  Burning of Magnesium Brief Description: When a piece of magnesium ribbon is ignited, light and heat are produced. Purpose/Goal: A quick demonstration which illustrates the concept of an exothermic reaction, as well as one that produces light energy. Explanation of Experiment: The oxidation or combustion of magnesium in air has long been used as a source of intense light in photography and for other photochemical reactions. The energy released in this combustion occurs as the magnesium reacts with oxygen in the air according to the equation: 2 Mg (s) + O2 (g) → 2 MgO (s) The heat of formation of magnesium oxide is -601.83 kJ/mol. When magnesium burns, approximately 10% of the energy of combustion occurs as light, a value unapproached among known transformations of energy used in the production of light. Materials Preparation: 6-8 cm magnesium ribbon sanded to remove oxide coating Bunsen burner, charcoal grill lighter or similar Tongs Presentation: Light the burner and adjust the f...

Thiomargarita magnifica is a unique and fascinating microbe that belongs to the group of bacteria known as the sulfur bacteria. It is a large, spherical bacterium that can reach up to 0.75 mm in diameter, making it visible to the naked eye. Thiomargarita magnifica is unique in that it is the largest known bacterium and can be found in marine environments all over the world, from the deep sea to shallow coastal waters. The name "Thiomargarita magnifica" is derived from the Greek words "thio" meaning sulfur, "margarita" meaning pearl, and "magnifica" meaning magnificent. The name is fitting, as Thiomargarita magnifica forms large, pearl-like aggregates in marine sediments that are visible to the naked eye. These aggregates are made up of many individual cells, which are held together by a mucus-like substance. The cells of Thiomargarita magnifica are not tightly packed together, but instead are loosely arranged, leaving spaces between the cells. On...
