Keeping in mind the assays done in Lab 1/2, (a) how could you design a colorimetric method to measure alpha-amylase activity? (b) What would you use as a control? (c) At what wavelength should the spectrophotometer be set? (d) Sketch a graph like Plot 1 (from this lab) to represent the amylase activity you would observe using your method. You want to know whether alpha-amylase is more active in the stomach (pH 2) or the intestines (pH 7). (a) How...

Question 1. You will inject air into a sealed reaction bottle at room temperature and measure the pressure change within the bottle. Suppose 25.0 mL of air at an initial temperature of 20.5 degrees Celsius and an initial pressure of 1.010 atm was injected into a reaction bottle that contained 30.0 mL of water. A. How many moles of air are contained in the syringe? B. Pretend the gas you injected into the vessel all dissolved into the 30.0 mL...
