Ethan (mimo chemii dle PČP etan) je druhý nejjednodušší nasycený uhlovodík, patřící mezi alkany. Za normálních podmínek je to bezbarvý hořlavý plyn bez zápachu jen nepatrně těžší než vzduch. Ve směsi se vzduchem obsahující 3 až 12,5 % ethanu snadno exploduje.
The analysis highlights Vlastnosti, Příprava and Výskyt v přírodě as prominent areas in the source structure around Ethan.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
