They annihilate each other, releasing a relatively large quantity of energy, which can be calculated using the formula e=mc2, where e is the released energy in joules, m is the mass of the particles in kilograms, and c is the speed of light in metres per second
Nothing different than when matter enters, in fact there is no way to tell whether a black hole was formed from matter or antimatter.
Once inside the black hole, if matter and antimatter react to make energy, that energy can't escape the black hole either.
When a particle of matter meets a particle of antimatter, the collision results in the annihilation of both particles, with a release of energy as described by Einstein's famous e=mc^2 equation. In ideal conditions, it could be described as a near perfect conversion of matter to energy.
It depends how much. Less than a trillionth of a mg of antimatter could vaporise a human being. So, if you're talking about a lot of antimatter, we're talking about a MASSIVE explosion.
it explodes
This has some truth in it. When antimatter and matter collide, they change into energy, so the world could in theory be destroyed. Antimatter-matter collisions produce huge amounts of energy.
Yes, antimatter - as was recently produced at CERN.
Yes it is. This does not mean that it has the properties ascribed to it in any particular work of fiction (Star Trek's version is reasonably realistic, Green Lantern's version is hopelessly silly), but yes, something by that name does really exist. ************************************************************************* Antimatter is real. Some scientists believe that antimatter is a perfect symmetry to matter. Antimatter is very dangerous and powerful. When matter and antimatter collide, an annihilation happens. Things around it will disappear.
The matter of the astronaut causes the antimatter to anhilate each other, creating energy close to the energy produced by the equation E=mc2.
This question presupposes the existence of an antimatter reactor. As far as I know, no such reactor exists, or has even been designed. Antimatter reacts with matter to produce energy with virtually no matter remaining. Such a reaction is thousands of times more powerful as nuclear reactions we have used on this planet. But antimatter is difficult to make and nearly impossible to handle. As soon as it touches anything, it is gone. There is a lovely quote from a researcher who has made antimatter often. He said that if all the antimatter made at CERN were put together and reacted with matter, the resulting energy would power a light bulb for a few seconds. This even though it is the most powerful reaction we know of. There just is not enough of it to react usefully.
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".

This is not currently known. There does exist some asymmetry between matter and antimatter - meaning that they are not exact opposites in all aspects - but this asymmetry is not enough to explain why matter exists.

That is one of the unsolved problems in cosmology. There seems to be a slight difference between matter and antimatter, that is, the symmetry between matter and antimatter is not perfect. But the details of baryogenesis are not known yet.
antimatter particles are just like matter particles, except they have a negative charge. So, when anti matter collide with matter they would immediately annihilate each other. and we know that everything in our surroundings is matter, so it is difficult to store it. It can be only stored in Vacuum.
Matter, or antimatter.
no, everything that we can interact with is matter. antimatter completely demolishes itself if it comes into contact with its matter counterpart. the matter and antimatter together makes up the M (mass) of the E=MC squared equation. dark matter, which just passes right through matter and antimatter, which we call WIMPs, (Weakly Interacting Mass Particles or something. i forgot exactly)
When antimatter comes into contact with matter, they annihilate each other.
Initially the 9g of remaining matter would survive. Each particle of antimatter can only annihilate with one other particle of antimatter. At this point the 1g of antimatter would cause an explosion equivalent to that of 200000 pounds of TNT. Causing both groups of matter and antimatter to be obliterated.
