H2is a diatomic gas molecule composed of two tightly joined atoms that strongly sharetheir outer electrons. It is an odorless, tasteless, and colorless gas lighter than air. Hydrogenis included in group 1 with the alkali metals because it has an oxidation state of +1 as dothe other alkali ...
Cellulose has a molecular formula of C6H10O5. One possible reaction is that cellulose is disassociated in inert gas upon heating to release H2O and to generate carbon residue. The reaction may be described by: C6H10O5→6C+5H2O However, this is different from the inventor's discovery. The...
Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. It is also the lightest element with a molecular mass of 2.016 kg/kmol. Hydrogen is a fuel with a higher heating value of 141,800 kJ/kg and a lower heating value of 120...
