Chemical equation - Wikipedia

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers.The first chemical equation was diagrammed by Jean Beguin ...

Covalent Bonds: Types of Chemical Formulas - dummies

There are several types of chemical formulas that you can use to represent chemical bonds. These include empirical formulas, molecular (or true) formulas, and structural formulas. You can predict the formula of an ionic compound based on the loss and gain of electrons, to reach a noble gas configuration. However, you really can't make that [.]

Chemical Equations and Calculations

A chemical equation expresses the net change in composition associated with a chemical reaction by showing the number of moles of reactants and products. But because each component has its own molar mass, equations also implicitly define the way in which the masses of products and reactants are related.
