![]() Many combustion reactions occur with a hydrocarbon, a compound made up solely of carbon and hydrogen. Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. ![]() The chemical reaction was a simple one: hydrogen combining with oxygen to produce water. In a common automobile, the internal combustion engine contains anywhere from four to eight combustion chambers. The combustion of hydrogen gas produces water vapor: 2H2(g) +O2(g) 2H2O(g) 2 H 2 ( g) + O 2 ( g) 2 H 2 O ( g) Notice that this reaction also qualifies. Combustion reactions must involve O2 O 2 as one reactant. The hydrogen immediately combusted in a huge fireball, destroying the airship and killing 36 people. A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Notice that this reaction also qualifies as a combination reaction.įigure 10.6.4: The Hindenburg was a hydrogen-filled airship that suffered an accident upon its attempted landing in New Jersey in 1937.
