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)   […]
