He mea maʻemaʻe anei ka uea keleawe (no ke aha a no ke aha?)
Nā mea
- He mea maʻemaʻe anei ke keleawe (no ke aha a i ʻole)?
- No ke aha e hiki ole ai ke keleawe ke maemae?
- ʻO ke keleawe kekahi mea?
- He mea hui anei ke keleawe?
- He huikau anei ke keleawe?
- He aha ka mea hiki ke komo i ke kaula keleawe?
- He huikau anei ka uwea keleawe?
- He hui like ʻole a heterogeneous paha ka uea keleawe?
- ʻokoʻa ma waena o ka mea maʻemaʻe a me ka hui ʻana
No ka hoʻokaʻawale ʻia ʻana ma ke ʻano he mea maʻemaʻe, pono e haku ʻia kahi mea a hui pū ʻia me hoʻokahi ʻano atom a mole. ʻO ka ea, ka wai a me ka nitrogen nā laʻana maʻamau o nā mea maʻemaʻe. Akā, pehea ke keleawe? He mea maemae anei ka uwea keleawe?
ʻAe, he mea maʻemaʻe ka uea keleawe. ʻO ia wale nō nā ʻātoma keleawe. Akā naʻe, ʻaʻole pololei kēia ʻōlelo i nā manawa a pau. I kekahi manawa hiki ke hui ʻia ke kaula keleawe me nā metala ʻē aʻe. Ke hiki mai kēia, ʻaʻole hiki iā mākou ke hoʻokaʻawale i ka uea keleawe ma ke ʻano he mea maʻemaʻe.
He mea maʻemaʻe anei ke keleawe (no ke aha a i ʻole)?
Hiki iā mākou ke hoʻokaʻawale i ke keleawe ma ke ʻano he mea maʻemaʻe i loaʻa i kēia metala he mau ʻātoma keleawe wale nō. Eia ka mahele electron a me proton o ke keleawe.
No ke aha e hiki ole ai ke keleawe ke maemae?
E like me ka mea i ʻōlelo ʻia ma luna nei, no ka lilo ʻana i mea maʻemaʻe, pono e loaʻa i kahi mea a i ʻole hui pū ʻia i hoʻokahi wale nō ʻano o ka poloka hale. He mea like paha ia e like me ke gula a i ʻole kahi hui e like me ka paʻakai.
Manaʻo kōkua: Hoʻokumu ʻia ka paʻakai mai ka sodium a me ka chlorine.
Eia naʻe, ʻaʻole e noho kēia mau mea a me nā pūhui i ko lākou ʻano maʻemaʻe i nā manawa a pau. No laila, hiki ke hui ʻia ke keleawe me nā mea ʻē aʻe. No ka laʻana, ma muli o ka haumia, hiki ke hui pū ke keleawe me nā mea ʻē aʻe.
ʻOiai ke kapa nei mākou i ke keleawe ma ke ʻano he mea maʻemaʻe, ʻike paha ʻoe i nā ʻāpana keleawe ʻaʻole keleawe maʻemaʻe.
ʻO ke keleawe kekahi mea?
ʻAe, me ka hōʻailona Cu, ʻo ke keleawe kekahi mea i loaʻa nā ʻano o kahi metala palupalu a ductile. ʻO ke keleawe ka helu 29 ma ka papaʻaina. I loko o ka metala keleawe, hiki iā ʻoe ke loaʻa nā ʻātoma keleawe wale nō.
He kiʻekiʻe ka conductivity uila ke keleawe. He ʻulaʻula-ʻalani ka ʻili keleawe i ʻike ʻia.
ʻO kēlā me kēia mea i ʻike ʻia ʻaʻole hiki ke hoʻokaʻawale ʻia i nā mea ʻē aʻe i kapa ʻia he element. No ka laʻana, ʻo ka oxygen kekahi mea. A ʻo ka hydrogen kekahi mea. Akā ʻaʻole ka wai kahi mea. Hana ʻia ka wai me ka oxygen a me ka hydrogen atoms. No laila, hiki ke hoʻokaʻawale ʻia i ʻelua mau mea like ʻole.
He mea hui anei ke keleawe?
ʻAʻole, ʻaʻole hui pū ke keleawe. No ka manaʻo ʻia he pūhui, pono ʻelua mau mea ʻokoʻa e hoʻopaʻa i kekahi i kekahi. No ka laʻana, ʻo ka carbon dioxide kahi hui. Hana ʻia ia me ke kalapona a me ka oxygen.
He huikau anei ke keleawe?
ʻAʻole, ʻaʻole hui pū ke keleawe. No ka hoʻokaʻawale ʻia ʻana ma ke ʻano he hui ʻana, pono e haku ʻia ka mea i hoʻopaʻa ʻia me ʻelua mau mea ʻokoʻa. Eia naʻe, pono kēia mau mea i loko o ka māhele kino like. Eia kekahi, pono e hoʻopaʻa ʻole ka waiwai.
Hoʻokahi wale nō mea ke keleawe, a no laila ʻaʻole hui pū ke keleawe.
Eia naʻe, hiki ke kapa ʻia kekahi mau huahana keleawe ma ke ʻano he hui. No ka laʻana, hoʻohui nā mea hana i nā metala ʻē aʻe me ke keleawe e hoʻololi i ko lākou ʻano kino. Eia kekahi mau laʻana o nā hui keleawe.
