Rau tshuav K + O2 = K2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug. Thaum koj paub ntau npaum li cas ntawm txhua hom atom koj tuaj yeem hloov pauv cov coefficients (tus lej nyob rau pem hauv ntej ntawm atoms lossis cov tebchaw) rau tshuav nyiaj li cas qhov sib npaug rau Potassium + Oxygen gas.
Ib yam li ntawd, K o2 yog dab tsi?
K + O 2 → K O. 2 K yog ib tug txo tus neeg sawv cev, O 2 yog oxidizing tus neeg sawv cev. Reactants: K . Lub npe: Potassium, K , Element 19, Kalium. Cov tsos mob: Dawb-rau-grey lumps.
Qhov thib ob, koj ua li cas sib npaug sib npaug? Txoj Kev 1 Ua ib qho piv txwv
- Sau koj qhov kev sib npaug.
- Sau tus naj npawb ntawm atoms rau ib lub caij.
- Txuag hydrogen thiab oxygen rau qhov kawg, vim lawv feem ntau ntawm ob sab.
- Pib nrog ib lub ntsiab lus.
- Siv cov coefficient kom sib npaug ntawm ib qho carbon atom.
- Ntsuas cov hydrogen atoms tom ntej.
- Ntsuas cov pa oxygen atoms.
Kuj Paub, qhov sib npaug ntawm cov poov tshuaj thiab oxygen yog dab tsi?
Potassium oxide ( K2O ) lub Kalium oxide yog ib qho ionic compound ntawm poov tshuaj thiab oxygen. Cov khoom no daj ntseg daj, qhov yooj yim tshaj plaws oxide ntawm cov poov tshuaj, yog ib qho tsis tshua pom, muaj zog heev.
Cov tshuaj tiv thaiv dab tsi yog k2o h2o?
K2O + H2O → 2KOH Potassium oxide teb nrog dej los tsim cov poov tshuaj hydroxide.

Kuv yuav ntsuas kuv qhov nyiaj tshuav Sartorius li cas?
Txheeb xyuas qhov nyiaj tshuav yog qib, tom qab ntawd xoom qhov nyiaj tshuav los ntawm kev tsim nyog thiab ua qhov kev ntsuas sab hauv, hloov kho. Txhawm rau ua cov txheej txheem Kev Kho Hniav Sab Hauv, nias lub 'CAL' softkey, ces nias lub 'Start' softkey. USP hais tias qhov tsis paub meej yam tsawg kawg nkaus yuav tsum tsis pub ntau tshaj 0.1% ntawm qhov hnyav hnyav
Dab tsi yog qhov loj tshaj plaws ntawm triple beam tshuav nyiaj li cas?
610g ua Nyob rau hauv tas li ntawd, yog vim li cas yog ib tug triple beam tshuav nyiaj li cas los ntsuas huab hwm coj? Pawg yog tus nqi ntawm cov khoom uas muaj. Peb feem ntau siv a peb npaug - balance beam rau ntsuas qhov loj . A peb npaug - beam tshuav tau txais nws lub npe vim nws muaj peb kab teeb uas tso cai rau koj mus paub pawg nrog rau nqaj .
