Ответ:
Объяснение:
C + O2 = CO2
2NaOH + CO2 = Na2CO3 + H2O
Na2CO3 + HCl = NaCl + H2CO3
--------
Fe(OH)2 =(t°) FeO + H2O
FeO + H2 = Fe + H2O
Fe + 2HCl = FeCl2 + H2
---------
S + O2 = SO2
H2O + SO2 = H2SO3
CaO + H2SO3 = CaSO3 + H2O
-----------
2Cu + O2 = 2CuO
CuO + 2HCl = CuCl2 + H2O
CuCl2 + 2NaOH = 2NaCl + Cu(OH)2 осадок
Сu(OH)2 =(t°) CuO + H2O
