Oxygen
the gasses were dissolved in the lava until the pressure was released near the surface.
The gas giants have no volcanoes; they are composed entirely or almost entirely of gas, so there is nothing to erupt. However, it should be noted that some of the satellites of the gas giants do have volcanoes.
Gas is what gives volcanoes most of their power. One of the reasons this happens is because the gas keeps expanding.
Yes. Volcanoes are very dangerous. Depending on the type of activity volcanoes can produce toxic gasses, lava flows, heavy toxic ash, mudflows called lahars, and fast moving avalanches of hot ash, rock, and gas called pyroclastic flows.
The smelly gas that often accompanies active volcanoes is known as fumarole gas. This has the same odor as rotten egg.

No. Neptune is a gas planet with no solid surface. It cannot have volcanoes.
The amount of gas and the pressure in the volcanoes.
No, but its moon, Titan, may have volcanoes.
