What are the relative rates of diffusion between CH4 and N2?
How do the following effect diffusion rates: -Total surface area -Diffusion distance -Concentration gradient -Physical and chemical properties of diffusing particles, carrier material (solid/liquid) -Barrier between the compartments
A gas mixture contains 6.6g of N2, 6g of H2, and 29.4g of CH4. what is the mole fraction of H2 in the mixture? i keep getting 0.08879 but it says i an wrong. TIA
•Differentiate between passive(simple) diffusion & passive facilitated diffusion. What is the role of proteins in facilitated diffusion? • what is the role of electrical gradient in membrane potential? • predict how membrane potential can change depending on the movement of positive charges in or out of the cell, starting with -70 mV
