Ib txoj hauv kev los mus ua kom xam cov kev lag luam atom yog siv cov kauj ruam hauv qab no:

  1. Tsim ib qho tshuaj kev sib npaug rau qhov muab tshuaj tiv thaiv.
  2. Balance cov kev sib npaug .
  3. xam qhov loj ntawm reactants thiab cov khoom siv atomic masses thiab formula masses los ntawm lub periodic table.
  4. xam qhov feem pua atom kev lag luam .

Ib yam li ib tug yuav nug, Atom kev lag luam hauv ntsuab chemistry yog dab tsi?

Ntsuab Chemistry Txoj Cai: Atom Economy . Atom kev lag luam txhais tau hais tias ua kom muaj kev sib koom ua ke ntawm cov khoom siv los ntawm cov khoom pib lossis cov tshuaj reagents rau hauv cov khoom kawg. Nws yog qhov tseem ceeb tiv thaiv kev ua qias tuaj ntawm qib molecular.

Ib yam li ntawd, qhov sib npaug rau moles yog dab tsi? Piv txwv ua haujlwm: moles = mass ÷ molar loj (n=m/M) Xam cov pa oxygen, O2, nyob rau hauv moles tam sim no nyob rau hauv 124.5 g ntawm oxygen gas.

Xav txog qhov no, koj puas suav nrog coefficients hauv atom kev lag luam?

Atom kev lag luam txhais tau tias yog qhov quotient ntawm cov txheeb ze molecular loj ntawm cov khoom xav tau los ntawm cov txheeb ze molecular loj ntawm tag nrho cov reactants. Ib yam li ntawd, lwm yam coefficients nyob rau hauv chemical equation yuav yuav tsum tau coj mus rau hauv tus account.

Atom Economy yooj yim txhais yog dab tsi?

Atom kev lag luam ( atom efficiency / feem pua) yog kev hloov dua siab tshiab ntawm cov txheej txheem tshuaj nyob rau hauv tag nrho cov atoms koom nrog thiab cov khoom xav tau tsim.
