Question

Помогите решить уравнения химической реакции:
HCl+Mg
HCl+CaO
HCl+NaOH
HCl+AgNO3
FeCl3+NaOH
Fe(OH)3+HCl
CuSO4+NaOH
CuSO4+Fe

Answer 1

1) 2HCl+Mg→MgCl2+H2
2) 2HCl+CaO→CaCl2+H2O
3) HCl+NaOH→NaCl+H2O
4) HCl+AgNO3→AgCl+HNO3
5) FeCL3+3NaOH→Fe(OH)3+3NaCl
6) Fe(OH)3+3HCl→FeCl3+3H2O
7) CuSO4+2NaOH→Na2SO4+Cu(OH)2
8) CuSO4+Fe→Cu+FeSO4

Answer 2

$2HCl+Mg=MgCl_2+H_2\\2HCl+CaO=CaCl_2+H_2O\\HCl+NaOH=NaCl+H_2O\\HCl+AgNO_3=AgCl+HNO_3\\FeCl_3+3NaOH=Fe(OH)_3+3NaCl\\Fe(OH)3+3HCl=FeCl_3+3H_2O\\CuSO_4+2NaOH=Na_2SO_4+Cu(OH)_2\\CuSO_4+Fe=Cu+FeSO_4$
