What happened to the pregnant wife in Chernobyl? One of the main characters in HBO’s miniseries “Chernobyl,” the pregnant wife of a young firefighter, still lives in Ukraine. The real-life Lyudmilla Ignatenko recently told the BBC that reporters have accused her of killing her unborn child. Why did Chernobyl cause birth defects? A 2010 study […]
What happens when you mix sodium and chlorine?
What happens when you mix sodium and chlorine? If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light […]
What are 3 differences between ionic and covalent bonds?
What are 3 differences between ionic and covalent bonds? An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. Ionic bonds form between a metal and a nonmetal. Covalent […]
Is inhaling helium bad?
Is inhaling helium bad? The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in pure helium can cause death by asphyxiation in just minutes. Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, […]
How can we determine the size of the Earth?
How can we determine the size of the Earth? It was generally agreed upon that measuring the size of Earth could be done by measuring the altitude of a star from two cities situated on the same meridian. Then, a difference expressed in degrees would be found. How is the Earth’s curvature measured? How could […]
Can you hear a radio wave?
Can you hear a radio wave? Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched). … Can teeth pick up radio signals? The electrical conductivity of […]
Where are water masses formed?
Where are water masses formed? Water masses are formed as the result of climatic effects in specific regions. Antarctic bottom water is an important water mass that forms on the Antarctic continental shelf as a cold, dense residual brine during the formation of sea ice. Which water mass is the saltiest in the world? That […]
How is charge transfer calculated?
How is charge transfer calculated? Measurements of charge transfer may be made either measuring the voltage developed across a capacitor to earth, instead of the resistor, or using a virtual earth charge measurement amplifier. Another approach is to integrate discharge current flow measurements over the duration of the discharge. Can you transfer battery power from […]
Why do electrons want to be stable?
Why do electrons want to be stable? A complete octet is very stable because all orbitals will be full. Atoms with greater stability have less energy, so a reaction that increases the stability of the atoms will release energy in the form of heat or light. A stable arrangement is attended when the atom is […]
What year will the sun explode?
What year will the sun explode? In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you. Is Sun getting weaker? […]
