Does hydrogen implode or explode

Answer 1

I'm assuming you are referring to the hydrogen combustion reaction shown below:

2 H2(g) + O2(g) -> 2 H2O(g)

Since three moles of gas are converted to two moles of gas, the pressure of the system deceases causing an implosion.

Answer 2

Planets don't tend to explode, they maybe ripped apart through a huge collision with another large body, but such a collision would be extremely rare in a developed solar system. A planet maybe destroyed through large exotic weaponry, such as a deathstar or gravitational bomb, but this is the stuff of Science Fiction.

Answer 3

No, they are very different things. Stars are like our sun, they are massive balls of hydrogen (mainly) where nuclear fusion at the core gives off vast amounts of energy. Planets are much smaller bodies of gas and/or rock.

Answer 4

yes, if the core of the earth is hot and we keep using green house gases and not predecting our earth it will one day, not now, but soon, maybe blow up.

Answer 5

Only in the comic books. Or in the movies. Never in real life.

Answer 6

No, there is no reason for them to do so.

Answer 7

No.
