Huge explosion that forms a nebula?
A supernova
What elements are formed during a nova or supernova?
It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event. These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star. In this catastrophic event, the iron and silicon (and any other lighter elements) in the star are super compressed. The already hot conditions are made even hotter, and the available energy is sufficient to drive the fusion reactions that create the trans-iron elements.All the fusion reactions up through those that create iron are exothermic, and that means they release energy. The fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements.See periodic table (iron is number 26).See related link.
How is it the super novas after the big bang didn't form black holes but rather elements?
There are two explanations. First, when a massive star forms a black hole, usually only a small portion of the star's mass actually goes into the black hole. Most of the rest is blasted away in a supernova, enriching the surrounding space with heavier elements. Second, there are also pair-instability supernovae. Such supernovae occur in extremely massive stars with a very low content of heavier elements, which likely existed in the early universe. Pair-instability supernovae will blow away the entire star, leaving behind no black hole or neutron star remnant.
Can supernova occur in the same star more than once?
Remember that Supernovas are great contributors to interstellar material that forms new stars. The star which explodes to supernova will leave either a pulsar or a black hole depending on its mass. Part of the supernova will scatter into space.
What forms from the leftover material from a supernova and it may contain as much as three times the mass of the sun?
Neutron star
What forms when stars explode?
A supernova, resulting in either a neutron star or black hole. Also may heavy elements are blown out of the star during the explosion.
Huge explosion that forms a nebula?

What forms leftover material from a supernova?
neutron stars
Which elements are in the human body?
There are many, many elements in the human body, the most common of which is Carbon, as we are carbon based life forms. There is also a lot of oxygen present in the form of oxides, and other elements such as iron in haemoglobin (present in blood) and phosphorus in DNA.
Is the phrase after a supernova an adverb or an adjective phrase?
It is an adverb phrase, although in forms such as "The period after a supernova is marked by stellar collapse" it seems to be an adjective phrase.
What are exploding stars?
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.

What are the present forms of the verb to have?
The present forms of the verb "to have" are: I have You have He/she/it has We have They have
An explosion of a star?
When a star explodes, it is referred to as a nova. If the star is large enough, it will create a super nova. And if the star is dense enough, it does not explode, but instead collapses on itself and forms a black hole
Are the elements in the compound salt dangerous?
The elements which make up table salt, sodium and chlorine, are dangerous in their elemental forms. However, their ions (which are present in table salt) are much less harmful.
What is the present perfect tense for pass?
The present perfect forms are have passed and has passed.Examples:We have passed this way before. (plural subject)He has passed this way before. (singular subject)
