Nuclear reactions are how much more energetic than chemical reactions? A Option A: 10 billion times B Option B: 10 thousand times C Option C: 10 times D Option D: 10 million times
Homework Answers
In Nuclear reaction proton and neutron react inside nucleus.As a result they produce huge amount of energy.While in chemical reaction electron react outside the atom and there is very low production of energy.In general Nuclear reaction are 10 million times energetic than ordinary chemical reaction.

Astronomers now think that there is a black hole with more than 4 million times the mass of our Sun at the center of our Galaxy? Roughly how large would the event horizon of such a supermassive black hole be? A. the size of our Moon B. about 4 light years across C. about 17 times the size of the Sun D. about the size of an atom (so much mass really compresses the event horizon) E. we can’t answer...

Il Review | Constants Periodic Table Unlike chemical reactions, for which mass is conserved, nuclear reactions result in slight changes in mass. When mass is lost, it becomes energy according to the equation Natural gas (mainly CH4) is used in many power plants to generate electrical power utilizing combustion reactions. Uranium-235 is used to generate power utilizing nuclear fission. Fusion reactions involving hydrogen-1 are under investigation as a future source of electrical power. AE=Amục where AE is the energy in...
