Помогите решить: а) K2CO3+HNO3

б) Mg+HCl

в) Cu+H2SO4

г) CuO+H2SO4

д) HNO3+CO2

е) Na2SO4+HCl

ж) Ba (OH) 2+H3PO4

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=

HBr+Mg= H2SO3+Pt= HNO3+Al= H2S+Na= H2SO4+Ba= H3PO4+Fe= H2SO3+Zn= HCl+Al= H3PO4+Al= HBr+Rb= HNO3+Zn= HF+Zn= H2SO4+Cs= H2SiO3+Cu= HCl+Zn= H2S+Ba= HBr+Cs= HNO3+Cu= H2S+K= H2SO4+Pt= H2SO3+Ba= H3PO4+Na= H2SO3+Rb= H2SO4+Li= HBr+Pb= HNO3+Co= HI+Zn=

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.

Fe2O3+H2SO4= Li2O+H3PO4= MgO+H3PO4= Al2O3+H2SO4= Cu+HCl = Mg+H2SO4= NaCl+HCl = Na2So4+HCl = Fe (OH) 3+HNO3= Au+H2SO4= H3PO4+H2SO4= Na2Co3+HCl= NaCl+HNO3=

Na + HCl = Al + HCl = Ca + H3PO4 = MgO + H3PO4 = Zn + HCl = Mg + H2SO4 = Fe (OH) 3 + HCl = CaO + HCl = Fe2O3 + H2SO4 = MgO + H3PO4 = Cu + HCl = H3PO4 + H2SO4 NaCl + HNO3
