Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

Examining Diffusion and Osmosis Introduction: Purpose: 1. To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring in dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random‚ constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other

Factors Affecting Diffusion How does temperature affect diffusion? What is Diffusion? Definition 1: Diffusion is a process where by molecules move from an area of high concentration area to an area of low concentration. Definition 2: Diffusion is an evidence for moving particles. The spreading out of a gas is called diffusion and it takes place in haphazard and random way. Gases diffuse because the particles collide with other particles and bounce of in all directions. For example when

organization will determine your level of project management authority as well as the availability of the resources that you will work with. Organization structure refers to how an organization decides to organize itself in order to operate the business activities. Organization structure is influenced by the culture of the organization. Bro Uttal (1983) coined organization culture as a system of shared values (what is important) and beliefs (how things work) that interact with a company’s people‚ organization

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport‚ without requiring bulk motion. Thus‚ diffusion should not be confused with convection‚ or advections‚ which are other transport mechanisms that utilize bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach
