When testing the effect of molecular weight on diffusion, the hydrochloric acid and ammonia molecules were placed at different ends of a sealed tube. The ammonium chloride that formed when the molecules diffused towards each other and met was closer to the ammonia end of the tube. TRUE OR FALSE? Diffusion continues to occur until there is an equal concentration of particles on both sides of a semi-permeable membrane. TRUE OR FALSE? Diffusion is the spontaneous net movement of particles...

3. True/False. If False, correct the underlined word. [4pts] Capillary Action is the diffusion of water through a semipermeable membrane from a high water concentration to a low water concentration. a) b) Cohesion is a property of water. It occurs when water molecules bind to other water molecules forming Hydrogen bonds

A concentration gradient affects the direction that solutes diffusion. Describe how molecules move with respect to the concentration. How does size affect the rate of diffusion? Does polarity affect the rate of diffusion? Explain your answer. If a piece of celery is placed in a glass of pure water, are the celery cells hypertonic, hypotonic or isotonic compared to the water? In which direction will water move? What is the water potential of pure water? Why don’t red blood cells...
