Piv txwv ntawm tshuaj muaj zog suav nrog flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, rau piv txwv , ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2).
Tib neeg kuj nug, 4 piv txwv ntawm cov khoom siv tshuaj lom neeg yog dab tsi?
Nov yog qee qhov piv txwv ntawm cov khoom siv tshuaj lom neeg:
- Reactivity nrog lwm yam tshuaj.
- Toxicity.
- Coordination tooj.
- Flammability.
- Enthalpy ntawm kev tsim.
- Kub ntawm combustion.
- Oxidation xeev.
- Tshuaj stability.
Tsis tas li ntawd, 10 cov piv txwv hloov tshuaj lom neeg yog dab tsi? Kaum piv txwv ntawm kev hloov tshuaj lom neeg yog:
- Hlawv cov thee, ntoo, ntawv, kerosene, thiab lwm yam.
- Tsim cov curd los ntawm mis nyuj.
- Electrolysis ntawm dej los tsim hydrogen thiab oxygen.
- Rusting ntawm hlau.
- Kev tawg ntawm cracker.
- Ua noj ua haus.
- Kev zom zaub mov.
- Germination ntawm noob.
Ib yam li ntawd ib tug yuav nug, dab tsi yog suav hais tias yog tshuaj lom neeg?
A chemical khoom yog ib yam ntawm cov khoom khoom uas yuav tshwm sim thaum lub sij hawm, los yog tom qab, a tshuaj tshuaj tiv thaiv; uas yog, txhua yam zoo uas tuaj yeem tsim los ntawm kev hloov cov khoom siv xwb tshuaj tus kheej. Lawv kuj tuaj yeem pab tau los txheeb xyuas cov khoom tsis paub lossis cais lossis ntxuav nws ntawm lwm yam khoom.
Muaj pes tsawg cov tshuaj muaj pes tsawg leeg?
Nyob ntawd yog ntau yam tshuaj ntawm qhov teeb meem. Hauv ntxiv rau toxicity, flammability, tshuaj stability, thiab oxidation xeev, lwm yam tshuaj muaj zog suav nrog: Enthalpy ntawm kev tsim. Qhov kub ntawm combustion.
