Pls H2: Top-notch Specifications, Comprehensive Comparisons, And Trusted Buying Sources
PLS H2 Information
the H2 information for you:
Intro
Hydrogen (H2) is the most abundant element in the universe, making up about 75% of all normal matter. It is a colorless, odorless, tasteless, non-toxic, and highly combustible gas. Hydrogen gas is highly flammable: 2 H2(g) + O2(g) → 2 H2O(l) (572 kJ/2 mol = 286 kJ/mol = 141.865 MJ/kg) The enthalpy of combustion is −286 kJ/mol. Hydrogen gas forms explosive mixtures with air in concentrations from 4–74% and with chlorine at 5–95%. The explosive reactions may be triggered by spark, heat, or sunlight. The hydrogen autoignition temperature, the temperature of spontaneous ignition in air, is 500 °C (932 °F).
