Biedermeier
The ''Biedermeier'' period was an era in Central Europe between 1815 and 1848 during which the middle class grew in number and the arts appealed to common sensibilities. It began with the Congress of Vienna at the end of the Napoleonic Wars in 1815 and ended with the onset of the Revolutions of 1848.

It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements.

Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang.
