Te Hononga Matū: Te Pūtake o te Hanganga Ngota
Ko te hononga matū he āhuatanga e ahu mai ana i ngā mea katoa e kitea ana e tātou i te ao. Ki te kore he hononga matū, e kore ngā ngota e hono hei hanga i ngā ngota, ā, ki te kore he ngota, e kore te matū e mōhiotia ana e tātou e noho. Mai i te hanganga o ngā hanganga māmā pēnei i ngā ngota wai ki ngā hanganga uaua ake pēnei i te DNA, he mea nui te mahi a ngā hononga matū ki te whakatau i ngā āhuatanga me te whanonga o ngā matū rerekē. Ka tūhuratia e tēnei tuhinga ngā momo hononga matū rerekē, te āhua o te hanganga, me ā rātou whakamahinga i roto i te oranga o ia rā.
Ngā Momo Here Matū
I te nuinga o te wā, ka taea te whakarōpū i ngā hononga matū ki ngā momo matua e toru: ngā hononga honohono, ngā hononga katote, me ngā hononga whakarewa. Heoi anō, he maha atu anō ngā momo hononga, pērā i ngā hononga hauwai me ngā kaha van der Waals, e tika ana kia whakaarohia.
1. Ngā Herenga Hononga
Ka puta he hononga honohono ina whakamahia e ngā ngota e rua tētahi, neke atu rānei, ngā takirua irahiko. Ko te tikanga, ka puta tēnei hononga i waenga i ngā ngota kore-whakarewa he rite, he rite rānei ō rātou irahiko.
– Ngā Āhuatanga me ngā Āhuatanga: Ko ngā ngota i hangaia mā roto i ngā hononga honohono he iti te ira kohua me te ira rewa, ā, kāore e kawe hiko i roto i te āhua totoka, wai rānei.
– Tauira Māmā: Ko te ngota wai (H₂O) he tauira noa o te hononga honohono. I roto i tēnei ngota, ka tohaina e te ngota hāora he takirua irahiko ki ia ngota hauwai.
Ka taea hoki te wehewehe i ngā hononga honohono ki ngā hononga honohono pōro me ngā hononga honohono kore-pōro. Ka puta ngā hononga honohono pōro ina he kore taurite te tohatoha o ngā irahiko i waenga i ngā ngota kua herea, pērā i roto i te ngota wai. I tetahi atu taha, ka puta ngā hononga honohono kore-pōro ina tohatohahia ngā irahiko kia ōrite, pērā i roto i te ngota hāora (O₂).
2. Ngā Here Ionic
Ka puta ngā hononga katote ina whakawhitia katoatia ngā irahiko mai i tētahi ngota ki tētahi atu ngota, ka hangaia he katione (ngā katote pai) me ngā anion (ngā katote kino), kātahi ka kukume tetahi ki tetahi. Ko te tikanga, ka puta tēnei hononga i waenga i ngā ngota whakarewa me ngā ngota kore-whakarewa.
– Ngā Āhuatanga me ngā Āhuatanga: He teitei te ira rewa me te ira kohua o ngā matū katote, ā, ka kawe hiko i roto i te āhua wai, i te āhua wairewa rānei, engari kāore i te āhua totoka.
– Tauira Māmā: Ko te konutai pūhaumāota (NaCl), e mōhiotia ana ko te tote tēpu, he tauira matarohia o te hononga ionic. Ka tukuna e te konutai (Na) tētahi irahiko ki te chlorine (Cl), ka hanga he ion konutai (Na⁺) me te ion chlorine (Cl⁻).
3. Ngā Herenga Whakarewa
Ko te hononga whakarewa he momo hononga e puta ana i waenga i ngā ngota i roto i te whakarewa. I roto i tēnei hononga, ka taea e ngā irahiko valence te neke haere puta noa i te hanganga whakarewa, ka hanga he 'moana o ngā irahiko' e karapoti ana i ngā iona whakarewa pai.
– Ngā Āhuatanga me ngā Āhuatanga: He pai ngā āhuatanga o ngā konganuku ki te kawe hiko me te wera, ā, he ngāwari, he ngāwari hoki.
