3) Ammonia, NH3, is toxic to a wide range of aquatic organisms including snails, insects, and fish. The ammonium ion, NH4", is much less toxic since the cation does not diffuse rapidly across cell membranes. The US EPA limit for total ammonia in natural waters is 1.9 mg/L at pH 7. a. What is this limit in molar units? b. What is the concentration of NH3 at pH 7? c. What is the concentration of NH3 at pH 6? d. Why is the EPA limit for total ammonia dependent on the water pH?

9. Find the final concentration as a percent (w/v) of dextrose when 75 mL dextrose 50 % (w/v), 50 mL of sodium chloride 0.9 % (w/v), and 100 mL of dextrose 5 % (w/v) sodium chloride 0.45 % (w/v) solution are mixed together.
5. Note: These directions will help you collect data that will answer questions about different concentrations of a single chemical. If you have a different question, you will need to modify your data table, the data collected, and graph. 1. Identify at least 4 different concentrations of the chemical for which you wish to collect data. Type the name of your chemical at the top of the first column and record the concentrations in your data table. 2. For each concentration you will collect heart rate data for three different daphnia. a. Select a daphnia trial you wish to observe. b. Select a video speed at which you wish to count the heart beats of the daphnia. c. Count the heart beats in your selected video. d. Remember all of the videos show 15 seconds. Multiply your 15 second count by 4 to then have beats per minute for the units of heart rate. Record your heart rate calculation (bpm) in the table. e. The table is set-up to automatically calculate the average heart rate for…
