Tsis yog ib txwm kawm tus kheej pab kom nkag siab cov ntsiab lus, qee zaum koj xav tau kev pab los ntawm tus kws tshaj lij. Txhua tus kws qhia ntawv yuav teb cov lus nug ntawm yuav ua li cas yog tias koj tsis nkag siab txog chemistry. Tau kawg, koj yuav tsum hu rau tus kws qhia ntawv thiab mus kawm ntxiv.
Kev qhia
Kev kawm tus kheej yog qhov zoo yog tias koj muaj sijhawm txaus. Kev qhia ntawv yog tsim nyog rau koj yog tias:
- koj tsis xav ua lub luag haujlwm rau kev ua tau zoo ntawm cov txheej txheem uas kojkawm;
- koj paub tias koj yuam tsis tau koj tus kheej los kawm; koj them rau cov chav kawm, uas txhais tau tias koj tsis xav poob nyiaj;
- koj xav kom lwm tus tswj hwm koj qib kev paub.
Tau kawg, chav kawm nrog tus kws qhia ntawv muaj txiaj ntsig zoo dua li cov neeg ywj pheej. Feem ntau, lawv ua rau muaj kev txawj ntse tiag tiag. Peb tau txiav txim siab cov lus nug ntawm yuav ua li cas nkag siab txog chemistry. Tab sis ua li cas yog tias koj tsis xav kawm qhov kev tshawb fawb no?
Yuav ua li cas to taub chemistry: koj nyiam cov kev kawm yooj yim kawm
Yog tias chemistry dhau los ua qhov koj nyiam, cov lus nug ntawm yuav ua li cas nkag siab nws yuav raug daws los ntawm nws tus kheej. Nov yog qee txoj hauv kev los hloov txoj kev kawm ntawm qhov kev tshawb fawb no rau hauv kev nyiam:

- Muab khoom plig me me rau koj qhov kev ua tiav.
- Tsis txhob zaum los kawm yog tias koj lub siab nyob rau lwm yam. Chemistry yuav tsum tau ua kom pom tseeb thiab saib xyuas.
Zoo tias tsis muaj dab tsi nyuaj hauv cov lus qhia no, tab sis cov menyuam kawm ntawv tseem muaj qee yam tsis nyiam chemistry.
Vim li cas cov tub ntxhais kawm tsis nyiam chemistry
Tsuas yog cov neeg uas tsis nyiam txoj kev kawm no tsuas yog xav nkag siab txog chemistry. Qhov no tuaj yeem tshwm sim rau cov laj thawj hauv qab no:
- poob siab vim yog cov khoom siv theoretical ntau;
- yuav tsum nkim sijhawm;
- tus kws qhia ntawv yuav tsum tau ua haujlwm ntev ntev.
Cov teeb meem no cuam tshuam cov niam txiv, tsis yog menyuam yaus. Sim piav qhia rau koj tus menyuam tias kev vam meej hauv cheeb tsam no yuav tsum tau siv zog thiab ua siab ntev. Ces lo lus nug ntawm yuav ua li cas to taub chemistry yuav tsis tshwm sim.
Yuav ua li cas kom nkag siab txog cov organic chemistry
Kev kawm txog organic chemistry pib hauv high school. Yuav kom nkag siab txog cov ntsiab lus ntawm kev tshawb fawb, koj yuav tsum siv cov lus qhia saum toj no. Organic chemistry yog raws li inorganic chemistry, ntawm nws cov ntsiab lus thiab cov qauv. Yog li ntawd, koj yuav tsum pib kawm los ntawm lub hauv paus. Yog tias thawj zaug koj tsis muaj teeb meem, ces cov organic teeb meem kuj yuav succumb rau koj yooj yim. Tsis txhob tso tseg kev kawm nyob deb, ces koj yuav ua tiav.
