Einstein, Albert mass energy equation

Ever since Albert Einstein devised his famous equation, E = mc, we have known that mass and energy are interconvertible. In Einstein s equation, E is energy in kg m /s (J), m is the mass in kg, and c is the square of the speed of light. 

In your study of chemical reactions, you learned that mass is conserved. For most practical situations this is true—but, in the strictest sense, it is not. It has been discovered that energy and mass can be converted into each other. Mass and energy are related by Albert Einstein s most famous equation. 

In the early 1900s, Albert Einstein developed a famous equation relating mass and energy in nuclear reactions. Use this equation to explain why nuclear reactions release very large amounts of energy. 

In 1905, Einstein s (Albert Einstein, 1879-1955) special theory of relativity connected the property of mass with energy with his now infamous equation E = mc. This mass-energy... 

Albert Einstein s most famous equation relates mass and energy. 

It can be seen that the mass numbers on either side of the equation add up to the same number, 238, and that 92 protons are accounted for in the equation s product and reactant sides. This is a balanced nuclear equation. Actually, some mass is converted into energy, but the amount of mass is very small. From Albert Einstein s equation, E = me2, very little mass, m, is needed to produce a tremendous amount of energy, E, because c is the speed of light, 3 x 108 m/sec. This energy was evidenced when an atomic bomb was exploded over Hiroshima, Japan, during World War II. The fuel for that bomb was uranium-235. 

In 1905, Albert Einstein (1879-1955) published his theory that the mass of a sample of matter is increased as the energy of the sample is increased. For example, a baseball in motion has a very slightly greater mass than the same baseball at rest. The difference in mass is given by the famous equation... 

We have seen that light can be treated as particles (photons) with an energy equal to hv. The energy of the photon can also be obtained from Albert Einstein s famous equation relating mass and energy ... 

Today, because of Albert Einstein s theory of relativity, we know that mass is not strictly conserved. Einstein showed that mass and energy are equivalent, as stated in his famous equation E = mc where E = energy, m = change in mass, and c = speed of light. Changes in mass are appreciable In nuclear reactions. However, In ordinary chemical reactions the changes are so miniscule that they can be Ignored. 

The theory proposed by Democritus—that the atom is indestructible—dominated science for centuries until Albert Einstein published his equation in 1905> suggesting mass could be converted into energy. Until then the world s most prominent scientists all insisted the atom could not be broken apart. All things considered, Isaac Newton wrote in 1704, it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, moveable particles [and] these primitive particles, being solids, are incomparably harder than any porous bodies compounded of them even so very hard, as never to wear or break into pieces. ... 

Starting materials. The missing mass has been converted into an enormous amount of energy, consistent with the famous equation derived by Albert Einstein.
