The image shows hydrogen's emission and absorption spectrum. This is compatible with which kind of model? (1 point)
O wave model because the spectrum is a continuum.
O wave model because the lines in the emission spectrum continue in the absorption spectrum.
particle model because the atom's electron absorbs and emits energy in discrete wavelengths.
O particle model because only this model can explain energy transfer.

its c its is a mixture of gases

when it gains or loses electrons

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.
