The book generally focuses on the quantitative relationships in chemical reactions and compounds, including:
While not an internationally famous author, "Šikirić" is a recognized name in regional secondary school and early university chemistry education. Materials attributed to Šikirić typically focus on practical, step‑by‑step stoichiometric calculations: mole ratios, limiting reagents, percent yield, empirical formulas, and gas stoichiometry. sikirica stehiometrija pdf
Izgaranje metana: CH4 + 2 O2 → CO2 + 2 H2O Ako imamo 16 g CH4 i suficijentno O2, molovi CH4 = 16/16 = 1 mol → daje 1 mol CO2 (44 g). The book generally focuses on the quantitative relationships
: Unlike standard textbooks that often skip the "obvious" steps, Sikirica's examples guide you through the logic of stoichiometry. : Unlike standard textbooks that often skip the
“Željezo se dobiva redukcijom željezova(III) oksida ugljikovim(II) oksidom prema jednadžbi: Fe2O3 + 3CO → 2Fe + 3CO2. Izračunaj masu željeza koja se može dobiti iz 160 kg željezova(III) oksida ako je iskorištenje reakcije 85%.”
