Most water moderated reactors use yellowcake powder: a uranium oxide enriched to 3% uranium-235. A few reactors use metallic uranium, sometimes enriched past 20%. Some experimental reactors use plutonium or mixed uranium & plutonium.

What is true is true regarding hydrogen fuel cells and hydrogen fuel cells and hydrogen fusion?

More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX


Is a nuclear fusion nonrenewable?

yes, once the fuel is consumed the reaction ends.


Does combustion fuel the sun?

no combustion dose not fuel the sun but the sun is fueled by a nuclear reaction known as fusion.

Does fusion reaction occur in an atomic bomb?

Yes, fusion reactions occur in a hydrogen bomb, which is a type of nuclear bomb. The high temperatures and pressures generated by the fission reaction in the bomb can trigger fusion reactions between hydrogen isotopes. This fusion reaction releases a large amount of energy, contributing to the destructive power of the bomb.


How does the sun use up its fuel?

All stars- including our sun- are an ongoing nuclear fusion reaction- hydrogen is fused into helium. The hydrogen is consumed in that reaction.


Which of the following is true regarding hydrogen fuel cells and hydrogen fusion?

The amount of mass that "disappears" in the fusion of two hydrogen atoms is more than the amount of mass that "disappears" when two atoms are used in a fuel cell.the amount of mass that dissapears.........ect


How stars grow old and die?

When stars "age", they spend their fuel source in a nuclear reaction (usually nuclear fusion).


Do stars give off light as a part of a nuclear fusion reaction in which helium atoms are split into hydrogen atoms?

No. In a fusion reaction, a heavier element is made of a lighter pair by "gluing" them together in a fusion reaction. When we split an atom, that's called atom splitting, or sometimes fission, not fusion. They are opposites. Stars give off light, but the primary fuel in their fusion engines is hydrogen, which they convert into helium. As the hydrogen burns out, the star begins making helium into carbon.


What waste product does a fusion reaction generate?

A fusion reaction generates helium as a waste product.
