You've been experiencing acid indigestion lately, and you'd like a quick fix for the problem. you do a little research on the internet and discover that your problem is caused by excess stomach acid. in the pharmacy aisles, however, you're having a little trouble deciding what to purchase to address the problem. at the pharmacy counter, the clerk recommends that you purchase pepcid ac or alka-seltzer tablets. you hypothesize that a tablet of pepcid ac can neutralize more stomach acid than a tablet of alka-seltzer. if you placed a tablet of each antacid in a beaker of acid at an initial ph of 2, which of the following experimental results would support your hypothesis? a. it took 3 minutes for the pepcid ac tablet to fully dissolve and it took 5 minutes for the alka-seltzer tablet to fully dissolve. b. after 1 hour, the ph of the solution in the pepcid ac beaker was equal to that of the ph of the solution in the alka-seltzer beaker. c. after 1 hour, the ph of the solution in the pepcid ac beaker was 7.9 and the ph of the solution in the alka-seltzer beaker was 9.6.d. after 1 hour, the ph of the solution in the pepcid ac beaker was 9.2 and the ph of the solution in the alka-seltzer beaker was 8.3

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
