That depends on HOW massive. From about 2 times the mass of the Sun to about 5 times the mass of the Sun, the dying star will explode and crush the core into a neutron star. More than about 5 solar masses, and the result will probably be a black hole.
However, there's a LOT that we don't yet understand about stellar evolution and stellar dynamics.
Massive stars (around 8 or so sun masses) will ultimately end up as neutron stars. Stars heavier than 10 solar masses will turn into black holes.
Iron builds up, and eventually the star does not have enough fuel left to counter the compression caused by gravity. It then collapses, and the core becomes a neutron star or a black hole.
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
Most stars usually die out
Less massive stars end up as white dwarfs. More massive stars end up as a supernova or a neutron star or for the really massive stars...as a black hole. As a star ends its time in the main sequence it either becomes a Red Giant and end its life as a White Dwarf or becomes a White Super Giant and ends its life in an explosion (supernova) and if it's really dense it becomes a neutron star or a black hole as mentioned above.
Most stars end up as white dwarfs. A few become neutron stars. Even fewer become black holes.
No, all a black dwarf is is a white dwarf that has cooled, it's mostly carbon and oxygen and nitrogen. A black hole forms when the gravity of a collapsing star is able to overcome all opposing forces.

its called a super nova.
As stars burn, they shed matter, becoming less massive slowly throughout their life cycle. This reduction in mass necessarily lessens their gravity, causing the stars' diameter to increase. So, many end-stage stars will be huge and bloated. Massive red giant stars are examples of this.
No. Supernovas are cataclysmic eruptions from massive stars that have come to the end of their lives. See related questions
Its mass - the larger its mass the shorter its life.The smallest and least massive stars can last for trillions of years, whereas a massive star may end its life in millions of years.
