Yuav ua li cas Tshuav Mg + H2O = MgO + H2 | Magnesium + Dej ( chav )
Hauv qhov no, yuav ua li cas thaum magnesium reacts nrog chav?
Magnesium hlawv hauv chav tsim cov dawb magnesium oxide thiab hydrogen gas. Tom qab ob peb feeb, ib co npuas ntawm hydrogen daim ntawv ntawm nws nto, thiab lub coil ntawm magnesium ribbon feem ntau ntab rau saum npoo.
Tsis tas li ntawd, magnesium puas cuam tshuam nrog chav? Magnesium ua tsis yog teb nrog dej rau txhua qhov tseem ceeb. Magnesium hlau ua txawm li cas los xij react nrog chav muab magnesium oxide (MgO) (los yog magnesium hydroxide, Mg (OH)2, nrog tshaj chav thiab hydrogen gas (H2).
Tsis tas li ntawd, qhov sib npaug ntawm magnesium thiab dej yog dab tsi?
Magnesium feem ntau yog tam sim no Mg 2+ (aq) hauv cov dej daws, tab sis kuj yog MgOH+ (aq) thiab Mg (OH)2 (aq). Hauv dej hiav txwv nws kuj tuaj yeem pom zoo li MgSO4. Dej solubility ntawm magnesium hydroxide yog 12 mg /L.
Dab tsi yog qhov sib npaug tshuaj rau chav?
Chav yog qhov tseem ceeb dej nyob rau hauv lub xeev zoo li gas. So dej thiab yog li no steam, lub npe tsim nyog yog dihydrogen monoxide , yuav muaj lub forumla H2O.

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 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 qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
