Question

Химия: CuO + CuSO4 = CuO + NaOH = CuO + HCl = Fe + CuSO4 = Fe + NaOH = Fe + HCl = CaCO3 + CuSO4 = CaCO3+ NaOH = CaCO3 + HCl =

сашагалкина1 · Answer

Я думаю вы имели ввиду CuO + H2SO4, а не CuO + CuSO4, если нет то я не знаю как решить CuO + CuSO4 CuO + H2SO4 → CuSO4 + H2O CuO + 2NaOH → Cu(OH)2 + Na2OCuO + 2HCl → CuCl2 + H2OFe + 3CuSO4 → Fe(SO4)3 + 3Cu Fe + 2NaOH → Fe(NaOH)2Fe + 2HCl → FeCl2 + H2CaCO3 + CuSO4 → CuCO3 + CaSO4CaCO3 + 2NaOH → Na2CO3 + Ca(OH)2CaCO3 + 2HCl → H2O + CO2 + CaCl2...
