Kev tshwm sim ntawm magnesium nrog kua qaub
Magnesium hlau dissolves nkag indilute sulfuric acid los tsim cov kev daws teeb meem uas muaj theaquaated Mg (II) ion ua ke nrog hydrogen gas, H2. Cim cov tshuaj tiv thaiv nrog lwm tus kua qaub xws li hydrochloric acid kuj muab cov aquaated Mg (II) ib
Ua raws li qhov kev pom no, cov pa roj dab tsi yog tsim thaum magnesium thiab sulfuric acid react?
hydrogen gas
Kuj Paub, yuav ua li cas thaum magnesium reacts nrog dej kub? Magnesium ( Mg ) Nws reacts qeeb heev nrog dej kub . Nws reacts nrog steam thaum yog cua sov thiab muab hydrogen gas thiab metaloxide.
Yog li ntawd, yuav ua li cas tshwm sim thaum magnesium thiab oxygen react?
Thaum lub magnesium hlau hlawv nws reacts nrog oxygen pom nyob rau hauv cov huab cua tsim Magnesium Oxide . Magnesium muab ob lub electrons rau oxygen atoms toform no cov khoom hmoov. Qhov no yog anxothermic tshuaj tiv thaiv.
Yog magnesium reactive heev?
Magnesium tshwm sim ib txwm tsuas yog incombination nrog rau lwm cov ntsiab lus, qhov twg nws invariably muaj ib lub xeev +2 oxidation. Cov khoom pub dawb (hlau) tuaj yeem tsim tawm, thiab yog heev reactive (txawm hais tias nyob rau hauv lub atmosphere, nws yog sai coated nyob rau hauv ib tug nyias txheej ntawm oxide uas ib nrab inhibits. reactivity - saib passivation).

Thaum cov bicarbonate los ntawm ci sodacomes nyob rau hauv kev sib cuag nrog sulfuric acid tov, nws txais hydrogen ions los ua carbonic acid. Lub seething huab hwm coj ntawm npuas tsim raws li cov pa roj carbon dioxide no khiav tawm ntawm kev daws teeb meem
Yuav ua li cas thaum tooj liab oxide reacts nrog sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Cov roj twg yog tsim thaum dilute hydrochloric acid reacts nrog magnesium carbonate?
Carbon dioxide
