Hauv txhua pab pawg hlau, reactivity nce thaum koj nqis mus rau pawg. Lub valence electrons tsis nruj nruj thiab yooj yim rau tshem tawm, vim hais tias lawv nyob deb ntawm lub nucleus ntawm lub atom. Ib qho nonmetal nyiam nyiam ntxiv valence electrons kom tau txais lub plhaub valence tag nrho.
Ntawm no, koj ua li cas txiav txim siab tshuaj reactivity?

Dab tsi yog txhais los ntawm chemical reactivity? Tshuaj reactivity yog tus nyiam ntawm ib yam khoom mus rau undergo tshuaj hloov hauv ib qho system. Cov tshuaj reactivity worksheet muaj ib tug zoo heev database ntawm reactivity rau ntau tshaj 4,000 yam muaj kev phom sij tshuaj . Txawm li cas los xij, lub reactivity kuj txhais tau tias tshuaj khoom.
Tsis tas li ntawd, puas yog reactivity yog cov cuab yeej tshuaj?
Cov khoom siv tshuaj yog khoom uas tuaj yeem ntsuas lossis pom tsuas yog thaum teeb meem hloov pauv los ua qhov sib txawv kiag li. Lawv suav nrog reactivity , flammability, thiab muaj peev xwm los xeb. Reactivity yog lub peev xwm ntawm cov teeb meem los ua tshuaj lom neeg nrog rau lwm yam tshuaj.
Ib co piv txwv ntawm reactivity yog dab tsi?
Piv txwv ntawm chemical reactivity suav nrog kev sib xyaw ua ke los ua cov tshuaj thiab sib xyaw cov tshuaj lom lom nrog cov tshuaj nyob rau hauv ib puag ncig cuam tshuam.

Koj yuav xam cov qauv tshuaj li cas?
Faib cov molar mass ntawm lub compound los ntawm cov empirical formula mass. Cov txiaj ntsig yuav tsum yog tus lej tag nrho lossis ze rau tag nrho tus lej. Muab tag nrho cov subscripts nyob rau hauv cov qauv empirical los ntawm tag nrho cov naj npawb pom nyob rau hauv kauj ruam 2. Qhov tshwm sim yog cov qauv molecular
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Yuav ua li cas koj xam tus nqi ntawm cov kuab tshuaj kom yaj?
Solubility qhia qhov siab tshaj plaws ntawm cov khoom uas tuaj yeem yaj hauv cov kuab tshuaj ntawm qhov kub thiab txias. Xws li kev daws yog hu ua saturated. Faib qhov loj ntawm qhov sib xyaw los ntawm qhov hnyav ntawm qhov hnyav thiab muab 100 g los xam cov solubility hauv g / 100g
Yuav ua li cas koj xam cov cua siab hauv cov yeeb nkab?
Xam qhov poob siab ntawm 100 feet ntawm cov yeeb nkab, vim qhov no yog li cas cov yeeb nkab ntws cov ntaub ntawv nthuav tawm. 135 psi minus 112-psi = 23-psi / 350/100 = 6.57-psi poob rau 100-feet. Raws li 6.57psi tsawg dua 6.75 psi, qhov piv txwv no nyob hauv 'kev ua tau zoo' thaj tsam
Yuav ua li cas koj txiav txim siab reactivity?
Tus naj npawb ntawm electrons nyob rau hauv lub plhaub sab nraud ntawm ib lub atom txiav txim siab nws cov reactivity. Noble gases muaj tsawg reactivity vim lawv muaj tag nrho cov electron plhaub. Halogens yog cov reactive heev vim lawv nkag tau ib qho hluav taws xob los sau lawv lub plhaub sab nraud
