The discovery of Plutonium was not announced until 1946 because America was at war with Japan and Germany. Plutonium was named after the planet Pluto, after the planet Neptune in the solar system and Neptune gave its name to Neptunium.

Sulfuric Acid Essay, Research Paper Acids & Bases An acid is any compound that can respond to a base to form a salt. Also, it is a substance that generates the positive ion of the solvent where the acid is dissolved. A base is the opposite of an acid. It is a substance that eliminates the hydrogen ions (protons) from an acid and joins them through a chemical reaction.

Essay, Research Paper In the past decade there has been a great deal of worrying about what will happen when the world?s oil supply becomes depleted. The main reason for concern is that almost all of the automobiles in use now require an oil based gasoline to run their internal-combustion engines. In the next few decades it is predicted that all of the world?s oil will have already been mined, and combustion engines will be unable to function.
