Stoichiometry yog hais txog kev sib raug zoo ntawm qhov ntau ntawm cov reactants thiab cov khoom ua ntej, thaum lub sij hawm, thiab ua raws li cov tshuaj tiv thaiv.
Dab tsi yog qhov txhais zoo tshaj ntawm stoichiometry?
1: ib ceg ntawm chemistry uas cuam tshuam nrog kev siv cov cai ntawm cov kev faib ua feem thiab kev txuag ntawm huab hwm coj thiab lub zog rau cov tshuaj lom neeg. 2a: kev sib raug zoo ntawm cov khoom siv hauv cov tshuaj lom neeg.
Stoichiometry hauv chemistry yog dab tsi?
Stoichiometry yog raws nraim li ntawd. Nws yog qhov kev sib raug zoo ntawm tus lej ntawm moles (thiab yog li qhov loj) ntawm ntau yam khoom thiab cov tshuaj reactants hauv cov tshuaj tiv thaiv tshuajCov tshuaj tiv thaiv tshuaj yuav tsum sib npaug, lossis ua lwm yam lus, yuav tsum muaj tib yam ntawm ntau yam atoms hauv cov khoom xws li hauv cov reactants.
piv txwv ntawm stoichiometry yog dab tsi?
Stoichiometry yog thaj chaw ntawm chemistry uas cuam tshuam nrog cov txheeb ze ntawm cov tshuaj reactants thiab cov khoom lag luam hauv cov tshuaj tiv thaiv. Piv txwv li, thaum oxygen thiab hydrogen react los tsim dej, ib mole ntawm oxygen reacts nrog ob moles ntawm hydrogen los tsim ob moles ntawm dej. …
Stoichiometry hauv chemistry chav kawm 11 yog dab tsi?
Hint: Stoichiometry yog qhov ntsuas ntawm cov nqi ntawm cov reactants thiab cov khoom uas koom nrog cov tshuaj tiv thaiv tshuaj lossis tsim. Nws yog tus txheeb ze tus nqi ntawm reactant thiab khoom.
