CO2 yog lub cim tshuaj lom neeg rau carbon dioxide. Cov pa roj carbon dioxide ua rau lub suab nrov nrov hauv dej qab zib thiab ntau cov dej cawv, ua rau lub zog ua kom lub khob cij nce ntxiv, cov roj hauv qee cov tshuaj aerosols, thiab cov pa nkev hauv cov tshuaj tua hluav taws. CO2 Nws tuaj yeem tsim ua txhob txwm lossis ua los ntawm cov khoom lag luam ntawm lwm cov tshuaj tiv thaiv kab mob.
Kauj ruam
Ntu 1 ntawm 2: Ua CO2 tom tsev
Kauj Ruam 1. Siv lub raj mis yas 2 litres
Siv lub raj mis yas, tsis yog iav fwj; yog tias koj yuav tsum siv lub zog txaus kom tawg lub raj mis, lub raj mis yas yuav tsis tawg zoo li iav fwj.
Yog tias koj npaj yuav siv CO2 tsim tawm, txhawm rau muab cov pa roj carbon dioxide rau cov nroj tsuag hauv koj lub thoob dej yug ntses, lub raj mis loj no yuav muab khoom txaus rau 25 nkas loos (94.64 litre) thoob dej yug ntses.
Kauj Ruam 2. Ntxiv 2 khob (473. 18 ml) qab zib
Siv cov piam thaj nyoos, tsis yog ua kom qab zib, raws li cov piam thaj ua kom huv yog ua los ntawm cov suab thaj ntau dua, uas yuav ua rau cov poov xab siv sijhawm ntev dua los zom. Ib qho ntxiv, cov piam thaj nyoos kuj tseem pheej yig dua.
Kauj Ruam 3. Siv dej sov, sau lub raj mis mus txog qhov nkhaus ze lub caj dab ntawm lub raj mis
Cov dej sov tuaj yeem siv tau, tab sis dej kub yuav tua cov poov xab.
Kauj Ruam 4. Ntxiv 1/2 teaspoon (2.46 ml) ntawm sodium bicarbonate
Sodium bicarbonate yog cov khoom tseem ceeb hauv ci dej qab zib thiab muaj nyob hauv ntau lub khw.
Kauj Ruam 5. Ntxiv 1/2 teaspoon (2.46 ml) ntawm cov poov xab rho tawm
Yog tias koj muaj cov poov xab rho tawm, nws yuav pab cov poov xab nyob ntev dua.
Ib qho piv txwv ntawm cov poov xab rho tawm yog Vegemite, uas muaj nyob hauv tebchaws Australia. Lwm cov poov xab rho tawm suav nrog Bovril, Cenovis, thiab Marmite
Kauj Ruam 6. Ntxiv 1/3 teaspoon (1.64 ml) ntawm cov poov xab
Brewed poov xab ntev dua li cov poov xab ci. Txawm li cas los xij, ci cov poov xab yog qhov ruaj khov rau cov tshuaj tiv thaiv thiab tsis kim dua li cov poov xab brewed.
Kauj Ruam 7. Kaw lub raj mis kom nruj
Kauj Ruam 8. Co lub raj mis kom sib tov cov poov xab thiab qab zib sib npaug
Koj yuav pom qee qhov ua npuas dej ntawm qhov dej.
Kauj Ruam 9. Qhib lub raj mis
Kauj Ruam 10. Tos 2 txog 12 teev
Cov dej yuav pib ua npuas thaum lub sijhawm no, qhia tias CO2 tab tom tso tawm. Yog tias koj tsis pom npuas tom qab 12 teev, tom qab ntawd koj cov dej kub dhau lossis koj cov poov xab tau ploj mus lawm.
Koj qhov kev daws teeb meem yuav tsum nce mus txog 2 npuas txhua ob. Yog tias muaj npuas ntau dua, koj tuaj yeem rhuav tshem pH ntawm cov dej
Ntu 2 ntawm 2: Lwm Txoj Hauv Kev Los Tsim CO2
Kauj Ruam 1. Ua pa tawm
Koj lub cev siv cov pa uas koj ua pa los cuam tshuam nrog cov protein, fatty acids, thiab carbohydrates uas koj noj. Ib qhov tshwm sim ntawm cov tshuaj tiv thaiv no yog cov pa roj carbon dioxide koj nqus tau.
