A solution of hydrochloric acid accidentally leaks into a spring fed freshwater lake, which in turn feeds a single stream. the acid leaks into the lake at a rate of 2 gallons per hour and has a concentration if 3 pounds per gallon. The lake initially contains 4000 gallons of water. Water flows into the lake from the spring at a rate of 100 gallons per hour and fluid flows out of the lake into the stream at a rate of 100 gallons per hour.
a) Set up the initial value problem that models the dynamics if acid in the lake.
b) Solve the initial value problem from part a.
c) compute the amount of acid in the lake after 1 hour

Expert Solution

Given that

the lake at a rate of 2 gallons per hour and has a concentration if 3 pounds per gallon

The lake initially contains 4000 gallons of water

Water flows into the lake from the spring at a rate of 100 gallons per hour

fluid flows out of the lake into the stream at a rate of 100 gallons per hour.

2. In manufacture of chlorine, feed containing hydrochloric acid gas and air are fed to the reactor. The product gases leaving the reactor are found to contain 13.2% HCl, 6.3% 02, 42.9% N2, 30% Cl2 and 7.6% H2O (by weight). Calculate: i) The percent excess air used. ii) The composition of gases entering reactor iii) The degree of completion of oxidation (conversion) (Hint: Start solving by change the mass flow rate to mol flow rate first.)

Concentrated hydrochloric acid solution is 37.0% HCL and has a density of 1.19g/ml. A dilute solution of HCL is prepared by diluting 4.50mL of this acid to 100.00mL with water. Then 10.0mL of the dilute HCL is used for the reaction with AgNO3 solution as shown below: HCL(aq)+AgNO3(aq) to HNO3(aq)+AgCL(s) How many mL of 0.1105M AgNO3 solution is required to precipitate all of the chloride as AgCl(s)? Please show how you get the answer. Thank you!

Calculate the molarity of a solution made by adding 25.4 mL of concentrated hydrochloric acid (37.3 % by mass, density 1.19 g/mL) to some water in a volumetric flask, then adding water to the mark to make exactly 500 mL of solution. (It is important to add concentrated acid or base to water, rather than the other way, to minimize splashing and maximize safety.)
