A balanced nuclear equation yog ib qhov twg cov lej ntawm cov lej loj (tus lej saum toj kawg nkaus hauv qhov cim) thiab cov lej ntawm cov lej atomic tshuav nyiaj li cas ntawm ob sab ntawm ib qho kev sib npaug . Nuclear equation teeb meem feem ntau yuav muab xws li ib tug hais yog ploj lawm.
Ntawm no, 4 hom kev tawm tsam nuclear yog dab tsi?
Plaub hom tshuaj tiv thaiv tseem ceeb uas yuav tau them rau hauv chav tsev no yog:
- Fission.
- fusion.
- Nuclear Decay.
- Kev hloov pauv.
Kuj Paub, dab tsi yog lub cim rau beta particle? A beta particle , kuj hu beta ray lub beta hluav taws xob ( cim b ), yog lub zog siab, siab ceev electron lossis positron tawm los ntawm cov xov tooj cua lwj ntawm lub atomic nucleus thaum lub sij hawm tus txheej txheem ntawm beta lwj . Muaj ob hom ntawm beta lwj , ua β − lwj thiab ua β + lwj , uas tsim electrons thiab positrons feem.
Kuj Paub, ob txoj cai tswj kev sib npaug ntawm cov tshuaj tiv thaiv nuclear yog dab tsi?
Nuclear tshuaj tiv thaiv kuj ua raws li txoj cai kev txuag, thiab lawv sib npaug hauv ob Txoj kev: Cov lej ntawm cov lej loj ntawm cov reactants sib npaug ntawm cov lej ntawm cov khoom. Tus lej ntawm cov nqi ntawm cov reactants sib npaug ntawm cov nqi ntawm cov khoom.
Lwm lub npe rau beta rho tawm yog dab tsi?
Teb: Lwm lub npe rau beta - rho tawm particle yog electron. Kev piav qhia: Beta - rho tawm particle . yog tso tawm thaum lub sij hawm beta - rho tawm lwj cov tshuaj tiv thaiv nuclear.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?
Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
