K. Mikalajūnas Vaikai, kam jums tų atsakymų? Egzaminas baigėsi, o per egzaminą sukčiauti nepadoru. Palaukit, liepą sužinosit tikrus rezultatus, jau nieko nebepakeisit.

Katukas Atsakymai svarbūs tam, kad būtų pakankamai laiko apgalvoti tolimesnius studijų planus, todėl nemanau, kad tai yra sukčiavimas :)

Ne chemikas Pone Mikalajūnai, sukčiauti pasibaigus egzamino laikui neįmanoma, tiesiog įdomu sužinot rezultatus, kad būtų galima pamatyti bendrą vaizdą. Rezultatus egzamino savo sužinoti visi nori kuo greičiau, ir tame blogio nėra.

K Redaktoriau, paskatinkite, kad jie greičiau spręstų, mes mirštam iš smalsumo!

Žmogus Kaip 11 gali būti C, jei nei aromatiniai angliavandeniliai( stirenas, turintis benzeno žiedą) nei alkanai (heptanas) neblukina bromo vandens?
2024 birželio 13 d. 02:06   • 172.20.0.2
Žmogau, stirenas turi dvigubąjį ryšį, todėl blukina Br2 :)

Žmogus Ačiū, Aš, o tai su heptanu kaip tada?
2024 birželio 13 d. 02:06   • 172.20.0.2
Kadangi ten mišinys, tai turi bent vienas iš parašytų blukinti.

Žmogus Ačiū, supratau esmę- atidumo trūkumas.
