In order to understand the chemistry of natural gas, it is important to be familiar with some basic concepts of general chemistry. Here are some definitions you should know:
Matter – anything that has mass and occupies space.
Energy – the capacity to do work or transfer heat.
Elements – substances that cannot be decomposed into simpler substances by chemical changes. There are approximately 112 known elements. Examples: carbon, oxygen, and nitrogen.
Atom – the smallest unit in which an element can exist. Atoms are composed of electrons, protons, and neutrons.
Compounds – pure substances consisting of two or more different elements in a fixed ratio. Examples: water and methane.
Molecule – the smallest unit in which a compound can exist or the normal form in which an element exists. Example: One molecule of water consist of two hydrogen atoms and one oxygen atom. One molecule of nitrogen consist of two atoms of nitrogen.
Mixture – combination of two or more pure substances in which each substance maintains its own composition and properties. Examples: natural gas, gasoline, and air.
