How much energy is released for alpha decay of ^236U?
1 U-236 ----> 1 Th-232 + 1 He-4 + mass lost mass lost = 236.045637 - 232.038124 - 4.002604 = 0.004909 amu 0.004909 amu x (1.660x10^-27 kg / 1 amu) = 8.149x10^-30 kg E = mc^2 = 8.149x10^-30 kg x (2.998x10^8 m/s)^2 = 7.324x10^-13 kJ / atom
How much energy is released when 10 kg of uranium 235 is converted to energy?
1 kg of Uranium-235 contains 1000 235.044 × 6.023 × 10 23 = 2.562 × 10 24 atoms.The energy released during each U-235 fission reaction = 202.5MeV.Assuming all the U-235 atoms undergo fission, the total energy released by the fission is.
How much energy is released when 50.5 of water freezes?
the standard enthapy of fusion for water is 6.01 kJ/mol 50.5 grams, moles, pounds or ? email me by clicking on my avatar =============================== for 50.5 moles of water @ 6.01 kJ.mol = 304 kJ released for 50.5 grams @ 6.01 kJ / 18 grams = 16.9 kJ released
2.16 moles of the fuel combusts, 1,670 kJ of energy is released. What is the delta Hrxn?
In a reaction of a potential new fuel, it is found that when 2.16 moles of the fuel combusts, 1,670 kJ of energy is released. What is the delta Hrxn for the combustion of the fuel in units of kJ/mol.
How much energy is released whenever an electron is released by an atom?
Energy isnt released but it is absorbed when an electron is released from an atom. The energy of a particular orbit for hydrogen and hydrogen like species(that is having a single electron in its atom) is given as En=-(2pi^2*m*e^4*z^2)/((4pi*epsilon0)^2*n^2*h^2). which is about -2.178*10^-18*z^2/n^2 where z is the number of protons in its nucleus or atomic number and n is the princibal shell number so when an electron goes from one shell to another it releases an energy equal to the difference of energies of the two shells the equation for change in orbital becomes -2.178*10^-18*z^2((1/n1^2)-(1/n2^2)) where n1 is the initial shell and n2 is the final shell for escape from an atom an electron must travel to the infinith shell thus n1 is the initial shell number and will be equal to 1 and n2 will be infinity thus the energy required becomes -2.178*10^-18*z^2J/atom for hydrogen z is 1 for helium z is 2 and so on so you can calculate the energy released which is also equal to the energy of that shell and that expressed by the first equation. Just remember that if it is 2.178*10^-18 it is J/atom and if measured in Kj/mole it is -1312kj/mole
How much energy is released when 1 gram of mass is lost during the nuclear reaction?
According to the famous equation of mass-energy conversion:E=mC^2Where,E= energy released or absorbed during reactionm= mass of particleC= speed of light or photons= 3*10^8 m/secSo, using this formulae,Energy released= [{1*10^(-3)} * (3* 10^8)^2] joules = 9*10^13 joules = 90 TJ.Basically this energy-mass conversion equation is used in such kind of calculations throughout.Hope this might answer your doubts.Thanks and regards.
What is energy release during respiration?
Respiration is a biochemical process where oxygen is used to breakdown molecules and release energy(ATP). This energy is utilized for the cell growth.
