What is the process of nitrification? Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines. What are the steps of nitrification? In general, the nitrogen […]

When galaxies are moving away from us what light color do we see? Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If […]

What are the characteristics of a warm front? Warm fronts are typically characterized by a transition from southeasterly to southwesterly winds. Unlike cold fronts, winds along the front itself are generally light and variable. Warm fronts, as their name implies, are also characterized by a rise in temperature, but also humidity. When a weather front […]

What is the shape of gef2? trigonal planar What is Vsepr formula? The “AXE method” of electron counting is commonly used when applying the VSEPR theory. The electron pairs around a central atom are represented by a formula AXnEm, where A represents the central atom and always has an implied subscript one. Each E represents […]

Which one is the best example of law of conservation of mass? The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it […]

What are the 3 factors that sustain life on Earth? What are the 3 interconnected factors that sustain life on earth? Solar energy, nutrient cycles, and gravity. What are the features that make life possible on Earth? What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful […]
