Ntuj roj yog tsim ntawm plaub hydrogen atoms thiab ib tug carbon atom (CH4 los yog methane). Tsis muaj xim thiab tsw ntxhiab hauv nws ntuj xeev, natural gas yog qhov huv tshaj plaws hlawv cov pob txha. Thaum nws hlawv, natural gas feem ntau tsim cov pa roj carbon dioxide, dej vapor thiab me me ntawm nitrogen oxides.
Ib yam li ntawd, dab tsi yog natural gas thiab nws muaj pes tsawg leeg?
Ntuj roj (tseem hu ua fossil gas ) yog ib txwm tshwm sim hydrocarbon gas sib tov muaj feem ntau ntawm methane, tab sis feem ntau suav nrog ntau qhov sib txawv ntawm lwm cov alkanes siab dua, thiab qee zaum tsawg feem pua ntawm carbon dioxide, nitrogen, hydrogen sulfide, los yog helium.
Tsis tas li ntawd, dab tsi ua rau 90% ntawm natural gas? Ntuj roj yog ua nce ntawm ib tug sib tov ntawm plaub ib txwm tshwm sim cov pa , txhua yam uas muaj cov qauv molecular sib txawv. Qhov sib tov no feem ntau yog methane, uas ua rau 70- 90 % ntawm natural gas nrog rau ethane, butane thiab propane.
Hais txog qhov no, dab tsi yog natural gas?
Ntuj roj yog a roj qhov chaw muaj feem ntau ntawm methane. Nws feem ntau pom muaj cuam tshuam nrog lwm cov fossil fuels, hauv coal txaj, xws li methane clathrates, thiab yog ib txwm tsim nyob rau hauv a Cov txheej txheem lom neeg los ntawm "cov kab mob methanogenic" hauv ib puag ncig xws li bogs, av-fills thiab marshes.
Dab tsi yog cov piv txwv ntawm natural gas?
Dej, ethane, butane, propane, pentanes, hydrogen sulphide, carbon dioxide, dej vapor, thiab qee zaus helium thiab nitrogen tej zaum yuav muaj nyob rau hauv ib tug natural gas. Yuav kom siv tau rau lub zog, lub methane yog ua tiav thiab sib cais los ntawm lwm cov khoom.

Puas yog Southwest Gas Natural Gas?
Southwest Gas Corporation muab kev pabcuam roj av rau ntau dua 1.8 lab tus neeg nyob hauv, kev lag luam thiab kev lag luam nyob hauv Arizona, California, thiab Nevada
Dab tsi yog Natural Resource Txhais Lus & Hom?
Cov peev txheej ntuj tuaj yeem txhais tau tias yog cov peev txheej uas muaj nyob (hauv ntiaj teb) ywj pheej ntawm tib neeg kev ua. Cov piv txwv ntawm cov peev txheej ntuj muaj xws li huab cua, hnub ci, dej, av, pob zeb, nroj tsuag, tsiaj txhu, thiab fossil fuels
Lub zog molecule ntawm cell hu ua worksheet yog dab tsi?
Cov Lus Qhia: Kho koj daim ntawv ua haujlwm siv tus yuam sij no. Siv cov xim sib txawv los ua kom koj kho. Adenosine triphosphate yog lub zog molecule siv los ntawm txhua lub hlwb los ua haujlwm thiab ua haujlwm
Dab tsi tuaj yeem cuam tshuam cov duab ntawm cov enzyme molecule?
Cov protein hloov pauv zoo li qhov kub thiab txias. Vim tias ntau ntawm cov enzymes ua haujlwm raws li nws cov duab, qhov kub thiab txias tuaj yeem cuam tshuam cov txheej txheem thiab cov enzyme yuav tsis ua haujlwm. Qib pH: Lub acidity ntawm ib puag ncig hloov cov duab ntawm cov protein nyob rau hauv tib txoj kev uas kub ua
Dab tsi yog qhov chaw ntawm phospholipid molecule?
Phospholipids muaj glycerol molecule, ob fatty acids, thiab ib pawg phosphate uas hloov los ntawm ib qho cawv. Cov pab pawg phosphate yog qhov tsis zoo-them lub taub hau polar, uas yog hydrophilic. Cov kab mob fatty acid yog cov uas tsis muaj roj, tsis muaj polar tails, uas yog hydrophobic
