Common types of chemical bonding

Common types of chemical bonding

Definition of chemical bond as the force holding together two atoms or groups of atoms forming an aggregate of ions or molecular species by lowering of energy. Ionic, covalent, and metallic are types of common bonds.

Chemical Equilibrium - Reaction, Definition, Examples, Types

Definition of the dynamic equilibrium point, reversible, irreversible, endothermic vs exothermic reactions, energy change, and equilibrium constant.

Why do chemical reactions occur?

This leading question can not be answered in a simple sentence. Because details study reveals that the two primary factors responsible for the feasibility of a chemical reaction.
1. The potential energy of the reacting system must be lowered by the reaction.
2. Reactants posses potentially to react because they must find a suitable path to react at a participle rate under specific conditions.

The fast concern with thermodynamics because it studies under chemical equilibrium but the second one constitutes the study of chemical kinetics.

10

SI units and dimension

SI units and dimension

The IUPAC recommended seven physical quantities that have thair own SI units and dimension. Other physical quantities like force, energy, work, specific heat, etc can be derived from the basic SI unit. But SI unit of luminous intensity or candela not needed in chemistry. It used in optical photochemistry but it included only for the shake of completeness.

11

Radioactive isotopes

Radioactive isotopes

Uranium-238 decay ultimately to stable radioactive isotopes of lead. The entire route involves eight alpha and six beta radiation.

Chemical kinetics

Chemical kinetics

Chemical kinetics reaction

Chemical kinetics deals with chemical engineering for calculating the rate of a chemical reaction. In the experimental study, chemical kinetic provides the information for the formulation of mechanism or molecular pathways of a reaction.

But very fast or very slow reactions can not discuss under chemical kinetics only a moderate rate of reaction discus.
