difference in concentration of the ion or molecule between the sides of the membrane 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the 20 MWCO membrane because it does not ionize. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well

Anatomy & Physiology I Lab Chemical and Physical Processes of Digestion Introduction: In this lab‚ we will see how different chemical processes occur as we observe how different enzymes digest different substrates and produce subunits. Key Terms: (found in bold in Lab Manual) Please define all bold terms in your own words: Enzymes- Large protein molecules made by your body cells. Catalyst- Without becoming part of the substance it will change the rate of the chemical reaction. Hydrolyses-

Shelby Brown 8/28/10 Physical and chemical changes lab essay Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s

Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations
