Huu hapa ni utatuzi wa maswali yako: i) Jina: (I) Gesi P: Carbon monoxide* (CO) (II) Kimiminika R: Asidi ya sulfuriki* (H_2SO_4) (III) Mabaki S: Uchafu usioyeyuka* (Insoluble impurities) ii) Jukumu la coke katika mchakato huu ni kama wakala wa kupunguza (reducing agent). Huondoa oksijeni kutoka kwa zinki oksidi (ZnO) na kuibadilisha kuwa zinki (Zn). iii) Uchafu mkuu unaoondolewa katika chumba cha kutenganisha ni chuma (iron) au risasi (lead). iv) Andika mlinganyo wa mmenyuko unaotokea katika: (I) Tanuru ya kuchoma (Roaster): 2ZnS_(s) + 3O_2(g) → 2ZnO_(s) + 2SO_2(g) (II) Chumba cha Mmenyuko II (Reaction Chamber II): ZnO_(s) + C_(s) → Zn_(g) + CO_(g) v) Andika mlinganyo wa mmenyuko unaotokea kati ya chuma cha zinki na kimiminika R: Zn_(s) + H_2SO_4(aq) → ZnSO_4(aq) + H_2(g) vi) Kuhesabu wingi wa zinki sulfidi: Step 1: Pata wingi wa zinki sulfidi katika madini. Wingi wa zinki sulfidi = 45\% × 250 kg Wingi wa zinki sulfidi = 0.45 × 250 kg = 112.5 kg Step 2: Badilisha wingi kuwa gramu. Wingi wa zinki sulfidi = 112.5 kg × 1000 g/kg = 112500 g vii) Matumizi moja ya kibiashara ya chuma cha zinki ni: • Kutengeneza aloi kama vile shaba (brass). • Kufanya galvanizing (kufunika chuma na zinki ili kuzuia kutu). 3 done, 2 left today.
