False. A brown dwarf is a failed star that cannot sustain nuclear fusion. When a star explodes it will leav behind either a neutron star or a black hole depending on its mass.
A brown dwarf.
The size should be about the same. The mass, of course, is greater.
supernova
The basic requisite is that enough mass gets together. This can happen with a large star if, after it explodes as a supernova, enough residual mass remains to go beyond the limit of a white dwarf, and of a neutron star. Yet there is also another possibility: a star may end up first as a white dwarf or as a neutron star, but it may eventually receive enough infalling matter to become a black hole.The basic requisite is that enough mass gets together.

Supervernova
Eris is thought to be the largest of the five dwarf planets.
The same size as the white dwarf it was. See related question.
Potassium metal is a metal that explodes when put in cold water. It causes a chemical reaction which results in a large explosion.
When a Red Giant or any large star explodes, it is called a super nova, creating a either a black hole or a neutron (pulsar) star.
A white dwarf consists of the core of the large star it once was.
Large False Serotine was created in 1905.
False. It is a large statue.
