What is the smallest unit of the universe? The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across. What is the farthest from Earth? Real-time distance and velocity data is provided by NASA and JPL. At a distance of 152.6 AU (22.8 billion km; 14.2 billion […]

How many molecular orbitals will have an N value of 2? Explanation: The atomic orbitals with an n value of 2 are the 2s orbital and the three 2p orbitals. When these four orbitals from one atom interact with four orbitals from another atom, they generate 8 molecular orbitals, half of which will be bonding […]

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 mass number and charge of the emitted positron? This positron can be called a beta plus (β+) particle – this process is known as positron emission. A positron is the antimatter version of an electron. It has the same relative mass of zero, so its mass number is zero, but a +1 […]

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 […]

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 […]

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 […]

What causes light beams to be parallel? A narrower beam of laser light spreads out more quickly than a wider beam. Only an infinitely wide beam (a plane wave) does not spread out, and therefore has parallel waves. Divergence is observed by shining a laser light on a wall and then seeing the spot grow […]

How is DPU calculated? The formula is the total number of defects divided by the total number of units sampled or inspected. Therefore; the DPU in this example is equal to seven divided by fifty. The answer is 0.14. What is the formula for DPMO? It is defined as the ratio of the number of […]

Why is one ear canal bigger than the other? The most common reason is that your ear canals are exact copies of each other. Most ears do not match their partners. One can be bigger than the other. One can have a different shape. Is Microtia inherited? Although most occurrences of microtia aren’t hereditary, in […]
