Massive amounts of destructive energy are released when a nuclear fission bomb explodes. where does that energy come from?

a)

compounds are created, releasing chemical energy.

b)

a chain reaction occurs when uranium atoms split, releasing nuclear energy.

c)

bonds between atoms break, releasing chemical energy.

d)

hydrogen atoms fuse together into helium, releasing nuclear energy.

I say it's  chain reaction occurs when uranium atoms split, releasing nuclear energy.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

the components of a vector are the parts of the vectors that are to each other.
