te dwa zadania
Zad. 8
A ─ CH3COOK, octan potasu
B ─ (CH3COO)3Al, octan glinu
C ─ (CH3COO)2Ba, octan baru
D ─ (CH3COO)2Pb, octan ołowiu (II)
1) 2CH3COOH + 2K → 2 CH3COOK + H2
2) CH3COOH + Al2O3 → 2(CH3COO)3Al + 3H2O
3) CH3COOH + Ba(OH)2→ (CH3COO)2Ba + 2H2O
4) CH3COOH + O2 → 2CO + 2H2O
5) 2CH3COOH + PbO → (CH3COO)2Pb + H2O
6) CH3COO- + H20 → CH3COOH + OH-
Zad. 9
A ─ O2, tlen
B ─ HCOOCH3, mrówczan metylu
C ─ H2O, woda, tlenek wodoru
D ─ HCOONa, mrówczan sodu
1) HCOOH + CH3OH → HCOOCH3 + H2O
2) 2Na + 2HCOOH → 2HCOONa + H2
3) 3O2 + 2CH3OH → 2CO2 + 4H2O
4) 2O2 + HCOOCH3 → 2CO2 + 2H2O
5) O2 + 2H2 → 2H2O
