### Permutations Theory

Permutations Permutations are multiplicative events where the number of possibilities is decreasing and whether it is important the order of a permutation, it is an arrangement of a set of objects in a defined […]

### Organic formulation. Alkenes

Organic Formulation Theory: Alkenes Hydrocarbons with double bonds, Olefins or Alkenes. They are hydrocarbons having one or more double bonds between the carbon atoms. The general formula with a single double bond is CnH2n. […]

### Organic formulation. Alkanes.

Organic Formulation Theory: Alkanes Saturated hydrocarbons, paraffins or Alkanes They are called saturated hydrocarbons or alkanes all compounds made of carbon and hydrogen, which are of open-chain and have single bonds. Straight-chain alkanes. […]

### Divisibility theory

Divisibility Divisibility is the property of an integer number to be divided by another, resulting an integer number. Where a and b, two integers numbers, we will say that “a” is a multiple of […]

### The IUPAC is naming four new chemical elements

After the recent discover by russian, japanese and northamerican scientifics of four new chemical elements, the IUPAC (International Union of Pure and Applied Chemistry), http://iupac.org has shown the names with which they will be added to the […]

### Combined Operations theory

Combined Operations We call Combined Operations to those in which several arithmetic operations appear to be solved. To get the right result you need to follow some rules and take into account the priority […]

### Capacitance theory

Capacitance Capacitance is the ability of a body to store charge in an electric field. Capacitance is also a measure of the amount of electric potential energy stored (or separated) for a given electric […]

### Direct-Current theory

Direct-Current When it is connected a continuous conductive path, like a wire with a battery terminal, we obtain an electric circuit. The device which receives charging from a battery is not always a wire, […]

### Radicals theory

Radicals Radicals are expressions with the form: Where n Є N and a Є R; provided that when a is negative, n must be odd. n=index; a=radicand; m=exponent. A radical can be expressed […]
