Question

Закончите уравнение реакций.Составьте для них полные и сокращенные ионные уравненияFe(OH)3+H2SO4=>Mg(NO3)2+KOH=>K2CO3+BaCl2=>BaCO3+HCl=>

Answer 1

1) 2Fe(OH)3+3H2SO4=Fe2(SO4)3+3H2O
2)Mg(NO3)2+2KOH=Mg(OH)2+2KNO3
3)K2CO3+BaCl2=2KCl+BaCO3
4)BaCO3+2HCl=BaCl2+CO2+H2O 

Answer 2

Fe(OH)3 + H2SO4 = Mg(NO3)2 + KOH = K2CO3 + BaCl2 = BaCO3 + HCl

Fe(OH)3 + H2SO4 = Fe2(SO4)3 + H2O

The balanced equation for the reaction between Fe(OH)3 and H2SO4 is:

Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 3H2O [[1]]

Mg(NO3)2 + 2KOH = Mg(OH)2 + 2KNO3

The balanced equation for the reaction between Mg(NO3)2 and KOH is:

Mg(NO3)2 + 2KOH → Mg(OH)2 + 2KNO3 [[2]]

K2CO3 + BaCl2 = 2KCl + BaCO3

The balanced equation for the reaction between K2CO3 and BaCl2 is:

K2CO3 + BaCl2 → 2KCl + BaCO3 [[3]]

BaCO3 + 2HCl = BaCl2 + H2O + CO2

The balanced equation for the reaction between BaCO3 and HCl is:

BaCO3 + 2HCl → BaCl2 + H2O + CO2 [[4]]

Please note that the above equations are balanced and represent the complete ionic equations for the given reactions.
