Nā wehewehe ʻana i ka ʻike kemika

He aha ka hoʻohālikelike kemika?

ʻO ke kaulike kemika kahi ʻano o ka wehewehe ʻana i kahi hopena kemika ma kahi e pani ʻia ka inoa o kēlā me kēia mea kemika e kā lākou hōʻailona kemika.

I ka Equation Chemical, ke kuhikuhi nei ka pua i ke ʻaoʻao kahi e kū ai kahi hopena. No nā ʻaoʻao hoʻokahi, hōʻike mākou i ka pua mai ka hema a me ka ʻākau. No laila e hoʻopili nā mea ma ka hema, a ʻo ka mea ma ka ʻākau ka huahana.

Ka wehewehe ʻana o ke kaulike kaulike

ʻO ke kaulike kaulike kahi hoʻohālikelike hopena kemika kahi i like ai ka nui o ka hoʻouka a me ka helu o nā ʻoma no kēlā me kēia me ke ʻano no nā reactant a me nā ʻāpana. I nā huaʻōlelo ʻē aʻe, ua like ka nui a me ka uku ma nā ʻaoʻao ʻelua o ka hopena.

Nā laʻana o ke kaulike kaulike ʻole ʻia

ʻO nā reactant a me nā huahana o kahi hopena kemika i helu ʻia i ka hoʻohālikelike kaulike kaulike ʻole, akā ʻaʻole i hōʻike ʻia nā nui e pono ai e hoʻokō i ka mālama ʻana i ka nui. ʻO kēia hoʻohālikelike, no ka laʻana, kaulike ʻole i ka nui o ka nui no ka hopena ma waena o ka iron oxide a me carbon to form iron and carbon dioxide:

Fe2O3 + C → Fe + CO2

ʻOiai ʻaʻohe ʻona i nā ʻaoʻao ʻelua o ka hoʻohālikelike, kaulike ka uku (net net charge).
Ma nā ʻāpana reactant o ka hoʻohālikelike (i ka hema o ka pua), aia ʻelua mau ʻoma hao, akā hoʻokahi wale nō ma ka ʻaoʻao huahana (ʻākau o ka pua). Hiki iā ʻoe ke ʻōlelo ʻaʻole kaulike ke kaulike ʻoiai ʻaʻole ʻoe e helu i nā helu ʻē aʻe.
Ma nā ʻaoʻao hema a ʻākau hoʻi o ka pua, ʻo ka pahuhopu o ke kaulike ʻana i ka hoʻohālikelike e loaʻa ka helu like o kēlā me kēia ʻano o ka ʻoma. Hoʻopau ʻia kēia ma ka hoʻololi ʻana i nā coefficients hoʻohui (helu i kau ʻia i mua o nā formulate). ʻO nā kau inoa (nā helu liʻiliʻi ma ka ʻākau o kekahi mau ʻoma, e like me ka hao a me ka oxygen i kēia hihia) ʻaʻole loa e loli.

ʻO ka hoʻohālikelike kaulike:

He aha ka mea waiwai i loko o ke kemika?

E nānā, nā mea āpau i ʻike ʻia, me nā kino o mākou, he mau mea. Aia kekahi mau mea kūlohelohe e like me nā holoholona, ​​nā mea kanu, nā muliwai, ka lepo ... he mau mea hana.

Loaʻa nā mea kūlohelohe i kekahi mau ʻano mea like ʻole. A hana ʻia nā mea hana i nā mea hana. ʻO kēlā me kēia mea he mea waiwai a i ʻole ka hui ʻana o kekahi mau mea. ʻO kahi laʻana: ʻO Aluminika, nā lula, nā aniani, ...

He aha ko lākou waiwai?

Loaʻa i kēlā me kēia mea waiwai kekahi mau waiwai: mokuʻāina a ʻano paha (solid, wai, gas) kala, ʻala a me ka ʻono. I ka helu ʻana a i ʻole hiki ʻole ke hoʻoheheʻe ʻia i ka wai ... Kahi hoʻoheheʻe, kahi e hoʻolapalapa ai, umekaumaha kikoʻī, lawe uila.

A ʻo ka hiki ke hoʻololi i nā mea ʻē aʻe, e laʻa, ka hiki ke decompose, holo ... ʻo ia nā waiwai kemika.

He aha ka'Ātoma?

Hana ʻia nā mea āpau i nā mea liʻiliʻi liʻiliʻi, uila ʻole i kapa ʻia nā ʻoma. Aia he ʻumi miliona mau mea ʻokoʻa, akā ma luna wale nō o 100 mau ʻano ʻoma.

Aia ka atoma i kahi nucleus i hoʻopiʻi maikaʻi ʻia a me kahi pūpū i haku ʻia i hoʻokahi a ʻoi aku paha o nā electron i hoʻouku ʻia

Ma lalo o kekahi mau kūlana, nā mea hao a me nā mea pono ʻole i pane koke ʻia me ka oxygen. I ka manawa e hoʻā ʻia, hana wikiwiki ka magnesium me ka wikiwiki, e hana me ka oxygen mai ka lewa e hana i kahi lepo magnesium oxide maikaʻi.

Pili ka nui o nā hopena decomposition i ka wela, ka malamalama, a me ka uila e hoʻokomo i ka ikehu. ʻO nā hui binary nā mea i hoʻopili ʻia i ʻelua wale nō mea. ʻO ke ʻano maʻalahi o ka hopena i ka decomposition ke wā e haki kahi hui binary i loko o kāna mau mea. ʻO Mercury (II) ʻokikū, kahi paʻa ʻulaʻula, decomposes e hana i ka mercury a me ka oxygen oxygen i ka wā e wela ai. Eia kekahi, manaʻo ʻia kahi hopena ma ke ʻano he decomposition ʻoiai inā hoʻokahi a ʻoi paha o nā huahana he hui pū kekahi. Wāwahi kahi carbonate metala e hana i kahi oxide metal a me carbon gas dioxide. Kaleponi carbonate no ka laʻana decomposes into calcium oxide and carbon dioxide.
