Stoichiometry is the calculation of relative quantities of reactants and products in chemical reactions. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers. This means that if the amounts of the separate reactants are known, then the amount of the product can be calculated. Conversely, if one reactant has a known quantity and the quantity of product can be empirically determined, then the amount of the other reactants can also be calculated. We begin this chapter by describing the relationship between the mass of a sample of a substance and its composition.

General Chemistry: Principles, Patterns, and Applications

But you may not have that much amount of time in your hands!! Last minute revision involves checking out all the formulae, diagrams of organic molecules etc. And jotting them down all at one place would require the same amount of time as it did when reading about them at first place. The given chapter-wise chemistry formulae sheets are in. They are downloadable and easy to print.

Publisher: Saylor Foundation. This text covers all of the major topics found in a two-semester, first year General Chemistry course and has the appropriate tables thermodynamic quantities, equilibrium constants, etc. The table of standard reduction Comprehensiveness rating: 3 see less. The table of standard reduction potentials Appendix E would be more difficult to use than most other textbooks as the potentials are listed alphabetically by symbol.

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 first chemical equation was diagrammed by Jean Beguin in A chemical equation consists of the chemical formulas of the reactants the starting substances and the chemical formula of the products substances formed in the chemical reaction. As an example, the equation for the reaction of hydrochloric acid with sodium can be denoted:. Using IUPAC nomenclature, this equation would be read as "hydrochloric acid plus sodium yields sodium chloride and hydrogen gas. It also indicates that two sodium molecules are required for every two hydrochloric acid molecules and the reaction will form two sodium chloride molecules and one diatomic molecule of hydrogen gas molecule for every two hydrochloric acid and two sodium molecules that react. The stoichiometric coefficients the numbers in front of the chemical formulas result from the law of conservation of mass and the law of conservation of charge see "Balancing Chemical Equation" section below for more information.

How to teach chemical formulas and equations

There are two versions of this current textbook, both containing the same information but organized differently: the "Chemistry-first" version begins with actual "chemistry" — that is, chemical equations and reactions. The alternative "Atoms-first" format saves this stuff for later, and begins with atomic theory and bonding. Each chapter can be downloaded as a separate pdf file; to see which one you need, move your mouse over the image and the title will appear. General Chemistry - a free textbook compiled from the work of various authors. Please see here for details.

Энсей решил пойти на собеседование. Сомнения, которые его одолевали, исчезли, как только он встретился с коммандером Стратмором. У них состоялся откровенный разговор о его происхождении, о потенциальной враждебности, какую он мог испытывать к Соединенным Штатам, о его планах на будущее. Танкадо прошел проверку на полиграф-машине и пережил пять недель интенсивного психологического тестирования. И с успехом его выдержал.
