Avoid the use of <chem> and <math chem> markup notations: the plain-text character set is adequate for most chemical equations; the change in size and font form is jarring to the reader. The <ce> tag is a deprecated synonym for <chem>; see Help:Displaying a formula#Chemistry. Ionic equations are preferred to the
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.

Chemical formulae with deuterated solvents (for example, in NMR use) are customarily described with "D" as chemical symbol: CD 3 OD, methanol-d 4; CD 3 SOCD 3, DMSO-d 6 (regular notation would be C 2 H 3 O 2 H). These established systems are acceptable, provided they are consistent within an article.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
Many people apply individual rules, e.g. "to obtain length in centimeters multiply the length in inches by 2.54", but combining several such conversions is laborious and prone to mistakes. A better way is to use the factor-label method , which is closely related to dimensional analysis , and quantity calculus explained in sections 1.1 and 7.1 ...

The Hill system (or Hill notation) is a system of writing empirical chemical formulae, molecular chemical formulae and components of a condensed formula such that the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms next, and then the number of all other chemical elements subsequently, in alphabetical order ...
I agree this article reads mostly as a how-to; particularly the Balancing Equations section. I recommend keeping Ex. 1 from the Balancing Chemical Equations section and moving the rest of the section into a WikiHow or WikiBooks article. That would get across the important point, namely matter cannot be created or destroyed during a chemical ...
