Inorganic Reactions
These are the different reactions in inorganic reactions.:- Combination reaction A Combination Reaction or a Synthesis Reaction is a   general category of a chemical reaction (the term usually   refers to an inorganic chemical reaction), in which two or   more reagents are chemically bonded together to produce a single product.   For example, the addition of sodium and chlorine to form sodium chloride or common table salt. 2Na(s) + Cl2(g) ? 2NaCl(s) is a combination reaction.   Chemical decomposition Chemical decomposition or analysis is the fragmentation of a chemical compound into elements or smaller compounds.   more ...

CHEMISTRY IN SPACE
CHEMISTRY IN SPACE       Like we always say... Matter is everywhere. So wherever matter is changing, chemistry won't be far behind! It's here on Earth, on the Moon, on Mars... Anywhere! While you, the chemist, sit here on Earth you don't have to study the chemistry of Earth. You could work with astronomers and geologists to study the chemistry of other planets and stars. You would not just study the surface of other planets. There are as many things to study on each planet we discover as there are on Earth. Examples... - Chemistry of atmospheres. - Chemistry and elemental makeup of stars. - Chemistry and elemental makeup of asteroids (those are e   more ...

nuclear weapons
Nuclear Weapons The mushroom cloud of the atomic bombing of Nagasaki, Japan, 1945, rose some 18 kilometers (11 mi) above the hypocenter A nuclear weapon is a weapon which derives its destructive force from nuclear reactions of fission or fusion. As a result, even a nuclear weapon with a small yield is significantly more powerful than the largest conventional explosives, and a single weapon is capable of destroying an entire city. In the history of warfare, nuclear weapons have been used only twice, both during the closing days of World War II. The first event occurred on the morning of 6 August 1945, when the United States dropped a uranium gun-type device code   more ...

Possible Existence of Anti-Matter in Bulk
For every particle (matter) there is a corresponding antiparticle (antimatter). Antiparticles are the same as the corresponding matter particle in every respect except for their opposite charges. A proton is electrically positive: an anti-proton is electrically negative. They both have the exact same mass, so they are affected in the same way by gravity. When a particle and its antiparticle meet, they annihilate into pure energy. This energy may then give rise to neutral force-carrier particles, such as photons, Z bosons, or gluons. The symbol for an antimatter particle is a bar over the corresponding matter particle symbol. For example, a proton ()   more ...
