a zoo txhais piv txwv ntawm kev hloov tshuaj .reactants. cov khoom uas tab tom yuav tshwm sim. cov khoom. cov khoom tshiab tsim.
Ib sab ntawm qhov no, dab tsi tuaj yeem siv los qhia txog cov kev hloov pauv uas tshwm sim hauv cov tshuaj tiv thaiv tshuaj?
Kev hloov tshuaj lom neeg
- Hloov hauv Kub. Ib qho kev hloov ntawm qhov kub thiab txias ischaracteristic ntawm kev hloov tshuaj.
- Hloov hauv Xim. Ib qho kev hloov ntawm cov xim kuj yog lwm tus yam ntxwv ntawm cov tshuaj tiv thaiv uas tshwm sim.
- Tsim cov npuas.
Qhov thib ob, thaum lub teeb sib tw yog muab tso rau hauv cawv cov cawv ua rau muaj cua sov thiab lub teeb? Thaum a lit match yog muab tso rau hauv cawv, lub alcoholignites tsim teeb thiab kub . Lub zog nyob rau hauv daim ntawv ntawm hluav taws xob tuaj yeem muab ntxiv rau hauv dej kom sib cais cov dej molecules rau hauv hydrogen gas thiab oxygen gas.
Ua li no, lub sij hawm rau cov tshuaj uas hloov thaum lub sij hawm tshuaj tiv thaiv yog dab tsi?
Ib qho kev hloov ntawm lub cev, xws li kev hloov pauv hauv lub xeev lossis kev ploj, ua tsis tsim ib tug tshiab yam khoom , mas a tshuaj hloov ua . Hauv ib tshuaj tiv thaiv , atoms thiab molecules uas cuam tshuam nrog ib leeg hu ua reactants. Hauv ib tshuaj tiv thaiv , atomsand molecules tsim los ntawm cov tshuaj tiv thaiv yog hu ua cov khoom.
Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no suav nrog ob lossis ntau cov tshuaj sib xyaw ua ke los ua ib qho kev sib xyaw ua ke?
Nyob rau hauv ib tug synthesis tshuaj tiv thaiv , ob lossis ntau yam khoom yooj yim sib xyaw ua ke ib tug tshiab, ntau complex yam khoom . Nyob rau hauv ib tug decomposition tshuaj tiv thaiv , ib complex yam khoom tawg rau hauv ob lossis ntau dua yooj yim dua tshuaj . Hauv ib ib leeg hloov tshuaj tiv thaiv , uncombined element hloov lub caij uas yog ib feem ntawm a compound.
