Pure substances and mixtures

Matter is made up of tiny units called atoms. We currently know that there are 119 different types of atoms, which are the basis of the 119 elements of the periodic table (including “unnunennio” which […]

The chemistry of carbon

Since its beginnings in the 18th and 19th centuries, chemistry has been divided into two main branches: organic chemistry and inorganic chemistry. Organic Chemistry: It was associated with the chemistry of living beings and the […]

Changes of states of matter

Matter is everything that surrounds us that has mass and weight, that occupies a place in the space, that is perceptible by one of our senses and that is opposed to changing position, which is, […]

Empirical and molecular formula

The empirical formula is the simplest expression to represent a chemical compound. It tells us the elements that are present and the minimum proportion in whole numbers between their atoms. This formula is also known […]

Organic formulation. Cyclic Hydrocarbons.

Cyclic Hydrocarbons theory   Organic Formulation: Cyclic Hydrocarbons They are closed-chain hydrocarbons. Depending on whether or not they have unsaturations, they are classified as: Saturated monocyclic hydrocarbons (cycloalkanes). Unsaturated monocyclic hydrocarbons (cycloalkenes and cycloalkynes)   […]
