  2. 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.

  3. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    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 quantitative relationships, and is used to determine the amount of ...

  5. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    Note the transfer of electrons from Fe to Cl. Decomposition is also a way to simplify the balancing of a chemical equation. A chemist can atom balance and charge balance one piece of an equation at a time. For example: Fe 2+ → Fe 3+ + e − becomes 2Fe 2+ → 2Fe 3+ + 2e −; is added to Cl 2 + 2e − → 2Cl −; and finally becomes Cl 2 ...

    In thermochemistry, a thermochemical equation is a balanced chemical equation that represents the energy changes from a system to its surroundings.One such equation involves the enthalpy change, which is denoted with In variable form, a thermochemical equation would appear similar to the following:

  7. Law of multiple proportions - Wikipedia

    For example, if one tried to demonstrate it using the hydrocarbons decane (C 10 H 22) and undecane (C 11 H 24), one would find that 100 grams of carbon could react with 18.46 grams of hydrogen to produce decane or with 18.31 grams of hydrogen to produce undecane, for a ratio of hydrogen masses of 121:120, which is hardly a ratio of "small ...

    The Bills are 0-for-3 in playoff matchups against Mahomes and the Chiefs. So, to realize their mission for Super Bowl glory, it seems likely that they’ll have to beat the Chiefs again. Or else.

  9. Chemical formula - Wikipedia

    en.wikipedia.org/wiki/Chemical_formula

    An example is the condensed molecular/chemical formula for ethanol, which is CH 3CH 2 −OH or CH 3 CH 2 OH. However, even a condensed chemical formula is necessarily limited in its ability to show complex bonding relationships between atoms, especially atoms that have bonds to four or more different substituents .