Hauv kev sib piv, cov nroj tsuag thiab qee hom kab mob siv cov pa roj carbon dioxide los ntawm huab cua thiab, nrog lub zog los ntawm tshav ntuj, ua cov suab thaj yooj yim (piv txwv li carbohydrates)
Kauj Ruam 2. Tua ib yam uas muaj cov pa roj carbon
Lub neej nyob hauv ntiaj teb yog ua raws cov pa roj carbon. Txhawm rau hlawv qee yam, koj xav tau lub txim taws, qhov chaw siv roj, thiab cov cua uas yuav hlawv nws. Cov pa oxygen hauv peb cov cua tau yooj yim cuam tshuam nrog lwm yam tshuaj; muab cov pa tso rau hauv cov pa hlawv, thiab koj tau txais cov pa roj carbon dioxide.
Calcium oxide (CaO), tseem hu ua quicklime, tuaj yeem tsim los ntawm hlawv cov limestone lossis cov txiv qaub nyoos, uas muaj calcium carbonate (CaCO)3). CO2 tso tawm, tawm calcium oxide. (Vim li no, cov tshuaj no tseem hu ua quicklime.)
Kauj Ruam 3. Sib tov cov tshuaj uas muaj cov pa roj carbon
Cov pa roj carbon thiab oxygen ua CO2 pom hauv qee cov tshuaj thiab cov zaub mov cais ua carbonates lossis, yog tias muaj hydrogen, cais ua bicarbonates. Cov tshuaj tiv thaiv nrog lwm cov tshuaj tuaj yeem tso CO2 mus rau saum huab cua lossis sib xyaw nws nrog dej los ua cov pa roj carbonic (H2CO3). Qee qhov tshwm sim tuaj yeem suav nrog:
- Hydrochloric acid (hydrochloric) thiab calcium carbonate. Hydrochloric acid (HCl) yog cov kua qaub nyob hauv tib neeg lub plab. Calcium carbonate (CaCO3) muaj nyob hauv cov pob zeb lim av, cov av nplaum, cov qe, cov hlaws, thiab coral, ntxiv rau hauv qee yam tshuaj tua kab mob. Thaum ob qho tshuaj sib xyaw ua ke, calcium chloride thiab carbonic acid tau tsim, thiab cov kua carbonic tau faib ua dej thiab carbon dioxide.
- Vinegar thiab ci dej qab zib. Vinegar yog ib qho kev daws ntawm acetic acid (C.2H4O2), qhov ci ci yog sodium bicarbonate (NaHCO3). Sib tov ob qhov ua dej, sodium acetate, thiab CO2, feem ntau nyob rau hauv cov tshuaj tiv thaiv ua npuas ncauj.
- Methane thiab dej ua pa. Qhov tshuaj tiv thaiv no tau ua tiav hauv kev lag luam txhawm rau tshem tawm hydrogen siv cov pa ntawm qhov kub siab. Methane (UA4) reacts nrog dej ua pa (H2O) los tsim hydrogen (H2) thiab cov pa roj carbon monoxide (CO), yog cov pa ua rau tuag taus. Cov pa roj carbon monoxide yog tom qab ntawd sib xyaw nrog cov pa dej ntawm qhov kub kom tsim tau ntau cov hydrogen thiab hloov cov pa roj carbon monoxide mus rau cov pa roj carbon zoo dua.
- Poov xab thiab qab zib. Thaum cov poov xab ntxiv rau cov piam thaj hauv cov tshuaj, raws li qhia hauv Tshooj Ib, cov poov xab ua rau cov piam thaj tawg thiab tsim CO.2. Cov tshuaj tiv thaiv no tseem ua rau ethanol (C.2H5OH), ib hom cawv uas pom hauv cov dej cawv. Cov tshuaj tiv thaiv no hu ua fermentation.
