Review Sheet 1 Results 1. Describe two variables that affect the rate of diffusion. Your answer: Two variables that affect the rate of diffusion are the MWCO membrane and the solute concentration. Increasing the membrane size and solute concentration will also increase the average diffusion rate. Decreasing the membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane

To calibrate a 50 mL measuring cylinder INTRODUCTION The purpose of this experiment is to study the relationship of several types of volumetric glassware and the accuracy of measuring the volumes of liquids very precisely in quantitative laboratory work. The accuracy of the measurement the volumes is the degree of closeness of measurements of a quantity’s actual volumes while the precision of the volumes is the degree to which repeated measurements under unchanged conditions show the same

Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts.

Implementing Change in the Clinical Skills Laboratory For the last several years‚ the nursing shortage has continued to influence the nursing faculty and the acceptance of nursing students. According to Walrath and Belcher (2006) 32‚617 qualified applicants were denied entrance into nursing schools in 2005 because of the shortage of qualified nursing faculty. The schools of nursing have continued to increase enrollment‚ yet the faculty and infrastructure has been unable to accommodate the demand

FOUNDATION IN SCIENCE INTRODUCTION TO PRACTICAL ORGANIC CHEMISTRY – MAKING AND PURIFYING ORGANIC COMPOUNDS Stage 1 – Deciding how much reagent to use Most organic reactions do not go to completion; most reach an equilibrium position with significant quantities of reactants still remaining. In addition‚ separating the desired product from the rest of the reaction mixture‚ and then purifying it‚ will result in the loss of more of the product. The amount of product obtained expressed as a percentage
