Nā ʻike hoihoi e pili ana i ke kemika He manawa kūpono loa e aʻo hou aʻe e pili ana i ka ʻepekema. Pili loa kēia ʻepekema i ka physics a me ka biology, a me nā palena palena ʻē aʻe.
No laila, eia nā ʻike hoihoi loa e pili ana i ke kemika.
- No ke kākoʻo ʻana i ka lele o kahi mokulele mokulele maʻamau, a hiki i 80 tone o ka oxygen e koi ʻia. Hoʻopuka kēia nui o ka oxygen i 40,000 hectares o ka ulu lāʻau.
- Mai ka 1 ton o ke kai kai, hiki ke kiʻi ʻia he 7 mg gula.
- ʻO nā mea ʻike a pau, ʻike ʻia ka granite ke alakaʻi maikaʻi loa o ke kani.
- ʻO kahi mea hoihoi ʻoi aku ka hū o kahi hua kopa ma kahi wale nō 0,001 kekona.
- Loaʻa i hoʻokahi lita o ka wai kai ma kahi o 20 g paʻakai.
- ʻO ka mea kemika rarest loa i ka lewa ʻo radon.
- Wahi a nā helu ʻepekema, ma nā kenekulia 5 i hala, ua hoʻonui ʻia ka nui o ka Honua ma kahi o 1 biliona mau tona.
- Huli ka hao i kahi kūlana kinoea i ka mahana o 5000 ° C.
- Inā pelu ʻia nā ʻoma hydrogen he 100 miliona i hoʻokahi laina, a laila 1 cm ia.
- ʻIke paha ʻoe i loko o 1 mau minuke e hoʻopuka ai ka Lā i kahi nui o ka ikehu e lawa no kā mākou honua honua no hoʻokahi makahiki holoʻokoʻa?
- ʻO 75% ka wai o ke kanaka (e ʻike i nā mea hoihoi e pili ana i ka wai).
- ʻOi aku ka kaumaha o ka platug nugget ʻoi loa ma luna o 7 kg.
- Ua lawe ʻo Pyotr Stolypin i kahi hoʻokolohua ma ka kemika mai Dmitry Mendeleev iho.
- ʻO Hydrogen ka māmā o nā kinoea āpau.
- ʻO ka hydrogen like ka mea i manaʻo ʻia he mea kemika nui loa i ka honua.
- Pale ka Earwax i ko mākou kino mai ka bacteria a me nā microorganism ʻino.
- I ka 1 kekona wale nō, hiki i ka 100,000 mau hopena kemika i loko o ka lolo o ke kanaka.
- ʻO kahi mea hoihoi ʻo ia ʻo Ernest Rutherford ka mea mua i loaʻa i ka Nobel Prize in Chemistry.
- ʻAʻole ʻike ka poʻe āpau he waiwai antibacterial ka kālā e kōkua i ka hoʻomaʻemaʻe i ka wai mai nā mea ʻino a me nā mea koʻohune ʻino.
- Ua kūʻai mua ʻia ʻo Platinum ma lalo o ke kālā no ka infusibility.
- ʻO ka mea ʻike i nā lāʻau ʻaloʻalo ka mea loea kaulana ʻo Alexander Fleming.
- Maopopo iā ʻoe ua huli ka wai wela i ka hau ma mua o ka wai anuanu?
- E like me kēia lā, aia ka wai maʻemaʻe ma Finlandia (ʻike i nā mea hoihoi e pili ana iā Finilani).
- I mea e ʻōmaʻomaʻo ai ka lapalapa, ua lawa ia e hoʻohui i ka boron iā ia.
- Hiki i ka Nitrogen ke hoʻonāukiuki i kahi ʻōpua o ka noʻonoʻo.
- E hoʻoikaika i ke kila, hoʻohana ʻia kahi mea kemika e like me ka vanadium.
- Inā hele ʻia ka uila ma o ka neon, ʻulaʻula mai ka ʻula.
- I ka hana ʻana i nā match, ʻaʻole wale nō ka sulfur i hoʻohana ʻia, akā ʻo ka phosphorous hoʻi.
- Hiki ke hana i nā mea ʻokoʻa he nui e carbon dioxide.
- Loaʻa ka nui o ka calcium i nā huahana waiū.
- ʻO kahi mea hoihoi ʻo ia ka manganese hiki ke hoʻoulu i ka ona o ke kino.
- Hoʻohana ʻia ʻo Cobalt i ka hana ʻana i nā mākēneki.
- Ma waena o nā leʻaleʻa o ke kaimaka kaulana ʻo Dmitry Mendeleev ka hana ʻana i nā ʻeke.
- ʻO ka pīhoihoi, hiki ke hoʻoheheʻe i nā puna o ka gallium i loko o ka wai wela.
- Ke kūlou ikaika ʻana, kani ke ʻano o ka kemikala indium i kahi kani paʻakikī.
- Manaʻo ʻia ʻo Cesium ka mea hao hana (ʻike i nā mea hoihoi e pili ana i nā metala).
- ʻO kekahi o nā metala ʻoi loa refractory ʻo ka tungsten. Mai ia mea e hana ai nā ʻoni i nā kukui uila.
- Loaʻa i ka Mercury kahi pae heheʻe haʻahaʻa.
- Hiki i nā liʻiliʻi o ka methanol ke kumu o ka nalo ʻana o ka hihi.
- ʻIke ʻia i loko o ka wai wela hiki ʻole ke hemo i nā stains mai nā huahana protein.
