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 Příprava, Vlastnosti and Historie 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.
High-confidence facts extracted from structured source data. Use them as anchors for further research.
Browse the complete topic structure, not only the most central items. Less prominent entities and concepts can reveal missing angles, specialized context and useful research gaps. Each item opens a new analysis centered on that subject.
