what happens to atoms during a chemical reaction?

Atoms do not take part in a chemical reation

they are destroyed

they are rearraned

they change into other atoms.

if there are 2 atoms of oxygen and 4 atoms of hydrogen before a reaction what will be true after the reaction?


If there are 2 atoms of oxygen and 4 atoms of hydrogen after the reation

there will be 6 atoms after the reaction,but none of them will be hydrogen or oxygen

There could ne any number of atoms of any element after the reation

There could be any number of oxygen atoms and any number of hydgen atoms after the reation

In Einstein's theory of relativity, he talks about gravity bending space so that objects are pulled towards other massive objects.

If a force like gravity "bends" space, then would it be likely that a force like electrical charge would also "bend" space? After all, they are both "forces" and they both work on other objects at distance. They also both have strengths related to the inverse of the distance from the object creating the force.

However, an electric charge doesn't effect everything around it in the same way that gravity does. The electric charge only attracts or repels other charged objects. So, how could the electric force be bending space? Could it just be "bending" space for some objects but not others?

It seems like, in my opinion, that if you want to be able to find a link between the two forces, you would need to get rid of the "bending of space" idea. Have people working on the "Grand Unified Theory" come up with any ideas on this subject?

Isn't that a logical use of the space program? Some type of "enrichment" activity for an energy source, provided it is stable enough to transport.
