    en.wikipedia.org/wiki/Chemical_synthesis

    Key principles include atom economy, which aims to incorporate all reactant atoms into the final product, and the reduction of waste and inefficiencies in chemical processes. Innovations in green chemistry, contribute to more sustainable and efficient chemical synthesis, reducing the environmental and health impacts of traditional methods.

  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.

  4. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    This method is most useful when there are only two reactants. One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess and A is the limiting reagent.

    Also, some relatively minor additions to the reaction can be indicated above the reaction arrow; examples of such additions are water, heat, illumination, a catalyst, etc. Similarly, some minor products can be placed below the arrow, often with a minus sign. An example of organic reaction: oxidation of ketones to esters with a peroxycarboxylic acid

    Reactant: the numbers of each of the elements on the reactants side of the reaction equation. Product: the number of each element on the product side of the reaction equation. The layout should eventually look like this, for a balanced reaction of baking soda and vinegar: HC 2 H 3 O 2 + NaHCO 3 → NaC 2 H 3 O 2 + H 2 CO 3
