Помогите по химии! Уравнения.

1) Fe2O3=

2) CrCl3+HNO3=

3) Al2O3+HNO2=

4) Al+HCE=

5) Li2O+H3PO4=

6) Ba (No3) 2+H2SO4=

7) ZnCL2+ALBr3=

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=

к кислотам относится группа веществ: 1) а) H2S, K2S, HNO2 б) H2SO4, H2O, HCl в) H3PO4, H2SO4, H3PO4 г) NA2CO3, H2SO4, H3PO4 2) а) HNO2, H2O, H3PO4 б) K2CO3, H2CO3, CO2 в) H2SiO3, SiO2, HNO3 г) HNO2, HI, H3PO4

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=

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=

Закончите уравнение реакции, расставьте коэффициенты: HCE + Mg = HCE+K2CO3= HCE+Mg (OH) 2= HCE+BaO= HCE+KOH=
