Chemical Substances: Chem-Quiz

Ingabe Uyayazi Ifomula Ye-Amonia? Noma i-hydrogen peroxide? Siyini Isakhiwo SeBenzene? Funda izinto zamakhemikhali ezingaphezu kuka-300 ezifundwa emakilasini ezethulo nezithuthukisiwe zamakhemikhali.
Kunamazinga amane amakhulu:
1. I-Inorganic Chemistry: izinhlanganisela zezinsimbi (njenge-lithium hydride LiH) nezingezona izinsimbi (i-carbon dioxide CO2); i-inorganic acids (isibonelo, i-sulfuric acid H2SO4), usawoti (kuhlanganise nosawoti ovamile - i-sodium chloride NaCl), nama-polyatomic ions.
2. I-Organic Chemistry: Ama-Hydrocarbons (kusuka ku-methane kuya ku-naphthalene) nama-carboxylic acid (kusuka ku-formic kuya ku-benzoic acid). Imikhiqizo yemvelo, okuhlanganisa ama-amino acid angu-20 avamile nezisekelo ze-nucleic eziyingxenye ye-RNA nama-molecule e-DNA. Ungakwazi futhi ukufunda amaqembu abaluleke kakhulu asebenzayo kanye namakilasi wezinto eziphilayo.
3. Wonke ama-elementi amakhemikhali ayi-118 kanye nethebula le-periodic table: imibuzo ihlukaniswe Izinkathi 1–7.
4. Izinhlanganisela ezihlanganisiwe:
* Amagama ahlelekile namancane;
* izakhiwo namafomula;
* i-organic, inorganic, kanye ne-organometallic compounds;
* ukusuka kuma-acids nama-oxide kuya kuma-hydrocarbon notshwala;
* Amazinga amabili: 100 alula futhi 100 amakhemikhali anzima.

Khetha imodi yomdlalo:
1) Imibuzo yesipelingi (ilula futhi inzima) - qagela igama elithi uhlamvu ngohlamvu.
2) Imibuzo yokukhetha okuningi (enezimpendulo ezi-4 noma ezi-6). Kubalulekile ukukhumbula ukuthi unezimpilo ezi-3 kuphela.
3) Umdlalo wesikhathi (nikeza izimpendulo eziningi ngangokunokwenzeka ngomzuzu ongu-1) - kufanele unikeze izimpendulo ezifanele ezingaphezu kwama-25 ukuze uthole inkanyezi.
Amathuluzi okufunda amabili:
* Ama-flashcards lapho ungaphequlula khona wonke ama-compounds namafomula awo ngaphandle kokuqagela.
* Ithebula lazo zonke izinto ezikuhlelo lokusebenza.

Uhlelo lokusebenza lihunyushelwa ezilimini eziyi-12, okuhlanganisa isiNgisi, isiJalimane, iSpanishi, nezinye eziningi. Ngakho ungafunda amagama compounds amakhemikhali ngezilimi zakwamanye amazwe.
Izikhangiso zingasuswa ngokuthenga ngaphakathi nohlelo.

Iwuhlelo lokusebenza oluphelele lwawo wonke umfundi olungiselela imibuzo yekhemistri, izivivinyo, nama-olympiad amakhemikhali.
