  2. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    This is illustrated in the image here, where the balanced equation is: CH 4 + 2 O 2CO 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. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. [1]

  4. Oxygen reduction reaction - Wikipedia

    en.wikipedia.org/wiki/Oxygen_reduction_reaction

    Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer. The direct reaction of O 2 with fuel is precluded by the oxygen reduction reaction, which produces water and adenosine triphosphate. Cytochrome c oxidase affects the oxygen reduction reaction by binding O 2 in a heme ...

    In this particular case, Dalton was mistaken about the formulas of these compounds, and it wasn't his only mistake. But in other cases, he got their formulas right. The following examples come from Dalton's own books A New System of Chemical Philosophy (in two volumes, 1808 and 1817): Example 1 — tin oxides: Dalton identified two types of tin ...

  6. Carbon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–oxygen_bond

    A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1] [2] [3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides, carbonates and metal carbonyls, [4] and in organic compounds such as alcohols, ethers, and carbonyl compounds.

  8. Carbon trioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_trioxide

    Carbon trioxide (CO 3) is an unstable oxide of carbon (an oxocarbon).The possible isomers of carbon trioxide include ones with molecular symmetry point groups C s, D 3h, and C 2v.

  9. Water–gas shift reaction - Wikipedia

    en.wikipedia.org/wiki/Water–gas_shift_reaction

    This is sometimes called the reverse water–gas shift reaction. [20] Water gas is defined as a fuel gas consisting mainly of carbon monoxide (CO) and hydrogen (H 2). The term 'shift' in water–gas shift means changing the water gas composition (CO:H 2) ratio. The ratio can be increased by adding CO 2 or reduced by adding steam to the reactor.
