К какому классу веществ относятся: CaO, H2S, NaCl, Ca3 (PO4) 2, N2O5, AgNO3, Mg, FeSO4, HNO3, K2SiO3, Na2O, H2SO4, K3PO4, PbS, P2O5, H2CO3, ZnSO4, Cu, H2SO3, ZnCl2, BaO, Ba, SO3, K3PO4, HNO3, CaS, Hg (NO3) 2, HgCl2, BaSO4, MgO, Na2SO4, CO2, CaSiO3,

Na+HCl = Mg+HCl = Al+HCl = Mg+H3PO4= Ca+H3PO4= Zn+H2SO4= Al+H2SO4= MgO+H2SO4= Zn+HCl = Cao+HCl = Fe2O3+HCl = Fe2O3+H2SO4= Li2O+H3PO4= MgO+H3PO4= Al2O3+H2SO4= Cu+HCl = Mg+H2SO4= NaCl+HCl = Na2So4+HCl = Fe (OH) 3+HNO3= Au+H2SO4= H3PO4+H2SO4=

CaCl2+Ca = Ca+CaO = CaCO3+CaO = CaCO3+CaSiO3 = CaO+CaSiO3 = CaO+Ca (OH) 2+CaSiO3 = Ca (OH) 2+Ca (NO3) 2 = Ca (OH) 2+CaCO3 = CaCO3+Ca (NO3) 2 = Ca (NO3) 2+O2 = CaCO3+Ca (HCO3) 2 = CaCO3+CaO = Ca (HCO#) 2+CaO=

Выберите окислительно-восстановительные реакции: 1. NH3+H2SO4=NH4HSO4 2. NH3+O2=NO+H2O 3. Ca (OH) 2+CO2=CaCO3+H2O 4. Na2O2=Na2O + O2 5. P2O5+HNO3=H3PO4+N2O5 6. Na2S2O3+H2SO4=Na2SO4+H2S 7. Na2S+H2SO4=NA2SO4+H2S 8. Na2S+Cl2=S+NaCl 9.
