BALANCING REDOX REACTIONS BY THE ION-ELECTRON METHOD In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions is balanced separately and then combined to give the balanced redoxequation.
BALANCING REDOX EQUATIONS There are two common techniques for balancing redox equations: oxidation number change method ion-electron method (also called the half-reaction method). BALANCING REDOX REACTIONS BY AGGREGATE REDOX SPECIES METHOD The aggregate redox species method (or ARS method) is a variation of the oxidation number change method for balancing redox equations. In the ARS method all species with redox atoms are aggregated into one equation where the redox atoms and transfer of electrons are balanced and the stoichiometric coeffcients 'frozen'.GAS LAWS CALCULATOR
General gas equation. The ideal gas law is the equation of state of a hypothetical ideal gas. This equation was first stated by French engineer and physist Emile Clapeyron (1799-1864) in 1834 as a combination of three empirical gas laws proposed by Robert Boyle, Joseph Louis Gay-Lussac, and Amedeo Avogadro.

BALANCING REDOX REACTIONS BY THE ION-ELECTRON METHOD In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions is balanced separately and then combined to give the balanced redoxequation.

BALANCING REDOX REACTIONS BY AGGREGATE REDOX SPECIES METHOD The aggregate redox species method (or ARS method) is a variation of the oxidation number change method for balancing redox equations. In the ARS method all species with redox atoms are aggregated into one equation where the redox atoms and transfer of electrons are balanced and the stoichiometric coeffcients 'frozen'.

WHY IS THE PERIODIC TABLE SHAPED LIKE IT IS? Organization of chemical elements in alphabetical order by their names(or symbols
)
doesn't tell us anything about their properties but it is useful when searching for an element. We can list elements in order of increasingatomic number
but
it wouldn't be a periodic table any more. The periodic table is a chart that organizes the elements by increasing atomic number _and their chemical and physical properties_ (see article History of the Periodic table of elements).
Rows are arranged so that elements with similar properties fall into the same vertical columns ("groups"). * Long form of the periodic table The lanthanides and actinides should actually be placed in the middle of the table as well, after lanthanum and actinium, but, because of their similarity to each other, they are removed from the middle tosave space.
* Short form of the periodic table On periodni.com you can find two version of the periodic table * EniG.

* Electronic configurations of the elements - The electron configuration describes the distribution of electrons in the shell of an atom at various energy states. This is described by the occupied sub-shells. The shell number is followed by the letter of the sub-shell, with the number of electrons in the shell indicated by a superscript number. * Fundamental physical constants-
CODATA Recommended Values of the Fundamental Physical Constants: 2014. * Solubility product constants-
Solubility product constant (_K_sp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation. * SI - International System of Units- The
base quantities used in the International System of Units are length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. The corresponding base units of the SI were chosen by the CGPM to be the metre, the kilogram, the second, the ampere, the kelvin, the mole, and the candela. * Abbreviations and acronyms of chemical compounds- Standard
abbreviations and acronyms of chemical compounds used by the Journal of Organic Chemistry (JOC) require no definition. * NFPA 704 Hazard Diamond - NFPA 704: Standard system for the identification of the hazards of materials foremergency response.

diamond-shaped pictograms indicate the nature of the hazards associated with the use of a hazardous substance or mixture. Do you know what these pictograms mean? * Crystal systems and Bravais lattices-
Crystal system is a method of classifying crystalline substances on the basis of their unit cell. There are seven unique crystal systems: cubic, hexagonal, tetragonal, trigonal, orthorhombic, monoclinic andtriclinic.
STOICHIOMETRY
* Stoichiometric calculations - five steps to the solution-
Stoichiometric calculations are based on the equalization between the ratio of the amount of substance we're interested in, and the ratio of the corresponding absolute values of the stoichiometric numbers. Almost every single stoichiometric task can be solved in five easy steps, and with only a basic knowledge of mathematics. * Quantitative expression of composition of mixtures and solutions - The quantitative composition of a solution can be expressed with: concentration, fraction, ratio (molar, mass and volume), and molality.CHEMISTRY
* Rare earth elements (REE)- Rare earth
elements (REE) are a collection of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium andyttrium.
* History of the rare earth elements- The
close chemical similarity of the rare earth elements is displayed in their occurring together in nature and further by the fact that it took nearly 150 years to isolate and identify them. * Naming of elements of atomic numbers greater than 100- In 1978 IUPAC
Commission on the Nomenclature of Inorganic Chemistry decided that it is necessary to have a systematic naming for the elements with atomic number _Z_ > 100, even for those which had not been discovered. * History of the Periodic table of elements - Short history of how the Periodic table of chemical elements was arranged, from Lavoisier's Table of simple substances to SeaborgActinide concept.
* Chlorinity and salinity of seawater-
The most characteristic feature of seawater is its salty taste. Each liter of the ocean contains approximately 34 g of dissolved salts.ECOLOGY
Do follow us global warming, cooling or pollution?* Climate change -
Some will lie for money (privileges, power) while others will present data that support their 'truth', the third are exclusive and believe only in their own 'truth', the fourth are most likely right but they are lost in all this crowd. Which one of them is actually right, onlytime will tell.
* Global warming and mankind-
Greenhouse gasses are gasses that allow unhindered passage of short wave sunlight (visible part of the spectrum and ultraviolet radiation), and absorb long wave radiation (infrared radiation). * Story of ozone and ozone holes- The
effect of ozone depends on how far away we are from it: it poisons us in the cities (photochemical smog), it heats us in the troposphere (greenhouse gas) and protects us in the stratosphere (ozone layer). * World War 3: Battle for Earth- I
believe you all heard the old saying about how we did not inherit the Earth from our parents but are instead borrowing it from our children. If we want our children to be better follow us battle for Earth. * The ozone layer is not a shield, it is the remnant of UV radiationprotection
- Ozone does not have a shield that reflects ultraviolet radiation - it sacrifices itself for our protection. No matter how thick the ozone layer is it will simply disappear when illuminated. The ozone layer represents a "negative image" in terms of UV radiation protection. It is comprised of ozone molecules that UV photons did not hit and those that were not dissociated even though they were hit.WEBMASTER TOOLS
