Waayo-aragnimo Kiimikada - Mount Vesuvius miiska

Sidee ku qaataan cashar xiiso in kiimikada jikada oo aad u ammaan ah oo xiiso leh ilmahaaga? Waxaan isku dayaan in ay qabtaan aragnimo kiimikada dhabta ah - Volcano ee saxan miis si joogto ah. Waayo-aragnimo this, waxaad u baahan tahay qalabka soo socda iyo kiimikada:

- gabal dhoobo ah (ka waxaan ka dhigi doonaa volcano laftiisa);

- saxan;

- acetic acid,

- baking soda,

- dareere weelka;

- dheeh.

Qaybaha kor ku xusan si fudud loo heli karaa guriga kasta ama waaxda dhaqaalaha ee dukaan dhow. Waxay arrin ammaan yihiin, laakiin sida wax tijaabo ah ee kiimikada, taas oo sidoo kale u baahan doonaa waafaqsan xeerarka ammaanka.

1. Plasticine oo waxaad ka samaysaa salka koorta volcano leh oo god ah. iyaga Connect qarkiisa si taxadar leh dharbaaxay. Waxaan aad u hesho plasticine qaabka volcano in dhaadhacyadii. size Inner of our design waa in ay leeyihiin goobo ballaciisu yahay ee ku saabsan 100 - 200 mm. Ka hor inta ku rakibidda khariidad ku saxan ama saxaarad hubi our volcano on dillaac ah, Oo waxaan ka soo ururiyaan biyo iyo u aragto haddii ay u gudbinayaa. Haddii wax walba eey fiican - dhigay khariidad ee volcano ee ahaa wasladdii.
2. Waxaan hadda guurto on in ay qaybta xigta - karinta dhagax dab. Waxaan hurudo in our volcano tijaabada ahayd dhoobo hal qaado oo baking soda, weelka dareere ah ee mugga la mid ah oo dheeh ah in wasakheeyey qarax mustaqbalka ee dhagax dab in midabka dhiganta dhabta ah. Si loo gaaro isku mid ah ugu badnaan, waxaad isticmaali kartaa midabaynta cuntada, rinjiga carruurta si rinjiga iyo xataa juice baytaraafka caadiga ah. kiimikada Tani waa si cilinta-aragnimo ah ee ilmaha oo indhihiisa in qarax ka Kobenhagen ee dabiiciga ah.
3. Si aad u bilowdo qarax waa lagama maarmaan si ay u buuxiyaan bohol-afraad ee koob oo khal. Inta lagu jiro reaction kiimikada xarunta a of soda iyo acetic acid keenaysaa in formation of cusbada of acid carbonic, taasoo la xiriirta xeryahooda ku degganayn oo markiiba decomposes biyaha iyo carbon dioxide. Waa habkan of xumbo iyo ku siin our view of qarax ee volcano la socodka dhagax dab on dalcadaha ah. waayo-aragnimo Chemical dhamaystiran.

Tusidda volcano firfircoon dugsiga

Waxa intaa dheer in nooca kor ku tilmaamay of tusidda qarax ammaan, waxaa weli jira siyaabo badan si ay u helaan volcano ee miiska saaran. Laakiin tijaabo kuwaas waxaa sida ugu wanaagsan sameeyo in a dhismaha si gaar ah loo diyaariyey - laboratories chemistry dugsiga. The ugu fiican u yaqaan in ay dhan at Volcano dugsiga Boettger. Waayo, anshaxa ayaa loo baahan yahay dichromate ammonium, taas oo loo daadshay buur, ugu sareysa ee ay fasaxa. bohol waxaa la dhigayaa gabal cudbi lagu qooyay khamri, kaas oo u gubta. Inta lagu guda jiro dareen ah nitrogen, biyo iyo xabagta chromium. dareen-celin ka soo baxa aad uula mid tahay qarax ee volcano firfircoon.

Si uu korka, iyo sidoo kale horumarinta deeq waxbarasho ee carruurta si fiican u xiran by tijaabo kiimikada leh qaar ka mid ah tusaale ahaan-ugu wanaagsan ee loo yaqaan of qarax ee taariikhda ilbaxnimada aadanaha, tusaale ahaan, la qaraxa ee Mount Vesuvius ee Italy, gaar ahaan, sababta oo ah mid yaab leh oo faa'iido u ah bidhaamayaan loo qeexi karaa by udaabacida ee weyn rinjiyeynta Karla Bryullova "Maalmihii la soo dhaafay of lana kulmay" (1827-1833 sannad xisaabeedka).

Aan xiisaha carruurta sidoo kale jiri doona sheekada volcanologist halkii dhif iyo abaalmarin ah oo xirfad. Xirfadlayaalkaani waxay si joogto ah ula socdaan hore u bakhtiyeen iyo marno firfircoon maanta, ka dhigi fikrado ku saabsan waqtiga ay suurtogal tahay iyo xoog of Mandheera mustaqbalka.
