  2. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    This is illustrated in the image here, where the balanced equation is: CH 4 + 2 O 2 → CO 2 + 2 H 2 O. Here, one molecule of methane reacts with two molecules of oxygen gas to yield one molecule of carbon dioxide and two molecules of water. This particular chemical equation is an example of complete combustion. Stoichiometry measures these ...

  3. Oxygen balance - Wikipedia

    en.wikipedia.org/wiki/Oxygen_balance

    A molecule is said to have a positive oxygen balance if it contains more oxygen than is needed and a negative oxygen balance if it contains less oxygen than is needed. [2] An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or ...

  4. Octane - Wikipedia

    en.wikipedia.org/wiki/Octane

    Octane is a hydrocarbon and also an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the location of branching in the carbon chain .

  5. Oxygen reduction reaction - Wikipedia

    en.wikipedia.org/wiki/Oxygen_reduction_reaction

    The oxygen reduction reaction is an essential reaction for aerobic organisms. Such organisms are powered by the heat of combustion of fuel (food) by O 2.Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer.

  6. 2,2,4-Trimethylpentane - Wikipedia

    en.wikipedia.org/wiki/2,2,4-Trimethylpentane

    2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2. It is one of several isomers of octane (C 8 H 18 ). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n -heptane ).

  7. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Equations should be balanced according to the stoichiometry, the number of atoms of each species should be the same on both sides of the equation. This is achieved by scaling the number of involved molecules (A, B, C and D in a schematic example below) by the appropriate integers a, b, c and d .

  9. 2-Methyloctane - Wikipedia

    en.wikipedia.org/wiki/2-Methyloctane

    Where there is enough oxygen, nonane burns to form water and carbon dioxide, so 2-methyloctane would do the same. C 9 H 20 + 14 O 2 → 9 CO 2 + 10 H 2 O. When insufficient oxygen is present for complete combustion, carbon monoxide is produced. 2 C 9 H 20 + 19 O 2 → 18 CO + 20 H 2 O
