Qab zib dissolves yooj yim hauv dej thiab roj tsis.
Ib yam li ntawd, vim li cas cov piam thaj tsis yaj hauv cov roj?
Vim dej yog polar thiab roj yog nonpolar, lawv cov molecules yog tsis yog attracted rau ib leeg. Cov molecules ntawm polar solvent zoo li dej yog attracted rau lwm cov polar molecules, xws li cov qab zib . Qhov no piav qhia vim li cas qab zib hais tau siab heev solubility hauv dej.
Ib yam li ntawd, roj thiab qab zib tuaj yeem sib xyaw? Qab Zib dissolves yooj yim hauv dej thiab ua oildos tsis yog. Txij li thaum roj tsis soluble hauv dej, nws yuav yeej tsis yaj kiag li. Roj thiab dej yog ib sib tov , tsis yog kev daws teeb meem. Ob hom molecules ( roj thiab dej) tsis sib npaug hauv qhov system.
Tom qab ntawd, ib tug kuj yuav nug, yog qab zib yaj nyob rau hauv vinegar?
Tej zaum koj yuav xav tias txij li thaum koj lub plab muaj cov kua qaub, cov acetic acid nyob rau hauv vinegar yuav tawg los yog yaj khoom qab zib. Qhov tseeb, khoom qab zib tuaj yeem yaj maj mam nyob rau hauv vinegar vim tias cov acetic acid molecules tsis ua yaj qab zib zoo li dej.
Yuav ua li cas yaj?
Kev daws yog tsim thaum ib yam khoom hu ua lub solute " yaj " rau hauv lwm yam khoom hu ua cov kuab tshuaj. Dissolving yog thaum tus solute tawg los ntawm ib tug lojrcrystal ntawm molecules mus rau ntau me me pawg los yog ib tug neeg molecules. Lawv ua Qhov no los ntawm rub tawm cov ions thiab ces nyob ib puag ncig cov ntsev molecules.

Cov pa roj carbon los ntawm qhov twg los tsim cov piam thaj?
Cov pa roj carbon atoms siv los tsim cov carbohydrate molecules los ntawm cov pa roj carbon dioxide, cov roj uas tsiaj exhale nrog txhua qhov pa. Lub voj voog Calvin yog lo lus siv rau cov kev cuam tshuam ntawm photosynthesis uas siv lub zog khaws cia los ntawm lub teeb-dependent kev cuam tshuam los tsim cov piam thaj thiab lwm cov carbohydrate molecules
Cov piam thaj hauv RNA txawv li cas ntawm cov piam thaj hauv DNA?
DNA muaj cov piam thaj deoxyribose, thaum RNA muaj cov piam thaj ribose. Qhov sib txawv ntawm ribose thiab deoxyribose nkaus xwb yog tias ribose muaj ib pawg -OH ntau dua li deoxyribose, uas muaj -H txuas rau qhov thib ob (2') carbon hauv lub nplhaib. DNA yog ob-stranded molecule, thaum RNA yog ib leeg-stranded molecule
Cov piam thaj puas yog cov khoom nruab nrab?
Qab zib tsis yog ib qho acid lossis lub hauv paus. Pure qab zib, los yog qabzib, yog ib qho khoom nruab nrab. Cov khoom nruab nrab yog ib yam khoom uas tsis muaj kua qaub lossis cov khoom siv yooj yim. Neutralsubstances zoo li qab zib tsis ua rau muaj qhov tshwm sim ntawm aLitmus daim ntawv
Cov piam thaj ntau npaum li cas los ntawm photosynthesis hauv ib xyoos?
Hauv ib xyoos Photosynthesis tsim 160 billion tons ntawm carbohydrates
Cov piam thaj yaj li cas hauv tshuaj yej?
Cov suab thaj uas peb siv los ua kom qab zib kas fes lossis tshuaj yej yog cov khoom siv molecular, uas ib tus neeg molecules tuav ua ke los ntawm cov tsis muaj zog intermolecular rog. Qab Zib yaj nyob rau hauv dej vim hais tias lub zog yog muab tawm thaum lub me ntsis polar sucrose molecules tsim intermolecular bonds nrog polar dej molecules
