Answer 1

Ответ:

2HNO3 + ZnO → Zn(NO3)2 + H2O

FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4 (Реакция протекает в атмосфере азота.)

Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O (Обработка каолинита, боксита или алунита серной кислотой.)

CuCl2  + 2 KOH  → Cu(OH)2  + 2 KCl

Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O

2K3PO4 + 3Ba(NO3)2 → 6KNO3 + Ba3(PO4)2

2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O

3ZnO + 2H3PO4 (разб. р-р)→ Zn3(PO4)2 + 3H2O

3Zn + 2H3PO4 → Zn3(PO4)2+3H2↑

2Al(OH)3 → Al2O3 + 3H2O

Ba + 2H2O → Ba(OH)2 + H2

2Cs + 2H2O → 2CsOH + H2

Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation and balance them one by one.

1) ZnO + HNO3 → Zn(NO3)2 + H2O

To balance this equation, we need to ensure that the number of zinc (Zn), nitrogen (N), and oxygen (O) atoms is the same on both sides.

The balanced equation is: ZnO + 2HNO3 → Zn(NO3)2 + H2O [[1]].

2) FeSO4 + NaOH → Na2SO4 + Fe(OH)2

To balance this equation, we need to ensure that the number of iron (Fe), sulfur (S), oxygen (O), hydrogen (H), and sodium (Na) atoms is the same on both sides.

The balanced equation is: FeSO4 + 2NaOH → Na2SO4 + Fe(OH)2 [[2]].

3) Al2O3 + H2SO4 → Al2(SO4)3 + H2O

To balance this equation, we need to ensure that the number of aluminum (Al), oxygen (O), hydrogen (H), and sulfur (S) atoms is the same on both sides.

The balanced equation is: Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O [[3]].

4) CuCl2 + KOH → Cu(OH)2 + KCl

To balance this equation, we need to ensure that the number of copper (Cu), chlorine (Cl), oxygen (O), hydrogen (H), and potassium (K) atoms is the same on both sides.

The balanced equation is: CuCl2 + 2KOH → Cu(OH)2 + 2KCl [[4]].

5) Ba(OH)2 + HNO3 → Ba(NO3)2 + H2O

To balance this equation, we need to ensure that the number of barium (Ba), oxygen (O), hydrogen (H), nitrogen (N), and potassium (K) atoms is the same on both sides.

The balanced equation is: Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O [[5]].

6) K3PO4 + Ba(NO3)2 → KNO3 + Ba3(PO4)2

To balance this equation, we need to ensure that the number of potassium (K), phosphorus (P), oxygen (O), nitrogen (N), and barium (Ba) atoms is the same on both sides.

The balanced equation is: 2K3PO4 + 3Ba(NO3)2 → 6KNO3 + Ba3(PO4)2 [[6]].

7) Fe(OH)3 + H2SO4 → Fe2(SO4)3 + H2O

To balance this equation, we need to ensure that the number of iron (Fe), oxygen (O), hydrogen (H), and sulfur (S) atoms is the same on both sides.

The balanced equation is: 2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O [[7]].

8) ZnO + H3PO4 → Zn3(PO4)2 + H2O

To balance this equation, we need to ensure that the number of zinc (Zn), oxygen (O), hydrogen (H), and phosphorus (P) atoms is the same on both sides.

The balanced equation is: 3ZnO + 2H3PO4 → Zn3(PO4)2 + 3H2O [[8]].

9) Zn + H3PO4 → Zn3(PO4)2 + H2

To balance this equation, we need to ensure that the number of zinc (Zn), oxygen (O), hydrogen (H), and phosphorus (P) atoms is the same on both sides.

The balanced equation is: 3Zn + 2H3PO4 → Zn3(PO4)2 + 3H2 [[9]].

10) Al(OH)3 → Al2O3 + H2O

To balance this equation, we need to ensure that the number of aluminum (Al), oxygen (O), and hydrogen (H) atoms is the same on both sides.

The balanced equation is: 2Al(OH)3 → Al2O3 + 3H2O [[10]].

11) Ba + H2O → Ba(OH)2 + H2

To balance this equation, we need to ensure that the number of barium (Ba), oxygen (O), and hydrogen (H) atoms is the same on both sides.

The balanced equation is: Ba + 2H2O → Ba(OH)2 + H2 [[11]].

12) Cs + H2O → CsOH + H2

To balance this equation, we need to ensure that the number of cesium (Cs), oxygen (O), and hydrogen (H) atoms is the same on both sides.

The balanced equation is: 2Cs + 2H2O → 2CsOH + H2 [[12]].
