Helu CAS 1333-74-0 Hale Hana Hana. Nā ʻano o ka hydrogen
ʻO ka hydrogen, me ke ʻano kemika H₂ a me ka helu CAS 1333-74-0, ʻo ia ka māmā a me ka nui o ka mea kemika ma ke ao holoʻokoʻa. He ʻāpana koʻikoʻi ia i nā ʻoihana he nui a loaʻa iā ia nā waiwai kūʻokoʻa e waiwai ai i nā noi like ʻole. Eia kekahi mau hiʻohiʻona nui o ka hydrogen:
Nā waiwai kemika a me ke kino:
Moku'āina ma ka lumi lumi: He kinoea kala ʻole, ʻala ʻole a ʻono ʻole ka hydrogen i nā kūlana maʻamau.
Puni paila: -252.87°C (-423.17°F) ma 1 atm.
Lae hehee: -259.14°C (-434.45°F) ma 1 atm.
Māmā: 0.0899 g/L ma 0°C (32°F) a me 1 atm, ʻoi aku ka māmā ma mua o ka ea.
Solubility: Hiki ke hoʻoheheʻe ʻia ka hydrogen i ka wai a me nā mea hoʻoheheʻe ʻē aʻe.
ʻO ka hana hou ʻana:
Hiki i ke ahi: ʻAi ʻia ka hydrogen a pahū me ka oxygen.
ʻIke i ka ikehu: He kiʻekiʻe ka ikehu o ka hydrogen i kēlā me kēia ʻāpana, e lilo ia i kumu wahie maikaʻi.
ʻO ka hana hou me nā metala a me nā mea ʻole: Hiki i ka hydrogen ke hana me nā mea he nui e hana i nā hydride.
Hoʻohana:
Hana ʻia ʻo Ammonia: Hoʻohana ʻia kahi hapa nui o ka hydrogen i ke kaʻina Haber no ka hana ʻana i ka amonia, a laila hoʻololi ʻia i mau mea kanu.
Hoʻomaʻemaʻe Petroleum: Hoʻohana ʻia ka Hydrogen i nā ʻaila hinu no ka hydrocracking a me ka hydrodesulfurization.
ʻO ka ʻaila Rocket: Hoʻohana ʻia ka hydrogen wai ma ke ʻano he rocket propellant, pinepine i hui pū ʻia me ka oxygen wai.
Nā Pūnaehana wahie: Hoʻohana ʻia ka hydrogen i loko o nā pūnaewele wahie e hana ai i ka uila me ka ʻole o ka puhi ʻana.
Ka Hana Metala: Hoʻohana ʻia ka hydrogen i ka hana metala no ka wili a me nā hana ʻoki.
ʻOihana Meaʻai: Hoʻohana ʻia ka hydrogen i ka hydrogenation o nā aila e hana ai i ka margarine a me nā huahana ʻē aʻe.
