Bond Strength and Acids Lub zog ntawm cov kua qaub feem ntau nyob ntawm qhov loj ntawm 'A' atom: qhov me dua 'A' atom, qhov muaj zog H-A daim ntawv cog lus. Thaum nkag mus rau hauv kab hauv Lub Sijhawm Teem Sijhawm (saib daim duab hauv qab), cov atoms tau loj dua yog li lub zog ntawm daim ntawv cog lus tsis muaj zog, uas txhais tau hais tias cov kua qaub muaj zog dua.
Koj ua li cas txiav txim siab qhov kev txiav txim ntawm cov kua qaub zog?
Yog li ntawd, qhov tseeb ntawm acidity yog D > C > B > A. Li no, qhov kev xaiv raug yog (B).
Dab tsi yog cov kua qaub uas muaj zog tshaj plaws nyob rau hauv kev txiav txim?
Cov kua qaub muaj zog yog hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, thiab chloric acid.
Koj ua li cas cov tebchaw kom nce acidity?
Kev txiav txim ntawm acidity, mus ntawm sab laug mus rau sab xis (nrog 1 yog acidic tshaj), yog 2-1-4-3. Qhov tsawg tshaj plaws acidic compound (thib ob ntawm sab xis) tsis muaj phenol pawg - aldehydes tsis acidic.
Yuav ua li cas nce lub zog ntawm cov kua qaub?
Qhov nce hauv acid zog nrog nce tus naj npawb ntawm cov pa oxygen atomsyog vim ob qho tib si cov nyhuv inductive thiab nce stabilization ntawm conjugate puag. … Qhov txo qis hauv electron ceev hauv O–H daim ntawv cog lus ua rau nws tsis muaj zog, ua rau nws yooj yim dua kom plam hydrogen li H + ions, yog li ua kom lub zog ntawm cov kua qaub.

Ntsuas ntsuas ntsuas ntsuas dab tsi?
Speedometer, ntsuas uas qhia tias kev ceev ntawm lub tsheb, feem ntau ua ke nrog cov cuab yeej hu ua odometer uas teev qhov kev ncua deb. Lub ntsuas ntsuas ntsuas ntsuas lub cev yog dab tsi? Lub ntsuas nrawm ntawm lub tsheb nthuav tawm cov ntaub ntawv hais txog qhov nrawm nrawm ntawm koj lub tsheb.
Yuav ua li cas kom cov kua qaub hypochlorous?
Cov chemistry tom qab ua Hypochlorous yog qhov paub zoo: cov txheej txheem electrolytic lov cov dej ntsev (H 2 O + NaCl) nqes mus rau hauv cov ntsiab lus tseem ceeb ua ntej Cov tshuaj tiv thaiv oxidises ntawm qhov zoo them anode. Cov tshuaj tiv thaiv tso tawm cov tshuaj chlorine hauv cov txheej txheem uas dhau los ua Hypochlorous acid, ntawm pH txoj cai.
Lub sijhawm vaporization cov kua ua kua nce zog?
VAPORIZATION Thaum dej nce mus txog qhov kub ntawm 100ºC, cov dej molecules txav nrawm heev uas lawv tawg tawm ntawm cov chaw nyiam uas tuav lawv ua ke hauv cov kua dej. … CONDENSATION Thaum cov chav txias txias, nws tso lub zog thermal thiab hloov mus rau hauv nws lub xeev ua kua.
Thaum lub sijhawm ntsuas kev ntsuas thawj zaug yog ntsuas los ntawm kev ntsuas?
Thaum qhov kev ntsuam xyuas thawj zaug, kev ncig yog ntsuas los ntawm kev ntsuam xyuas: pulse zoo, los ntshav sab nraud, thiab tawv nqaij. Yuav ntsuas dab tsi thaum lub sijhawm ntsuas thawj? rau qhov ntawm qhov kev ntsuam xyuas thawj zaug yog:
Cov ntsuas olfactory qhia li cas cov kua qaub thiab cov hauv paus?
Ib qho taw qhia olfactory ua haujlwm ntawm lub hauv paus ntsiab lus tias thaum muaj kua qaub lossis lub hauv paus ntxiv rau nws, ces cov ntxhiab tsw txawv tuaj yeem kuaj pom hauv cov hauv paus whereastsw tsw zoo ib yam hauv cov kua qaub. Qee yam tshuaj uas hloov nws cov ntxhiab hauv Acidic lossis nruab nrab nruab nrab.
