What is the atomic mass of Mg2+? 24.305 g/mol What is the atomic number of Mg2 +? 12 Why is magnesium ion Mg2+? Magnesium, Mg It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed. A magnesium ion has the same electronic structure as a […]
What is the 5 era?
What is the 5 era? The book divides the timeline of the universe into five eras: the primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the […]
What is the mass number and charge of the emitted positron?
What is the purpose of dark matter?
What is the purpose of dark matter? [+] Dark matter is the most mysterious, non-interacting substance in the Universe. Its gravitational effects are necessary to explain the rotation of galaxies, the motions of clusters, and the largest scale-structure in the entire Universe. Can we see dark matter? Although we cannot see dark matter and we […]
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down?
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down? Another way to say this is that if the acceleration has the same sign as the velocity, the object will be speeding up. And if the acceleration has the opposite sign as the velocity, the object will […]
What frequencies are dangerous?
What frequencies are dangerous? The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the RF energy is absorbed most efficiently when the whole body is exposed. For devices that only expose part of the body, such as mobile phones, different exposure limits are specified. What is the range […]
How much power does a 5kW solar system produce per day?
How much power does a 5kW solar system produce per day? 5kW Solar System Details: Produces 5,000 watts of DC (direct current) power. Requires up to 400 square feet of space to produce an estimated 350 to 850 kWh (kilowatt hours) of AC (alternating current) power monthly. Is 5 kW solar enough? On average, a […]
How does experience affect our perception?
How does experience affect our perception? Past Experiences and Education What you perceive is strongly influenced by your past experience, education, culture, values and other factors. All these influences predispose you to pay particular attention to certain information and to organize and interpret the information in certain ways. Has any of your past experiences affect […]
Is heat equal to change in enthalpy?
Is heat equal to change in enthalpy? At constant volume, the heat of reaction is equal to the change in the internal energy of the system. At constant pressure, the heat of reaction is equal to the enthalpy change of the system. What is flow and non flow process in thermodynamics? Non flow process: It […]
How important is the lithosphere?
How important is the lithosphere? The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. When the biosphere interacts with the lithosphere, organic compounds can become buried in the crust, and dug up as oil, coal or natural gas that we can use […]
