hydrogen has been researched along with Hypercapnia in 34 studies
Hydrogen: The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas.
dihydrogen : An elemental molecule consisting of two hydrogens joined by a single bond.
Hypercapnia: A clinical manifestation of abnormal increase in the amount of carbon dioxide in arterial blood.
