- 5. A student mixed 5 mL of 3% m/v H202 with 10 mL of 0.5M IKI solution and measured the volume of water displaced over time. Use their data to prepare a plot of volume water displaced (mL) versus time (s) in Excel and find the rate of this run. Attach your spreadsheet and plot to your pre-laboratory assignment. Volume of Water Displaced (mL) Time (s) 2.0 39 4.0 76 6.0 106 8.0 137 10.0 166 12.0 192 14.0 222 16.0 242 18.0 20.0 270 302 Rate =Trial [I0:] [HSO: ] Time Rate [HSO3 ]/time 1 49 25 3 16.9 Table-2 Find the concentrations of [IO3] and [HSO3] and enter into the table. Divide the concentration of HSO3 with the time in seconds to get the rate. Volume is assumed to be additive in this experiment. Thus, the total volume of all the solutins is assumed to be 20.0 mL. This introduces a small error that can be considered insignicant. The concentrations of IO; and HSO, (after mixing but before the reaction begins) can be calculated using the relationship: Mailute Vdilute= Mcone Vcone. A sample calculation is shown below for the concentration of IO, in Trial 1: Mailute to be calculated Vdilue 20.0 mL 0.020 M x 2.0 mL Mcone 0.020M V conc 2.0 mL %3D diluted [IO, ] = = 0.0020 M IO, %3D 20.0 mL Similarly, the concentration of HSO; in Trial 1 is calculated thus: 0.010 M x 2.0 mL diluted [HSO, ] =0.0010 M HSO, 20.0 mLhow we can calculate the actual dissolved Oxygen concentration (cL) in oxygen transfer rate (OTR) formula .whenwe have cL than we can calculate the KLa value we find OTR from graph slope . cS =468/(31.6+T) T= 23 KLa = OTR/(cL- cS) cS = oxygen saturation concentration time(h) Dissolved oxygen(mg/l) 3.264 4.326 3.2818 3.697 3.29537 3.674 3.31445 3.268 3.33385 2.858 3.35218 2.475 3.37633 1.994 3.42174 1.15 3.4376 0.89 3.48951 0.249 3.54265 0.028
- Opioid dependence is described in the Australian Medicines Handbook as a chronic, frequently relapsing illness. One approach to managing opioid dependence is opioid substitution therapy (opioid maintenance therapy).

- You are interested to know the Q10 value for mean heart rate (# of beats/10 sec) for a species of crab for the temperature interval of 25°C - 35°C. To find this value, you collect data for these six temperatures and calculate mean heart rate (# of beats/10 sec) for each temperature. Here is the data: 10°C 15°C 20°C 25°C 30°C 35°C Mean Heart Rate (# 23.67 23.89 24.33 27 35.89 37.78 beats/10 sec) What is the Q1o value for heart rate (# of beats/10 seconds) for the temperature interval of 25°C - 35°C? Round your answer to two decimal places.You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.aining Time: 30 minutes, 45 seconds. Question Completion Status: 10 36 20 30 40 37 38 39 Give the product. 50 40 a C 41 47 OH T'H You H a "OH 8 1.BH3 2.
