Group 8A - Lub Noble lossis Inert Gases. Pawg 8A (los yog VIIIA) ntawm lub sij hawm lub sij hawm yog cov noble gases los yog inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), thiab radon (Rn).
Vim li cas pab pawg 7 hu ua cov pa roj tsw qab?
Cov atoms ntawm noble gases twb muaj tag nrho cov plhaub sab nraud, yog li lawv tsis muaj kev nyiam poob, nce, lossis faib cov electrons. Qhov no yog vim li cas cov pa roj noble yog inert thiab tsis koom nrog tshuaj lom neeg. … atoms ntawm pab pawg 1 thiab 7 cov ntsiab lus muaj cov plhaub sab nrauv tsis tiav (yog li lawv rov ua dua)
Puas yog cov pa roj carbon monoxide 0 lossis 8?
About the Noble Gases
Pab 0 siv los hu ua Pab 8 tab sis qhov no ua rau muaj kev ntxhov siab vim tias feem ntau cov ntsiab lus hauv Pawg 8 muaj 8 electrons hauv lawv lub Plhaub sab nrauv tab sis Helium tsuas muaj 2, yog li nws tau hloov npe rau Pawg 0. Cov Noble Gases yog tag nrho cov inert uas txhais tau tias lawv tsis hnov mob nrog lwm cov atoms.
Puas yog pab pawg neeg muaj koob muaj npe 0?
Pab Pawg 0 muaj cov ntsiab lus tsis yog hlau tso rau hauv kab ntsug ntawm sab xis ntawm lub rooj zaum. Cov ntsiab lus hauv pawg 0 yog hu ua cov pa roj carbon monoxide. Lawv nyob ua ib lub atoms.
Pab 0 hu ua dab tsi?
Cov ntsiab lus hauv pab pawg 0 yog hu ua cov roj uas muaj txiaj ntsig. Lawv nyob ua ib lub atoms.

Los ntawm cov pa roj carbon monoxide ua rau muaj kuab paug?
Gases uas ua rau huab cua muaj kuab paug muaj xws li carbon, nitrogen thiab sulfur oxides. Txawm hais tias qee qhov ntawm cov pa roj no tshwm sim ib txwm muaj, zoo li carbon dioxide nyob rau hauv kev tshem tawm ntawm huab cua los ntawm lub ntsws, cov pa phem loj tuaj los ntawm kev hlawv cov fossil fuels:
Puas pab pawg pab pawg txhawb nqa pawg?
khoom plig stacks txhua lub sijhawm. Tam sim no, thaum koj qhib MyPlayer nav, nco ntsoov xyuas nrog koj cov xwm txheej. Feem ntau koj tsis tas yuav ua dab tsi kom tau txais koj VC los ntawm lawv, tab sis nws yuav pab tau rau hauv cov ntaub ntawv.
Vim li cas cov pa roj carbon monoxide tsis zoo rau ib puag ncig?
Ntxiv rau qhov cuam tshuam los ntawm cov hluav taws kub hnyiab, lawv yog txawm tias muaj kev phom sij ntau dua thaum lawv khiav hauv lawv daim ntawv tsis tau hlawv. Toxic, carcinogenic molecules muaj nyob rau hauv lub cav tso pa, nrog rau evaporating roj av thiab roj.
Cov pa roj carbon monoxide puas ua rau qaug dab peg?
Carbon monoxide (CO) lom yog ib qho xwm txheej kho mob hnyav tshaj plaws uas ua rau muaj kev phom sij rau lub neej, suav nrog cov hlab plawv thiab paj hlwb. Mob CO lom tuaj yeem ua rau myocardial ischemia, ventricular arrhythmia, syncope, qaug dab peg, thiab coma.
Cov chav sib cais nyob rau hauv pab pawg nyob qhov twg?
Tsim chav sib cais Pib lub rooj sib tham. Nyob hauv lub rooj sib tham tswj, xaiv chav Breakout. Ua raws li hauv qab no: Xaiv cov chav koj xav tau (50 max). Xaiv seb koj puas xav kom Pab Pawg sib npaug muab cov neeg mus rau chav (Tsis Siv Neeg) lossis muab cov neeg koj tus kheej (Manually).
