     • Acid : a substance that produces hydrogen ions when dissolved in water
     • Base : a substance that produces hydroxide ions when dissolved in water
   • Combustion Reaction : the burning of a hydrocarbon in the presence of ocygen to produce products such as water and carbon dioxide
     • Incomplete Combustion : the burning of a hydrocarbon in a limited supply of oxygen, resulting in a combination of products of soot, carbon dioxide, water, carbon monoxide, and energy
   • Metallurgy : the science of obtaining and refining metals from their ores (Application)
     • Flash Smelting : separating a metal from its ore by heating it in pure oxygen to high temperatures
   • Remediation : the process of removing contaminates from land or water so that it is safe for the environment (Application)
     • Bioremediation : using living organisms to treat contaminate soil or water
