Common Name: Pearl Scientific Name: Calcium Carbonate Formula: CaCO3 Fundamental particles: Pearls are comprised of a positive Calcium ion (Ca+) and a negative Carbonate polyatomic ion (CO3+) Usage: Jewelry Properties: Pearls are good jewelry because they are hard and lustrous. Pearls are hard because of the strong Intermolecular forces created between the Calcium and the Carbonate ions. The pearls luster is dependent on the amount of nacre excreted. The Oyster produces nacre when

this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy. This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules from an area of higher concentration

the ideas of cultural diffusion. Cultural diffusion is the exchanging and adaptation of ideas amongst people of the world. It is a constant force that allows us to accept and modify an idea to mold into our own world. Throughout great civilizations of history‚ the idea of cultural diffusion has spread and continues to spread in present time. This idea usually enforces contact between neighboring strangers. McNeill addresses the specific issue of how cultural diffusion came to shape new civilizations

Hands On Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B. Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue

| Distillation is defined as: `Distillation is based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points.Therefore‚ when this vapor is cooled and condensed‚ the condensate will contain more volatile components. At the same time‚ the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently.Although many people have a fair idea what “distillation” means‚ the
