Carbon dioxide, physico-mankhwala ake katundu ndi mtengo wa

Carbon dioxide, kapena silika - dzina ofanana matanthauzo lodziwika bwino kwa mpweya. Malinga ndi mankhwala gulu, ceni - mpweya okusayidi (IV), NKHA _2. M'mikhalidwe wabwinobwino, pawiri ndi boma gaseous, ndi colorless ndi odorless, koma ali wowawasa kukoma. Sungunuka m'madzi, kupanga carbonic (asidi carbonate). Mbali A mpweya woipa ndi kuti pa kuthamanga yachibadwa mumlengalenga (101325 Pa kapena 760 mamilimita Hg. V.) Kodi kulibe m'moyo madzi, koma mu maonekedwe a mpweya kapena otchedwa ayezi youma. Mpweya madzi angagwe ngati mphamvu kuthamanga. Mu mawonekedwe akhoza kusamutsidwa mu zonenepa ndi kuigwiritsa ntchito pa ena; pakuti kuwotcherera, yopanga zakumwa enaake, kuzizira ndi yozizira mankhwala chakudya, zinthu zozimitsira moto. Nkhanizi ntchito monga usawonongeke ndi E 290, ndi disintegrant ndi refrigerant chifukwa mayeso.

Mpweya woipa - acidic okusayidi, tingathe anatani ndi oxides zikuluzikulu ndi alkalies, potero kupanga mchere - carbonates kapena bicarbonates, ndi madzi. Mkhalidwe anachita kudziwa NKHA ₂ mogwirizana ake ndi hydroxide calcium. Kupezeka kwa mpweya izi zisonyeza turbidity wa njira ndi precipitate. Ena mwa zamchere ndi zitsulo zamchere lapansi (yogwira) ungapsereze mu chikhalidwe cha carbon dioxide, kuwamana iwo za oxygen. Komanso, mpweya amalowa mankhwala anachita ndi M'MALO ndi Kuwonjezera zinthu organic.

Kumachitika mu chikhalidwe ndi mbali ya mpweya envelopu a dziko lapansi. chilengedwe anali olekanitsidwa zamoyo kupuma, ndi zomera kuyamwa izo mu dzuwa ndi ntchito njira thupi ndi amuzolengedwa.

Chifukwa cha mphamvu mkulu kutentha, poyerekeza ndi mpweya wina mumlengalenga, uglikisly mpweya pamene ndende chilengedwe amachititsa kutenthedwa ake, chifukwa m'munsi kutentha madyaidya ndikuledzera mu mlengalenga. A kuwuka mu kutentha kumayambitsa kusungunuka kwa madzi oundana ndipo, monga chotsatira cha kusintha kwa nyengo padziko lapansi. Asayansi amati ponena kuti chisankho cha vutoli (polimbana ndi mmene kutentha) angathandize zomera zobiriwira, okhoza kuyamwa CO2 kwambiri kuposa panopa otayika.

Ngakhale kuti mpweya kumatanthauza kagayidwe wa nyama ndi zomera, kuchuluka wokhutira mu mlengalenga zingachititse kusinza, kufooka, mutu, ndipo ngakhale suffocation. Kupewa hypercapnia m'pofunika ventilate chipinda, makamaka malo kusonkhanitsa ambiri anthu.

Choncho, mpweya woipa - ndi okusayidi asidi amene amapezeka mu chikhalidwe ndi mankhwala a kagayidwe wa nyama ndi zomera. kudzikundikira ake mu mlengalenga ndi choyambitsa mmene kutentha. Mpweya woipa ndi anachita ndi madzi imapanga wosakhazikika asidi carbonic angathe zasintha mu madzi ndi CO2.
