CHEMICAL BONDS it's a chemical process
responsible for interactive attractions between atoms and molecules described by: the quantum mechanics and
the laws of quantum electrodynamics. this process cofiere stability to chemicals and states to maintain atoms
in molecules
H2
links between the molecule is
called intramolecular
INTRAMOLECULAR BONDS ARE:
METAL BONDS BONDS AROMATICOS
BONDSCOVALENT IONIC BONDS
BONDS
BONDS
UNE FORCE OR LINK TWO ATOMS
The opposite charges attract, because, being
together, acquire a more stable
situation when separated.
is the calculation of the quantitative ratios between the reactants and products in the course of a chemical reaction.
Reactants
Products
"In any chemical reaction mass is conserved, that is, the total mass of the reactants is equal to the total mass of products"
Law of definite proportions
when two or more elements are combined to form a particular compound do in a weight ratio unchanged.
When two or more elements are combined to provide more of a compound, a variable mass of one joins the other at a fixed mass, and has the first relationship and indistinct numbers canonical
stoichiometric coefficients
Is a set of rules or formulas used to name all the elements and chemical compounds.
Published in 1787 by Louis-Bernard Guyton de Morveau (1737-1816), Antoine Lavoisier (1743-1794)
IUPAC (International Union of Pure and Applied Chemistry) is the highest authority on chemical nomenclature, which is responsible for establishing the relevant rules.
