Dobrý deň,
Vedeli by ste mi prosím vysvetliť čo je adícia alkoholov a aldolová kondenzácia a popísať čo sa pri týchto reakciách deje na určitom príklade?
Ďakujem
Dobrý deň, vie mi niekto poradiť? Ďakujem. Vypočítajte, aká je koncentrácia [OH-] v roztoku, ak koncentrácia [H3O+] = 10-11 mol/dm3. Aké je pH daného roztoku?
Zdravim. Rád by son sa opytal, či platí zákon zachovania hmotnosti aj v skupenských premenách. Napr. ak máme 1kg vody a premení sa na vodnú paru, tak bude hmotnosť pary tiež 1kg? Vďaka za odpoveď.
