please help with no 3,4,5 and 6 Thanks 1. What is standard error? Measure of statistical accuracy of an estimate, equal to the standard deviation of the theorental distribution of a large populanon of such estimates 2. What calculation is used to describe the variation in measurements. 3. In experiment 3.2. You will be measuring out 40ml of volume. How many times will you measure 40 ml? 4. What is the difference for each time you measure out 40ml? In...
question one question two Aspirin lab (10 points) 5. a) Spectroscopy is being used to determine the concentration of aspirin in an unknown sample. The absorbance spectrum of the highest concentration standard [Fe3+, SA) prepared is given below. What wavelength should be used to create the calibration curve for the experiment? Explain your reasoning. 0.14 Absorbance 0.02 250 300 450 500 350 400 Wavelength (nm) Wavelength Explain your reason briefly. b) In this experiment an aspirin tablet was placed in...

All of the solutions used today can be washed down the sink with water. Solid waste should be thrown in the bin. Experimental This experiment is to be carried out individually NOTE: Failure to follow the correct procedures as explained in Skill 4 will result in wildly inaccurate results. The notes below do NOT give a full description of the techniques. 0 2 Standardisation of 0.1 M sodium hydroxide with the primary standard potassium hydrogenphthalate Part A (Al) In a...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
