NH4NO2 = N2 + 2H2ON2 + 3H2 = 2NH34NH3 + 5O2 = 4NO + 6H2ONO + O3 = NO2 + O22NO2 + H2 = HNO2 + HNO3CuO + 2HNO3 = Cu(NO3)2 + H2O2Cu(NO3)2 = 2CuO + 4NO2 + O2CuO + H2 = Cu + H2OCuSO4 + H2 = Cu↓ + H2SO42H2SO4 + Cu = CuSO4 + SO2↑ + 2H2OCuSO4 + 2NaOH = Cu(OH)2↓ + Na2SO4Cu(OH)2 = CuO + H2OCuO + 2HNO3 = Cu(NO3)2 + H2OCu(NO3)2 + 2KOH = Cu(OH)2↓ + 2KNO32KNO3 = 2KNO2 + O24P + 5O2 = 2P2O5...
