Question

Закончить уравнение возможных реакций в молекулярной и ионной форме:1)KOH+Fe(NO3)2,2)Ba(OH)2+CO2,3)Co(OH)2,4)Ni(OH)2+H2SO4,5)Zn(OH)2+HNO3,6)Al(OH3)7)NaOH+N2O3,8)Cr(OH)3+MgSO4

Answer 1

1. KOH+Fe(NO3)2 = Fe(OH)2 + KNO3

 2. Ba(OH)2+CO2 = BaCO3 + H20

5. Zn(NO3)2 + H2O

только что знаю)

Answer 2

1)KOH+Fe(NO3)2=2KNO3+Fe(OH)2

2)Ba(OH)2+CO2= BaCO3(осадок) + H2O

3)Co(OH)2= CoO + H2O (повышение температуры)

5)Zn(OH)2+HNO3= Zn(NO3)2 + 2H2O

6)Al(OH3)=Al2O3 + 3H2O (повышение температуры)

7)NaOH+N2O3= 2NaNO2 + H2O

8)Cr(OH)3+MgSO4-не реагирует

Answer 3

Equations in Molecular and Ionic Form:

1) KOH + Fe(NO3)2: - Molecular Equation: KOH + Fe(NO3)2 → KNO3 + Fe(OH)2 - Ionic Equation: 2KOH + Fe(NO3)2 → 2KNO3 + Fe(OH)2 2) Ba(OH)2 + CO2: - Molecular Equation: Ba(OH)2 + CO2 → BaCO3 + H2O - Ionic Equation: Ba2+ + 2OH- + CO2 → BaCO3 + 2H2O 3) Co(OH)2: - Co(OH)2 does not react with any specific compound mentioned in the question.

4) Ni(OH)2 + H2SO4: - Molecular Equation: Ni(OH)2 + H2SO4 → NiSO4 + 2H2O - Ionic Equation: Ni(OH)2 + H2SO4 → Ni2+ + SO4^2- + 2H2O 5) Zn(OH)2 + HNO3: - Molecular Equation: Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O - Ionic Equation: Zn(OH)2 + 2H+ + 2NO3- → Zn2+ + 2NO3- + 2H2O 6) Al(OH)3: - Al(OH)3 does not react with any specific compound mentioned in the question.

7) NaOH + N2O3: - NaOH + N2O3 does not form a stable compound or reaction.

8) Cr(OH)3 + MgSO4: - Molecular Equation: Cr(OH)3 + MgSO4 → Cr(SO4)3 + Mg(OH)2 - Ionic Equation: Cr(OH)3 + 3H2O + 3MgSO4 → Cr(SO4)3 + 3Mg(OH)2 [[1]](https://adu.by/images/2023/him/fz-himia-10kl-dlya-uchashichsa.pdf)

Please note that not all combinations mentioned in the question will result in a reaction or a stable compound.
