Izenzakalo Chemical kubomi bemihla ngemihla

Ihlabathi elisingqongileyo, ndawonye bonke ubutyebi kunye neyantlukwano yayo, uhlala ngokunxulumene nemithetho ekulula ngobulungisa ukucacisa ngoncedo Sciences ezifana zemvelo chemistry. Kwaye nkqu iziseko ebomini kumzimba ezintsonkothileyo njengomntu, akukho nto kodwa nesenzeko imichiza kunye neenkqubo.

Iingcaciso kunye nemizekelo

Umzekelo lokugcina - iti, babeka phezu komlilo. Emva kwexesha amanzi iqala akakhululeki, ngoko ibile. Siva hi ukusuka iketile Ibhotile iya kumka Jets ngomphunga. Wayevela phi, kuba esityeni kwakungelula ekuqaleni! Ewe, kodwa ke amanzi kwiqondo elithile, iqalisa ukutshaza ibe gas, litshintsha imo wayo wenyama ulwelo nerhasi. ie yena wayeyedwa amanzi efanayo, kodwa ngoku ngohlobo zomphunga. Le isenzeko emzimbeni.

A nesenzeko imichiza, siza kubona ukuba siwisa emanzini abilayo ingxowa yeti nokupheka. Amanzi esipilini okanye esinye isitya, zipeyintwe bomvu brown. Zemichiza reaction liya kwenzeka; ngenxa amagqabi eti ubushushu zaparivatsya kwanokuqaqambisa zombala umbala kunye incasa semvelo kwisityalo. Sifumana into entsha - ukusela ethile, abayinqobo kuphela kuye iimpawu esemgangathweni. Ukuba kukho ukudibanisa iglu ezimbalwa iswekile, oko iyachithakala (Ngumzimba), kwaye iti kuya kuba mnandi (imichiza reaction). Ngoko ke, lo ophathekayo nemichiza badla zinxibelelene kwaye lixhomekeke kwelinye. Umzekelo, ukuba isingxobo iti ibekwa emanzini abandayo, basabela kungenzeki, amagqabi eti namanzi aziyi kusebenza, kunye neswekile ukunyibilika kakhulu engasafuni.

Ngenxa yoko, inkqubo yemichiza - zezo apho kwezinye izinto bayaguquka kwezinye (emanzini-in-iti, amanzi kwi isiraphu, iinkuni uthuthu, njalo njalo) enye ngumkhuba imichiza ekuthiwa imichiza reaction.

Ebizwa ngumkhuba emzimbeni apho ekwakhiweni eekhemikhali umbandela uhlala kuso, litshintsha imo ngokwasemzimbeni, ubungakanani umzimba, imilo, njl (Amanzi Isilima intwasahlobo, engumkhenkce zibe ngumkhenkce, isebe lomthi, kwaphulwa kwisiqingatha).

Imigaqo ingenzeka zidlule

Kwi nokuba iikhemikhali kunye ophathekayo kwenzeka, sinako kugweba ngemiqondiso ezithile kunye notshintsho ukuba kwenzeka umzimba ethile okanye isiyobisi. Ngaloo ndlela, uninzi ekudibaneni kwemichiza kukhatshwa i 'lweempawu' zilandelayo:

• ngenxa okanye kwenze kwi flow ezinjalo;
• inguqu kweziyobisi umbala;
• uyakwazi ukhululiwe igesi, umzekelo, carbon monoxide ngexesha omlilo;
• Absorption kwenzeka, okanye icala, ukukhululwa ubushushu;
• wokunciphisa kunokwenzeka lokukhanya.

Isimo yamachiza ziye zaphawulwa, ie, basabela kwenzeke, kufuneka ezinye iimeko:

• i reactants kufuneka ukunxibelelana, kunye namanye ukuba zoqhagamshelwano (ngamanye amazwi, kufuneka enye ukuba athele amagqabi eti indebe yodwa yamanzi ashushu);
• into ukusilwa ngcono, ngoko ke indlela iya kuqhubeka ngokukhawuleza msinyane intsebenziswano (iswekile ngokukhawuleza zichithakala nje, Inyibilikile amanzi ashushu ngaphezu lunamahlwili amhlophe);
• ukusabela ezininzi Inokwenzeka kufuneka ukutshintsha kolawulo iqondo lobushushu reactants, ukupholisa okanye amalahle ukuze kwiqondo elithile.

Qwalasela izenzakalo ngamachiza ibe empirically. Kodwa ukuyichazela ephepheni kungenziwa imichiza equation (equation imichiza reaction).

Ezinye zezi meko kunye nomsebenzi ngenxa ukuvela kwezi ophathekayo, ezifana ubushushu, okanye izinto ukudibana ngqo, imizimba phakathi kwabo. Umzekelo, ukuba hit ngokwaneleyo nzima ngehamile phezu kwentloko isikhonkwane, oko gqitha ukuphelelwa imilo yayo yesiqhelo. Kodwa oko kuya kuhlala khona intloko isikhonkwane. Kungenjalo, xa ibhalbhu kwi womnatha, filament Tungsten ngaphakathi iqala ukuba nehlombe evutha. Noko ke, into obenosinga yenziwa apho, yaye uya kuhlala Tungsten efanayo.

Inkcazelo iinkqubo ngokwasemzimbeni ngezimanga kwenzeka ngokusebenzisa ifomula emzimbeni, zokusombulula iingxaki emzimbeni.
