Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: 2 H2 (g) + O2 (g) → 2 H2O (l) + 572 kJ (286 kJ/mol) Gasi rehydrogen rinoumba musanganiswa unoputika nemhepo mumirwi inobva pa 4<unk>74% uye neklorini pa 5<unk>95%. Mhinduro dzinoputika dzingaparirwa nechinhu chinoputika, kupisa, kana kuti chiedza chezuva. Tembiricha yehydrogen autoignition, tembiricha yekupisa kwega mumhepo, i500 °C (932 °F). Mvura yakachena yehydrogen-oxygen inopisa inobudisa chiedza che ultraviolet uye ine kusanganiswa kwe okisijeni yakawanda inenge isingaoneki kune ziso rakashama, sezvinoratidzwa nehupfumi husina simba hwe Space Shuttle Main Engine, zvichienzaniswa nehupfumi hunooneka hwe Space Shuttle Solid Rocket Booster, iyo inoshandisa ammonium perchlorate composite. Kuonekwa kwekudonha kwehydrogen inopisa kungada murazvo unoputika; kudonha kwakadaro kunogona kuva nengozi zvikuru. Moto wehydrogen mune mamwe mamiriro unenge uri webhuruu, wakafanana nemoto wegasi rebhuruu. Kuparadzwa kwechikepe cheHindenburg chaiva muenzaniso wakakurumbira wekupisa kwehydrogen uye chikonzero chacho chichiri kukurukurwa. Marimi eorenji anooneka muchinoitika ichocho akanga ari mugumisiro wesanganiswa rakapfuma rehydrogen kuoxygen yakabatanidzwa nemakemikari ecarbon anobva paganda redhivha.  Mubvunzo: gasi rehydrogen richava rinoputika rini?
