One atom of Deuterium weighs 2.013553AMU. One atom of Helium weighs 4.002602AMU. In nuclear fusion, the process which powers the Sun and all other stars, 2 atoms of Deuterium are combined to form 1 atom of helium. Calculate the energy released by one such combination. (1AMU = 1.660539x10-27kg)
I really don't know what to do for this question. Even a formula would help me. thanks
Well, I gave you the necessary equation but perhaps I should elaborate.
You were given very precise values for the masses of the two deuterium atoms and the one He atom.
Add the masses of two De atoms and subtract He atom.
That is mass that disappeared, violating the laws of classical physics (conservation of mass) and requiring the use of Einstein's equation relating mass and energy.
What is the chemically combined substance of a hydrogen atom and a helium atom. please help me because i really don't know this is confusing really please and thankyou Hydrogen atoms don't normally combine with helium atoms. In
Which statement correctly describes an atom of the element helium? A. An atom of helium has its valence electrons in it's first energy level. B. An atom of helium most similarly behaves like an atom of hydrogen since it is in the
A helium-4 atom falls from a height h into a tank of gaseous helium atoms at 300 K. What is h in meters if the temperature of the helium atoms remains at 300 K after the falling atom enters the tank? Details and assumptions The
An ionized helium atom has a mass of 6.6*10^-27kg and a speed of 4.4*10^5 m/s. The atom moves perpendicular to a 0.75-T magnetic field on a circular path of radius 0.012m. Determine whether the charge of the ionized helium atom is
Imagine that your car is powered by a fusion engine in which the following reaction occurs. 3*deuterium--->helium + hydrogen + neutron The masses are (2.0141 u), (4.0026 u), (1.0078 u) and (1.0087 u). The engine uses 8.1 10-6

Why is an alpha particle written as a helium (He) nucleus? A. An alpha particle has two protons and two neutrons; it is essentially the nucleus of a helium atom. B. Helium is a common element that is often present in small forms;
