Molar loj ntawm H2SO4 yog 98. Cov lus piav qhia nram qab no H = 1 × 2 = 2, S = 32, O = 16 × 4 = 64 Qhov ntxiv ntawm cov no Yuav muab 98.
Kuj tseem paub yog, MR ntawm h2so4 yog dab tsi?
98,079 g / mol
Ib yam li ntawd, cov qauv h2so4 muab dab tsi? Nws cov tshuaj qauv yog H2SO4 . Nws yog ib qho ntawm cov khoom lag luam tshuaj lom neeg zoo tshaj plaws. Nws ua tau Kev siv cov khoom siv tsis tu ncua, kev tsim cov chiv, roj refining, thiab ntau ntxiv. Sulfuric acid yog ib qho corrosive ntxhia acid siv inlabs, roj teeb, thiab kev tsim khoom.
Ib yam li ntawd, koj tuaj yeem nug, qhov feem pua ntawm h2so4 yog dab tsi?
Ib feem pua ntawm cov khoom
| Element | Cim | Pawg Feem Xyuam |
|---|---|---|
| Hydrogen | H | 2.055% |
| Oxygen | O | 65.251% |
| Sulfur | S | 32.693% |
Muaj pes tsawg atoms nyob rau hauv h2so4?
Ib qho sulfuric ( H2SO4 ) molecule muaj 2 hydrogen atoms , 1 sulfur atom, thiab 4 oxygen atoms . Koj kuj hais ib mole ntawm sulfuric acid muaj ob mols ntawm hydrogen atoms , 1 mol ntawm sulfur atoms , thiab 4 moles ofoxygen atoms . Yog li nyob rau hauv tag nrho, peb muaj 7 mols atoms . Butthas yog nyob rau hauv 1 mol ntawm sulfuric acid.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
