowout.  Luckily no one got hurt in the event but there is a concern that the sulfuric acid spill may affect local ground water supply. A sample of the ground water in that area was recovered to assess the extent of contamination of the ground water supply.  In order to determine the concentration of sulfuric acid in the sample, 25.00 mL of the ground water sample was titrated with 0.133 M NaOH and you get the following data: Sodium hydroxide (initial buret reading)  0.66 mL Sodium hydroxide (final buret reading)  17.42 mL   Calculate the molarity of sulfuric acid in the ground water sample. Enter numerical answer.  Report in 3 sig figs.  Show work

A solution is prepared by adding 425g of AgNO3 to 0.150L of water at 40.0∘C. The solubility of AgNO3 at 40.0∘C is 311g100.mL. How many grams of AgNO3 are expected to precipitate if the temperature is dropped to 0.00∘C where the solubility of AgNO3 is only 122g100.mL? Give the answer with three significant figures.

A water quality monitoring found that local bayou contains 8.72x10-4 % (wt/wt) nitrate ion ( MW = 62.01 g/mol).  Yet the EPA standard for the nitrate content in a natural water body is 1.613x10-4 M or lower.  Is the mentioned bayou water in that location acceptable from the EPA standard ?   List your calculation steps (Density of bayou water is 1.0 g/mL).

Where stated, classify reactions both by the key reaction event (PPT, A/B, R/O) and by changes in composition (COM, DEC, SDP, DDP). 11. ClO2(g) + _ H2(g) → _ HCI(g) + – H20(g) balance, then classify: Calculate the following, with proper number of significant figures: To make 0.92 mol of HCI, liters at STP of ClO2(g) need to react. When 18 liters at STP of clO2(g) react, liters at STP of H2(g) react as well. When 1.84 liters at STP of H20 form, grams of HCI form also. When a count of 9.5 x 1022 H2 molecules reacts liters at STP of H20(g) form.

The recommended dose of Remdesivir is 200 mg (0.200 grams) by injection on day 1. Assuming the blood volume of the average adult is 5 liters, and the molecular weight of Remdesivir is 602.56 g/mole, what is the molarity of Remdesivir in moles/liter?   The recommended dose of Remdesivir is 200 mg (0.200 grams) by injection on day 1.
