Pekný sviatočný deň,
vedel by mi niekto poradiť, čo by bolo v tomto prípade lineárnej lomenej funkcie a,b,c, d ?
Keby tam bol len ten zlomok, je mi to jasné. Ale tým, že je pred zlomkom alebo za zlomkom nejaké číslo, tak ma to trošku zmiatlo.
Ďakujem za rady
Aký objem roztoku HNO,, w=68 %, so špecifickou hmotnost'ou 1,4 g.cm³ vstúpi do reakcie s fenolom za vzniku 22,9 g 2,4,6-trinitrofenolu (TNF)? M,(fenol)=94; M(TNF)=229; M (HNO,) = 63 Výsledky 19.85…
Dobrý deň, potrebujem pomôcť s úlohou č.2😇 Určte reakčné teplo reakcie: S(s) + 3/2 O2(g) →SO3(g) ∆H=? keď vieme: S(s) + O2(g) →SO2(g) ∆H=-296,5kJ/mol SO2(g) + 1/2 O2(g) →SO3(g) ∆H= -94,8kJ/mol
Poprosila by som o pomoc s výpočtom príkladov nakoľko robím niekde chybu a neviem prísť na to kde. Ďakujem za odpoveď.
