Нужно уровнять реакции - Mn2O7+H2 O=

BaO+HNO3=

MgO+HCl=

K2O+NaOH =

SiO2+Ba (OH) 2=

SO3+H2S=

SO3+CaO =, SO3+ZnO =, SO3+HNO3 =, SO3+Ca (OH) 2 =, SO3+CO2 =, SO3+NaOH =, SO3+MgO =, SO3+Cl2O3 =, SO3+H2O =.

Закончите уровнения: 1. Na2O + HCI; 2. K2O + H2S04; 3. Li2O + H3PO4; 4. CaO + HNO3; 5. CuO + HBr; 6. BaO + HNO3; 7. HgO + H2SO4; 8. MgO + HCI; 9. Li2O + HNO3; 10. CaO + HCI; 11. CO2 + NaOH; 12. SO2 + KOH; 13. SO3 + LiOH; 14. SiO2 + NaOH; 15.

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=

1. формулы только оксидов приведены в ряду 1) H2SO4, CaO, CuCl2 2) Na2CO3, Cl2O7 3) CO2, Li2O3, Al2O3 4) KOH, K2O, BaO 2. формулы только основных оксидов приведены в ряду 1) CO2, Al2O3, K2O 2) CaO, BaO, Na2O 3) NO2, MgO, SO2 4) P2O5, Fe2O3, ZnO 3.

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=
