Is AlCl3 a Lewis acid or base? Aluminum chloride (AlCl3) is a Lewis acid because the aluminum atom has an open valence shell. When aluminum chloride is under discussion it is called a Lewis acid or an electrophile. Is Oh Lewis acid or base? A Lewis base is any substance, such as the OH- ion, […]

Is the Schrodinger equation second order? In non-relativistic quantum mechanics, we have Schrödinger’s equation, which is first-order. But not every quantum particle is a fermion, and, AFAIK relativistic non-fermion particles obey the Klein-Gordon equation, which is second-order! Is the Schrodinger equation true? Consider the Schrödinger equation, which allows you to compute the “wave function” of […]

Can an electric field be infinite? 3 Answers. So there is no infinity. In two dimensions (or in one), the electric field falls off only like 1r so the potential energy is infinite, and objects thrown apart get infinite speed in the analogous two-dimensional situation. Does electric field increase with distance? Electric field strength is […]

Is coal a energy? Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. What emerging technologies will make coal safer? Low-NOx burners allow coal-fired plants to reduce nitrogen oxide emissions by […]

What are the 8 steps in scientific method? That procedure is commonly called the scientific method and consists of the following eight steps: observation, asking a question, gathering information, forming a hypothesis, testing the hypothesis, making conclusions, reporting, and evaluating. How do you design an experiment to test a hypothesis? Experimental design means creating a […]

What are the types of GPS? Types of GPS Tracking Devices Personal or Wearable GPS Trackers. This type is often the size of a wristwatch and is used by hikers or hunters in case of an emergency. Vehicles and Equipment. These are slightly larger and are typically used for boats, trailers, cars, or semi-trucks. Plug […]

Can we still recover lost Biodiversities? Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area. How does an ecosystem be able to recover from any disturbances? The major mechanisms of recovery in such ecosystems are primary and secondary succession. […]

Does the brain sit in fluid? Being surrounded by CSF helps the brain float inside the skull, like a buoy in water. Because the brain is surrounded by fluid, it floats like it weighs only 2% of what it really does. If the brain did not have CSF to float in, it would sit on […]

Do inductors go bad? Inductor Failures Inductors often fail open due to corrosion or bad internal solder joints or the inductors fail shorted due to electrical overstress, bad magnet wire insulation, or potting issues. Some images of common inductor failures are shown below. How do you know if an inductor is bad? The inductor should […]

What are the different levels of a food pyramid called? There are six categories in the Food Pyramid: the bread, cereal, rice, and pasta group (grains), the fruit group, the vegetable group, the meat, poultry, fish, dry beans, eggs, and nuts group (protein), the milk, yogurt, and cheese group (dairy), and the fats, oils, and […]
