\(\rightarrow\)19Zn+48HNO3\(\rightarrow\)19Zn(NO3)2+2NO+4N2O+24H2O

2N⁺⁵ +10e\(\rightarrow\)2N0 .2

2N⁺⁵+ 8e\(\rightarrow\)2N⁺¹ .1

\(\rightarrow\)6N+5 +28e\(\rightarrow\)4N0 +2N+1 .3

Al\(\rightarrow\)Al+3 +3e _________.28

\(\rightarrow\)28Al+102HNO3\(\rightarrow\)28Al(NO3)3+6N2+3N2O+51H2O

2Fe⁺² \(\rightarrow\)2Fe⁺³ +2e .5

Mn⁺⁷ +5e\(\rightarrow\)Mn⁺² .2

\(\rightarrow\)10FeSO4+2KMnO4+2KHSO4\(\rightarrow\)5Fe2(SO4)3+2MnSO4+2K2SO4+H2O

4. (5x-2y)AL + (18x-6y)HNO3 -------> (5x-2y)AL(NO3)3 + 3NxOy +(9x-3y)H2O

5. 2M + 2nH2SO4--------> M2(SO4)n + nSO2 + 2nH2O

6. (5x-2y)M + (6nx-2ny)HNO3 -------->(5x-2y) M(NO3)n +n NxOy + (3nx-ny)H2O

7. 11Zn + 28HNO3 -------> 11Zn( NO3)2 + 2NO + 2N2O + 14H2O

8. 46AL + 168HNO3 -------;> 46AL( NO3)3 + 9N2 + 6N2O + 84H2O

9. 10FeSO4 + 2KMnO4 + 16KHSO4 ---> 5Fe2(SO4)3 +9 K2SO4 + 2MnSO4 + 8H2O.

a)\(Fe+H_2SO_4loãng\rightarrow FeSO_4+H_2\)

b)\(CaO+H_2O\rightarrow Ca\left(OH\right)_2\)

c)\(\left(5x-2y\right)Al+\left(18x-6y\right)HNO_3\rightarrow\left(5x-2y\right)Al\left(NO_3\right)_3+3N_xO_y+\left(9x-3y\right)H_2O\)

Chúc em ngủ ngon.

a) \(H_2+FeSO_4\)

b) \(Ca\left(OH\right)_2\) 

c) \(NO_2\)

FeS\(_2\) + 8HNO\(_3\) ---> Fe(NO\(_3\))\(_3\) + 2H\(_2\)SO\(_4\) + 5NO+ 2H2O

FeS2 + 8HNO3 ➜ Fe(NO3)3 + 5NO + 2H2SO4 + 2H2O

\(PTHH:FeS_2+8HNO_3\rightarrow Fe\left(NO_3\right)_3+2H_2SO_4+5NO+2H_2O\)

1) FeS₂ + 5HNO₃ + 3HCl → FeCl₃ + 2H₂SO₄ + 5NO + 2H₂O (Câu 1 nên sửa Fe₂O₃ thành FeS₂ thì mới viết được phương trình)

2) (5x-2y)Fe + (18x-6y)HNO₃ → (5x-2y)Fe(NO₃)₃ + 3NxOy + (9x-3y)H₂O

3) 3FexOy + (12x-2y)HNO₃ → 3xFe(NO₃)₃ + (3x-2y)NO + (6x-y)H₂O

4) 2FexOy + (6x-2y)H₂SO₄ → xFe₂(SO₄)₃ + (3x-2y)SO₂+ (6x-2y)H₂O

5) 2CrI₃ + 64KOH + 27Cl₂ → 2K₂CrO₄ + 6KIO₄ + 54KCl + 32H₂O

bạn có bị nhầm k vậy? ở phản ứng đầu không có chât tham gia nào mang nguyên tố S cả thê nhưng sau phản ứng co axit sunfuric là sao vậy????

2) \(\left(5x-2y\right)Fe+\left(18-6y\right)HNO_3\rightarrow\left(5x-2y\right)Fe\left(NO_3\right)_3+3N_xO_y+\left(9x-3y\right)H_2O\)

FeS₂ + 8HNO₃ \(\rightarrow\) 2H₂SO₄ + Fe(NO₃)₃ + 5NO + 2H₂O

2KMnO₄ + 5SO₂ + 2H₂O \(\rightarrow\) K₂SO₄ + 2MnSO₄ + 2H₂SO₄

FeS2 + 8HNO3 → 2H2SO4 + Fe(NO3)3 + 5NO + 2H2O

FeS₂ + 8HNO₃ ===> 2H₂SO₄ + Fe(NO3)₃ + 5NO + 2H₂O

2KMnO₄ + 5SO₂ + 2H₂O ===> H₂SO₄ + 2MnSO₄ + 2H₂SO₄

Chúc bn học tốt!!!

a) → 

b) →

c) → 

d) → 

e) (5x−2y)Fe(NO₃)₃ + 3N_xO_y + (15x−3y/2)H₂O
