Помогите решить :Fe(OH )3 + 3HNO3 Al2(SO4)3 +NaOH
Al+HBr AlO3+HCl
Fe3O4+H2 Cu2O+C ZnO+HNO2 Fe (OH) 3 + 3HNO3
Al2 (SO4) 3 + NaOH Al + HBr. AlO3 + HCl. Fe3O4 + H2. Cu2O + C ZnO + HNO2

Answer 1

Fe(OH)3 + 3HNO3 -> Fe(NO3)3 + 3H2O

Al2(SO4)3 + 6NaOH -> 2Al(OH)3⬇️ + 3Na2SO4

2Al + 6HBr -> 2AlBr3 + 3H2

Al2O3 + 6HCl -> 2AlCl3 + 3H2O

Fe3O4 + 4H2 -> 3Fe + 4H2O

Cu2O + C -> CO + 2Cu

ZnO + 2HNO2 -> Zn(NO2)2 + H2O
