  2. 2-Methylhexane - Wikipedia

    en.wikipedia.org/wiki/2-Methylhexane

    On the NFPA 704 scale, 2-methylhexane is listed as a reactivity level-0 chemical, along with various other alkanes. In fact, most alkanes are unreactive except in extreme conditions, such as combustion or strong sunlight. At the presence of oxygen and flame, 2-methylhexane, like heptane, combusts mostly completely into water and carbon dioxide.

  3. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    That is, the heat of combustion, ΔH° comb, is the heat of reaction of the following process: C c H h N n O o (std.) + (c + h ⁄ 4 - o ⁄ 2) O 2 (g) → c CO 2 (g) + h ⁄ 2 H 2 O (l) + n ⁄ 2 N 2 (g) Chlorine and sulfur are not quite standardized; they are usually assumed to convert to hydrogen chloride gas and SO 2 or SO

  5. Standard enthalpy of reaction - Wikipedia

    en.wikipedia.org/wiki/Standard_enthalpy_of_reaction

    Standard enthalpy of combustion is the enthalpy change when one mole of an organic compound reacts with molecular oxygen (O 2) to form carbon dioxide and liquid water. For example, the standard enthalpy of combustion of ethane gas refers to the reaction C 2 H 6 (g) + (7/2) O 2 (g) → 2 CO 2 (g) + 3 H 2 O (l).

  6. Chemical thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Chemical_thermodynamics

    (The heat change at constant pressure is called the enthalpy change; in this case the widely tabulated enthalpies of formation are used.) A related term is the heat of combustion, which is the chemical energy released due to a combustion reaction and of interest in the study of fuels.

  7. Fire triangle - Wikipedia

    en.wikipedia.org/wiki/Fire_triangle

    Combustion is a chemical reaction that feeds a fire more heat and allows it to continue. Once a fire has started, the resulting exothermic chain reaction sustains the fire and allows it to continue until or unless at least one of the elements of the fire is blocked: foam can be used to deny the fire the oxygen it needs

  9. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    Incomplete reaction at higher temperature further curtails the effect of a larger heat of combustion. [citation needed] Because most combustion processes that happen naturally occur in the open air, there is nothing that confines the gas to a particular volume like the cylinder in an engine.