– Tauira Māmā: Ko ngā konganuku pēnei i te rino (Fe) me te parahi (Cu) e whakaatu ana i ngā tauira noa o te hononga konganuku, ka taea e ngā irahiko te nekeneke noa.
Tētahi atu Here Hira
Ngā Here Hauwai
Ko te here hauwai he taunekeneke tika i waenga i te ngota hauwai e honoa ana ki tētahi ngota irahiko kore pēnei i te hāora, te hauota, te wheorā rānei, me tētahi atu ngota irahiko kore. Ahakoa he ngoikore ake i ngā here irahiko kore me te ioni, he mea tino nui tēnei here hei whakatau i ngā āhuatanga ā-tinana o ngā matū rerekē.
– Tauira Māmā: Kei roto i ngā ngota wai ngā here hauwai, ka taea e ia ngota hauwai mai i tētahi ngota wai te hanga here hauwai me tētahi ngota hāora mai i tētahi ngota tata.
Te kaha o Van der Waals
He ngoikore, he rangitahi ngā taunekeneke a ngā kaha o Van der Waals e puta ana i waenga i ngā ngota ngota, i ngā ngota rānei. Kei roto i ēnei kaha ko ngā kaha marara o Rānana me ngā kaha dipole-dipole.
– Tauira Māmā: He mea tino nui ngā kaha Van der Waals i roto i te whakaritenga me te pumau o te hanganga o ngā ngota koiora pēnei i te pūmua me te DNA.
Ngā Taupānga i roto i te Oranga o Ia Rā
He whānuitia ngā whakamahinga o ngā hononga matū i roto i ngā āhuatanga maha o tō tātou oranga, mai i ngā rauemi hanga whare ki te rongoā.
Ngā Rauemi me ngā Hangarau
Ko ngā rauemi o ia rā e whakamahia ana e tātou, pērā i te kirihou, te rapa, me ngā konganuku, ka tautuhia katoatia e ngā momo hononga matū e hangaia ana e rātou. Ko te pūtaiao rauemi, e ako ana i ngā āhuatanga me ngā whakamahinga o ngā rauemi, ka arotahi pinepine ki te whakahaere i ēnei hononga hei hanga rauemi me ngā āhuatanga e hiahiatia ana.
Te Rongoā me te Matū Koiora
I roto i ngā mara o te rongoā me te matū koiora, ko ngā hononga matū te pūtake o ngā tauhohenga katoa e puta ana i roto i te tinana. Ka whakawhirinaki ngā whākōkī, ngā homoni, me ngā rongoā ki ngā taunekeneke motuhake i waenga i ngā ngota ngota kua herea.
Pūngao
Ko ngā tukanga tahu wahie pūmua, ngā pūtau wahie rānei i roto i ngā waka hiko, e uru katoa ana ki te hanganga me te motu o ngā hononga matū. Mā te mārama ki ngā āhuatanga o ēnei hononga ka taea e tātou te whakawhanake i ngā puna pūngao whai hua ake, ā, he pai ake hoki mō te taiao.
Āhuatanga
Ko ngā huringa ora o ngā matū maha i roto i te taiao, pērā i te waro me te hauota, he raupapa o ngā tauhohenga e whakahaerehia ana e ngā hononga matū. Mā te mōhio ki ēnei hononga ka āwhina i ngā kaipūtaiao taiao ki te mārama me te aro atu ki te parahanga me te huringa āhuarangi.
Whakamutunga
Ko ngā hononga matū te tūāpapa o ngā hanganga me ngā āhuatanga katoa o te ao tūroa. Mā te mārama ki ngā momo hononga matū me te āhua o tā rātou mahi, ka hohonu ake te māramatanga ki te ao e karapoti nei i a tātou. Mai i ngā rauemi hangarau ki ngā tukanga koiora uaua, ko ngā hononga matū te kī ki ngā mahi auaha me ngā whanaketanga maha puta noa i ngā momo mara pūtaiao me ngā tono o ia rā. Mā te rangahau tonu i te mara o ngā hononga matū ka whakatuwhera tonu i ngā tatau ki ngā kitenga hou ka taea te whakarerekē i te āhua o tō tātou noho me te mārama ki te ao tūroa.
