A supernova occurs when a star exhausts its nuclear fuel, typically hydrogen and helium, leading to a collapse under its own gravity. In the case of a massive star (Type II supernova), the core collapses after fusing heavier elements up to iron, which cannot produce energy through fusion. For a white dwarf (Type Ia supernova), it accumulates material from a companion star until it reaches a critical mass and undergoes a thermonuclear explosion. Thus, the "fuel" for a supernova is the remnants of nuclear fusion processes in a star's life cycle.
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
Yes, a red giant star can undergo a supernova explosion at the end of its life cycle. This occurs when the star has exhausted its nuclear fuel and can no longer support itself against gravity, leading to a dramatic collapse and subsequent explosion.
The range of masses for a supernova typically falls between about 8 to 50 times the mass of the sun. When a star that massive runs out of nuclear fuel, it undergoes a catastrophic collapse resulting in a supernova explosion. Smaller stars may end their lives in a different type of explosion called a nova.
Our Sun is currently a main sequence star. It is not a supernova, as supernovae are massive explosions that occur at the end of a star's life cycle, and it is not a white dwarf, which is a type of star that has exhausted its nuclear fuel and collapsed to a very dense state.
A supernova occurs in a star's lifecycle when it runs out of fuel and its core collapses, causing a massive explosion.

A nebula contains stars and other matter; a supernova is just a large enough nova, or star that explodes at the end of its life cycle due to spent fuel

Dangerous. Novas, or supernovas. Tycho Brahe coined the phrase "nova stellarum" when a "new star" appeared in the night sky. We now know that he was observing a supernova, the death throes of a very massive star.

They explode as a supernova/hypernova to form a planetary nebula/black hole.
