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.

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

Makemake e ʻimi i nā kaulike ma waho pūnaewele, e hoʻāʻo i kā mākou polokalamu kelepona

E ʻimi i loko o kāu Android a i ʻole Iphone App Store no ka Chemical Equation Balancer me kēia lepili

ʻIke pū ʻia me kahi ʻano synthesis. ʻO kekahi ʻano o ka hopena hui pinepine pinepine ʻia ka hopena o kahi mea me ka oxygen e hana i kahi oxide. 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.

4Al + 3O₂ => 2Al₂O₃ C₂H₂ + 2HCHO => KAULA₂CCCH₂OH H₂SO₄ + 2NH₃ => (NH₄)₂SO₄ 3Mak + 2P => Mg₃P₂ (NH₂)₂CO + H₂ʻO => (NH₄)₂CO₃ 2CO + O₂ => 2CO₂ PH₃ + HClO₄ => PH₄ʻO ClO₄ E nānā i nā hopena o ka hui ʻana

Ka hopena palaho

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.