- Metala paheʻe (Cu - 95% a me Zn - 5%)
- Ke keleawe pahu pahu (Cu - 70% a me Zn - 30%)
- Ke keleawe Phosphor (Cu – 89.75 % a me Sn – 10 %, P – 0.25 %)
Inā ʻoe e ʻimi nei i kekahi mau hiʻohiʻona ʻē aʻe, ʻo ka wai paʻakai a me ka wai kō ka mea i hoʻohana pinepine ʻia i kēlā me kēia lā.
He aha ka mea hiki ke komo i ke kaula keleawe?
ʻO ka hapa nui o ka manawa, hiki ke hoʻokaʻawale ʻia ke kaula keleawe ma ke ʻano he mea maʻemaʻe. ʻO ia wale nō nā ʻātoma keleawe. Eia naʻe, e like me ka mea i ʻōlelo ʻia ma mua, hoʻohui kekahi mau mea hana i nā metala ʻē aʻe e hoʻololi i nā ʻano kino o ka uea keleawe. Hoʻomaka ʻia kēia mau hoʻololi e hoʻomaikaʻi i ka ikaika a me ka lōʻihi o ka uea keleawe. ʻO nā hiʻohiʻona maʻamau he keleawe, titanium a me ke keleawe. No laila, inā mākou e noʻonoʻo i ka uea keleawe ma ke ʻano holoʻokoʻa, a laila ʻaʻole he mea maʻemaʻe ka uea keleawe.
He huikau anei ka uwea keleawe?
Pili ia i ke ʻano o ka uea keleawe. Inā hoʻokomo wale ka uea keleawe i ke keleawe maʻemaʻe, ʻaʻole hiki iā mākou ke noʻonoʻo i ka uea keleawe ma ke ʻano he hui. Akā inā loaʻa nā metala ʻē aʻe i ka uea keleawe, hiki ke hoʻopaʻa inoa ʻia ma ke ʻano he hui.
He hui like ʻole a heterogeneous paha ka uea keleawe?
Ma mua o ka ʻike ʻana i ke ʻano o ka hui keleawe keleawe, pono ʻoe e hoʻomaopopo maikaʻi i nā ʻano like ʻole o ka pūhui. Ma ke kumu, ʻelua ʻano hui ʻana; ʻO ka hui like ʻole a i ʻole ka hui like ʻole. (1)
Huihui homogeneous
Inā he chemically homogeneous nā mea i loko o ka hui ʻana, kapa mākou he hui homogeneous.
huikau heterogeneous
Inā he ʻano kemika nā mea i loko o ka hui ʻana, kapa mākou iā ia he hui ʻokoʻa.
No laila, i ka wā e pili ana i ka uea keleawe, inā he keleawe wale nō, hiki iā mākou ke kapa iā ia he mea homogeneous. E hoʻomanaʻo, ʻo ka uea keleawe he mea homogeneous wale nō, ʻaʻole he hui like ʻole.
Eia nō naʻe, inā i haku ʻia ka uea keleawe me nā metala ʻē aʻe, ua like kēia hui ʻana.
E hoʻomanaʻo: Hiki ke loaʻa nā ʻano o nā uea keleawe ʻaʻole like ʻole kemika. ʻO kēia ma muli o kahi hemahema o ka hana ʻana. ʻO ia hoʻi, ʻaʻole hana ka uea keleawe ma ke ʻano he metala ikaika. Akā, me ka ʻenehana hou, paʻakikī ka loaʻa ʻana o ia mau uea keleawe.
ʻokoʻa ma waena o ka mea maʻemaʻe a me ka hui ʻana
Hoʻokahi wale nō ʻano o ka ʻātoma a i ʻole hoʻokahi ʻano mole. Pono e hana ʻia kēia mau molekele mai hoʻokahi ʻano mea.
No laila, e like me kāu e hoʻomaopopo ai, hoʻokahi wale nō ʻano o ka atom, a he mea maʻemaʻe kēia.
Pehea ka wai wai?
Hoʻokumu ʻia ka wai wai me ka oxygen a me ka hydrogen atoms, a lilo lākou i H2O. Eia kekahi, ʻo ka wai wai wale nō ka H2Molecules O. No ia mea, he mea maemae ka wai wai. Eia kekahi, ʻo ka paʻakai papa, aka NaCl, he mea maʻemaʻe. Loaʻa i ka NaCl nā ʻātoma sodium a me chlorine wale nō.
ʻO nā mea i hana ʻia me nā ʻano molekole a i ʻole nā mana i loaʻa ʻole kahi ʻano maʻamau i ʻike ʻia he hui. ʻO ka laʻana maikaʻi loa he vodka.
Hoʻokumu ʻia ʻo Vodka i nā molekole ethanol a me nā molekole wai. Hoʻohui like ʻole kēia mau molekole me kekahi i kekahi. No laila, ʻo ka vodka kahi hui. Hiki ke helu ʻia ʻo Salami ma ke ʻano he hui. Loaʻa iā ia nā momona a me nā protein i haku ʻia me nā molekala like ʻole. (2)
