Question

ПОЖАЛУЙСТА ОЧЕНЬ НАДО решить уравнения реакций: 1.KNO3+Al(OH)3= 2.CaCO3+KOH= 3.Al2O3+NaOH= 4.Al2(SO4)3+NaOH

Answer 1

4. Al2(SO4)3+NaOH= Al(OH)3+Na2SO4
3. Al2O3+NaOH= 2NaAlO2+ H2O

Answer 2

1.3KNO3+Al(OH)3=3KOH+AL(NO3)3
2.CaCO3+2KOH=Ca(OH)2+K2CO3

Answer 3

1. KNO3 + Al(OH)3 = First, we need to determine the products of this reaction. KNO3 is a soluble salt and Al(OH)3 is a base. When a salt reacts with a base, it typically forms a metal hydroxide and a salt.

The balanced equation for this reaction is: 2 KNO3 + 3 Al(OH)3 = 3 KOH + Al(NO3)3

2. CaCO3 + KOH = In this reaction, CaCO3 is a solid and KOH is a strong base. When a strong base reacts with a solid carbonate, it typically forms a salt, water, and carbon dioxide gas.

The balanced equation for this reaction is: CaCO3 + 2 KOH = Ca(OH)2 + K2CO3

3. Al2O3 + NaOH = Al2O3 is a solid and NaOH is a strong base. When a strong base reacts with a metal oxide, it typically forms a salt and water.

The balanced equation for this reaction is: 2 Al2O3 + 6 NaOH = 2 Na3AlO3 + 3 H2O

4. Al2(SO4)3 + NaOH = Al2(SO4)3 is a salt and NaOH is a strong base. When a salt reacts with a strong base, it typically forms a metal hydroxide and a salt.

The balanced equation for this reaction is: Al2(SO4)3 + 6 NaOH = 2 Al(OH)3 + 3 Na2SO4
