Acetylacetone is an organic compound that exists in two tautomeric forms that interconvert rapidly and are treated as a single compound in most applications.

Although the compound is formally named as the diketone form, pentane-2,4-dione, the enol form forms a substantial component of the material and is actually the favored form in many solvents.

It is a colourless liquid that is a precursor to acetylacetonate (acac), a common bidentate ligand.

It is also a building block for the synthesis of heterocyclic compounds.

A barcode is an optical, machine-readable, representation of data; the data usually describes something about the object that carries the barcode.

Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D).

Later two-dimensional (2D) codes were developed, using rectangles, dots, hexagons and other geometric patterns in two dimensions, usually called barcodes although they do not use bars as such.

Barcodes originally were scanned by special optical scanners called barcode readers.

Later applications software became available for devices that could read images, such as smartphones with cameras.

or pupil is a learner or someone who attends an educational institution.

In Britain those attending university are termed "students".

In the United States, and more recently also in Britain, the term "student" is applied to both categories.

In its widest use, student is used for anyone who is learning, including mid-career adults who are taking vocational education or returning to university.

When speaking about learning outside an institution, "student" is also used to refer to someone who is learning a topic or who is "a student of" a certain topic or person.
