Stoichiometry is not only used to balance chemical equations but also used in conversions, i.e., converting from grams to moles using molar mass as the conversion factor, or from grams to milliliters using density. For example, to find the amount of NaCl (sodium chloride) in 2.00 g, one would do the following:
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
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.

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 ...
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 ...

The simple one-line balancing goes as follows: the two redox couples are written down as they react; As 3+ + Sn 2+ ⇌ As 0 + Sn 4+ One tin is oxidized from oxidation state +2 to +4, a two-electron step, hence 2 is written in front of the two arsenic partners.
While, as noted, chemical formulae do not have the full power of structural formulae to show chemical relationships between atoms, they are sufficient to keep track of numbers of atoms and numbers of electrical charges in chemical reactions, thus balancing chemical equations so that these equations can be used in chemical problems involving ...
