Heterogeneous siyana - pachena uye nyore!

Vadzidzi vazhinji vanotsutsumwa kuti havasi kunzwisisa kemisitiri uye funga izvozvo chimwe chezvinhu zvakaoma nyaya chikoro. Somuenzaniso, mumwe okuti "heterogeneous maitiro" anoratidza vadzidzi vakawanda kutya. Mune dzimwe nzira, ivo hapana mubvunzo zvakanaka. Asi pamwe kemesitiri kunogona uye kunofanira kuva shamwari. It unopoteredza hwedu kwose kwose. zano Most zvakanaka vadzidzi vakatsunga kuita shamwari ichi nesayenzi zvakaoma - mudzidzisi kudzidzisa kupiwa zvinhu neimwe chidzidzo. Kuti vagadzirire makirasi kwete nheyo: "Nhasi handina kubvunza - ipapo haukwanisi kudzidzisa!", Asi papfungwa: "Ndinoda kuziva uye kunzwisisa zvose, kunyange zvakadaro uchadzidza chii handina kukumbira!". Chete chete kwakadaro yokutaura kuti mabhizimisi kemisitiri uchava kwauri bhuku yakazaruka. Uye uchanzwisisa uye ona payo zvose muupenyu hwedu.

Munyaya ino tichakurukura pfungwa chete ichi makemikari chinhu sechinhu heterogeneous maitiro. How kunzwisisa ichi izwi? Kana shoko kuita zvakawanda kana zvishoma zvakajeka (zvinoreva kuti kukurukurirana pamusoro zvinhu), pano shoko "heterogeneous" - mune zvinetso zvakawanda chikoro. Pano tinofanira kuyeuka shanduro rechiGiriki "geteros" - zvakasiyana, siyana.

Heterogeneous maitiro: mienzaniso kubva upenyu

Heterogeneous siyana kutora nzvimbo pakati siyana zvakasikwa, asi zvinhu mamiriro fuma. Mumwe chikoro chepuraimari mudzidzi mumwe nomumwe anoziva kuti chero fuma uve rehurumende aggregation 3 (kana 3 maitikiro) sezvo yakasimba, ine mvura kana gaseous mamiriro. Saka, zviri sechinhu heterogeneous maitiro kana zvinhu kupinda mariri, vari akasiyana in aggregation Somuenzaniso:

• gasi + mvura
• gasi + chikukutu
• mvura + hwakasimba.

Kana zvinhu izvo sei nemumwe vari chete ezvinhu aggregation, siyana zvakadai dzinonzi homogeneous. Shoko rinogona kushandurwa kubva muchiGiriki, "gomos" - zvakafanana, zvakafanana.

Homogeneous uye heterogeneous siyana vanowanzorwara kuitika muupenyu hwedu. Somuenzaniso, zvakaitwa namatanda combustion. Huni - ndiko, uye makuru, ane kemikari ine makemikari kwakabva - cellulose. Pasina mubvunzo, huni - a fuma iri yakasimba ezvinhu. Ndivo vanopisira nokuda kuitwa okisijeni. Okisijeni - ari gasi. Somugumisiro, mashoko combustion zvakaitwa kuti huni wakaumba marasha, carbon dioxide inobvisa uye mvura. Combustion huni sezvo rinopfuta doro - a heterogeneous maitiro. Mienzaniso anogona kuunzwa kusaverengeka.

1) Rusting simbi. Chekutanga, makemikari maitiro, nekuti mugumisiro nefuma itsva achiumbwa nesimbi - ngura simbi hydroxide (III). Chechipiri, ndiko heterogeneous chichiitwa, sezvo simbi - ndiyo yakasimba uye mvura uye mhepo okisijeni, kunobva pasi pokudzora rusting - iri mvura uye gasi azvaitwa. Izvi zvinogona rakanyorwa zvinotevera maitiro mukana wokuti vanhu vanga :

Fe (TV.) + H2O (g.) + O2 (g) = Fe (OH) 3 (Sol.)

2) richipedza nevhiniga pasoda. moms Vakawanda vanoshandisa ichi kwemakemikari maitiro achigadzirira mukanyiwa zvakasvibirira. Kana ichi chinobviswa pasoda hwakasimba NaHCO3 mu upfu chimiro uye 3% mhinduro kubva acetic asidhi CH3COOH, naizvozvo, asiwo heterogeneous muitiro, sezvo vaviri kuwirirana zvinhu dzakasiyana States of aggregation. Izvi kunorondedzerwa mukana wokuti vanhu vanga:

NaHCO3 + CH3COOH = CH3COONa + H2O + CO2

Ona kuti pano uye maitiro zvigadzirwa vari akasiyana in aggregation - yavaibvisa acetate uye mvura CH3COONa + H2O - iri mvura uye CO2 - ndiye carbon dioxide.

3) Blackening Zvivako dzendarira kana silverware pasi ambient ezvinhu - kuri heterogeneous siyana.

Ndinovimba kuti ikozvino ichi izwi haakonzeri imi chero dambudziko. Uye kana uchine mibvunzo, regai kuva simbe kuvhura bhuku iri kemisitiri kuti giredhi 8 uye kudzokorora zvinhu akafukidzwa zvakare. It kumbobvira anorwadziwa, hazvisi pasina kuti Russian chinoti: "! Kudzokorora - Practice anoita akakwana"
