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.

2 C 2 H 6 + 7 O 2 → 4 CO 2 + 6 H 2 O + 3120 kJ. Combustion may also occur without an excess of oxygen, yielding carbon monoxide, acetaldehyde, methane, methanol, and ethanol. At higher temperatures, especially in the range 600–900 °C (1,112–1,652 °F), ethylene is a significant product: 2 C 2 H 6 + O 2 → 2 C 2 H 4 + 2 H 2 O
The following table lists the Van der Waals constants (from the Van der Waals equation) for a number of common gases and volatile liquids. [ 1 ] To convert from L 2 b a r / m o l 2 {\displaystyle \mathrm {L^{2}bar/mol^{2}} } to L 2 k P a / m o l 2 {\displaystyle \mathrm {L^{2}kPa/mol^{2}} } , multiply by 100.
The molecular formula C 2 H 6 O 2 (molar mass: 62.07 g/mol, exact mass: 62.03678 u) may refer to: Ethylene glycol (ethane-1,2-diol) Ethyl hydroperoxide; Methoxymethanol;
The molecular formula C 2 H 6 O (molar mass: 46.07 g/mol, exact mass: 46.0419 u) may refer to: Dimethyl ether (DME, or methoxymethane) Ethanol; Other.
2H 2 O → O 2 + 4H + + 4e − Oxidation (generation of dioxygen) 4H + + 4e − → 2H 2 Reduction (generation of dihydrogen) 2H 2 O → 2H 2 + O 2 Total Reaction Of the two half reactions, the oxidation step is the most demanding because it requires the coupling of 4 electron and proton transfers and the formation of an oxygen-oxygen bond.
The Bosch reaction is a catalytic chemical reaction between carbon dioxide (CO 2) and hydrogen (H 2) that produces elemental carbon (C,graphite), water, and a 10% return of invested heat. CO 2 is usually reduced by H 2 to carbon in presence of a catalyst (e.g. iron (Fe)) and requires a temperature level of 530–730 °C (986–1,346 °F).
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.
