Ukuhlolwa ekhaya kwamakhemikhali amancane

Izivivinyo ekhaya, esizoxoxa ngazo manje, zilula, kodwa zijabulisa kakhulu. Uma ingane yakho isanda nje ukujwayela uhlobo lwezinto ezihlukahlukene nezinqubo, okuhlangenwe nakho okunjalo kuzobukeka njengomlingo wangempela kuye. Kodwa akuyona imfihlo kunoma ubani ukuthi kungcono ukuveza ulwazi oluyinkimbinkimbi kubantwana ngesimo semdlalo - lokhu kuzosiza ukulungisa imininingwane bese ushiya izinkumbulo ezicacile ezizosiza ekuqeqesheni okuqhubekayo.

Ukuqhuma emanzini athule

Ukuxoxa ngezivivinyo ezingenzeka ekhaya, okokuqala sizokutshela ukuthi singenza kanjani ukuqhuma okuncane. Uzodinga isitsha esikhulu esinezimpompo ezijwayelekile (isibonelo, kungaba ibhodlela lamathathu amathathu). Kuyinto efiselekayo ukuthi uketshezi lushiywe endaweni enokuthula izinsuku ezingu-1-3. Emva kwalokho, ngokucophelela, ngaphandle kokuthinta umkhumbi ngokwawo, uphonsa amaconsi ambalwa eyinki emkhatsini wamanzi kusukela phezulu. Zizohamba kahle emanzini, njengokungathi zidubula kancane kancane.

Ibhaluni lomoya elizifakazela lona

Lesi esinye isipiliyoni esithakazelisayo esingenziwa ngokuqhuba ukuhlolwa kwamakhemikhali ekhaya. Kulo ibhola ngokwayo kudingeke ukuba uthele isipuni se-soda evamile yokubhaka. Okulandelayo, udinga ukuthatha ibhodlela lepulasitiki elingenalutho bese uthele kuwo izipuni ezine zeviniga. Ibhola kumele lihanjiswe entanyeni yalo. Ngenxa yalokho, i-soda izothululwa kuviniga, kuzokwenzeka lapho kukhishwa i-carbon dioxide, futhi ibhaluni lizovunywa.

I-volcano

Ngosizo lwe-soda kanye neviniga efanayo, ungenza intaba-mlilo yangempela endlini yakho! Njengesizathu, ungasebenzisa ngisho indebe yepulasitiki. "Emagumbini" alala amapuni amabili we-soda, uthele ingxenye yesigamu seglasi lamanzi afudumele bese wengeza umbala omncane wokudla wombala omnyama. Khona-ke kuyoba nje ukwengeza ingxenye yesigila seviniga bese ubheka "ukuqhuma."

"Umbala" womlingo

Ukuhlola ekhaya ongayibonisa ingane yakho kufaka phakathi nezinguquko ezingavamile ezintweni ezihlukahlukene zombala wazo. Isibonelo esicacile salokhu ukuphendula okwenzeka lapho i-iodine nesitashi zihlanganiswa. Ukuxuba i-iodine ensundu nesitashi esimhlophe, uthola uketshezi ... i-hue eluhlaza okwesibhakabhaka!

Umlilo

Yini enye ongayenza ukuhlolwa ekhaya? I-Chemistry inikeza insimu enkulu yemisebenzi kulokhu. Isibonelo, ungenza iziqhumane ezikhanyayo ngaphakathi egumbini (kodwa kungcono egcekeni). I-potassium permanganate encane kufanele icutshungulwe ibe yi-powder ecolekileyo, bese ithatha inani elifanayo lemali futhi igaxe. Ukuxuba ngokugcwele amalahle nama-manganese, sinezela lapho i-powder yensimbi. Le nhlanganisela ithululelwa kwisikhumba sensimbi (i-thimble ejwayelekile) futhi igcine ilangabi lomlilo. Lapho nje ukushiswa kushisa, imvula yonke yezinhlanzi ezinhle izoqala ukuqhuma nxazonke.

I-soda rocket

Futhi, ekugcineni, sizophinde sisho mayelana nokuhlolwa kwamakhemikhali ekhaya, lapho kutholakala khona ama-reagents elula futhi atholakalayo-uviniga ne-sodium hydrogencarbonate-ezibandakanya. Kulesi simo, udinga ukuthatha ikhasethi yeplastiki yefilimu, uyigcwalise nge-baking soda, bese-uthele ngokushesha emathisipuni amabili eviniga. Esikhathini esilandelayo, uvale ikhava ye-rocket eyenziwe ngokwakho, uyibeke emhlabathini phansi, uphindele emuva bese ubukela indlela esusa ngayo.
