1.1 products of combustion reactions

• cellular respiration: the process by which cells convert the chemical energy stored in organic molecules (sugars) into energy that cells can use
• combustion: a chemical reaction that occurs in the presence of oxygen and results in the release of energy
• hydrocarbon: a compound containing only carbon and hydrogen atoms
• fuel: a substance that releases energy when involved in a chemical reaction (often combustion) or a nuclear reaction
• emission: a substance discharged into the atmosphere or into surface water
• sour gas: natural gas that contains greater than 1% hydrogen sulfide
• carcinogen: any agent that causes the likelihood of cancer to increase. Many carcinogens are also mutagens
