Question

CuCl₂ + _ --> NaCl + _
Fe(NO₄)₃ + _ --> NaNO₃ + _
Fe(SO_{4)3 +} _ ---> FeCl₃ + _
FeCl₃ + _ --> Fe(NO₃)₃ + _
Na₂CO₃ + _ --> BaCO₃ + _
BaCO₃ + _ --> BaSO₄ + _

Answer 1

CuCl₂ + 2NaOH--> 2NaCl + Cu(OH)₂
3Fe(NO3)₃ +6 NaOH--> 6NaNO₃ +3 Fe(OH)2
Fe(SO₄)₃+3BaCl2 ---> 2FeCl₃ + 3BaSO₄
FeCl₃ +3 NaNO₃ --> Fe(NO₃)₃ + 3NaCl
Na₂CO₃ +Ba(OH)₂ --> BaCO₃ + 2NaOH
BaCO₃ + H₂SO₄ --> BaSO₄ +H₂O+CO₂

Answer 2

\(CuCl_2+2NaOH\rightarrow Cu\left(OH\right)_2\downarrow+2NaCl\\ Fe\left(NO_3\right)_3+3NaOH\rightarrow Fe\left(OH\right)_3\downarrow+3NaNO_3\\ Fe_2\left(SO_4\right)_3+3BaCl_2\rightarrow2FeCl_3+3BaSO_4\downarrow\\ FeCl_3+3AgNO_3\rightarrow Fe\left(NO_3\right)_3+3AgCl\downarrow\\ Na_2CO_3+Ba\left(NO_3\right)_2\rightarrow BaCO_3\downarrow+2NaNO_3\\ BaCO_3+H_2SO_4\rightarrow BaSO_4\downarrow+CO_2\uparrow+H_2O\)
