KNO + H₂O D) Ba(OH)2, + H2SO_ E) ...... + MgSO4 F) Cr(OH)3 + 3НСІ -> + Н2О G) ..................... → AICI + H2O 2. Составьте уравнения реакций соляной и серной кислоты со следующими основаниями: Cu(OH)2, Al(OH)3, Fe(OH)3. люди добрые помогите срочно нужно..даю 50 баллов ​

Answer 1

Ответ:

A) H2SO4 + Zn -> ZnSO4 + H2↑

B) Al(OH)3 + 3HNO3 -> Al(NO3)3 + 3H2O

C) KNO + H2O -> KOH + HNO3

D) Ba(OH)2 + H2SO4 -> BaSO4↓ + 2H2O

E) Na2SO4 + MgCl2 -> MgSO4↓ + 2NaCl

F) Cr(OH)3 + 3НСІ -> CrCl3↓ + 3H2O

G) AlCl3 + 3H2O -> Al(OH)3↓ + 3HCl

Составление уравнений реакций соляной и серной кислоты со следующими основаниями:

1. Cu(OH)2 + 2HCl → CuCl2 + 2H2O

2. Al(OH)3 + 3HCl → AlCl3 + 3H2O

3. Fe(OH)3 + 3HCl → FeCl3 + 3H2O

Answer 2

A) Zn + 2HCl -> ZnCl2 + H2O

This is a single replacement reaction, also known as a displacement reaction. Zinc (Zn) displaces hydrogen (H) from hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and water (H2O). [[1]]

B) Al(OH)3 + 3HNO3 -> Al(NO3)3 + 3H2O

This is a double replacement reaction, also known as a metathesis reaction. Aluminum hydroxide (Al(OH)3) reacts with nitric acid (HNO3) to form aluminum nitrate (Al(NO3)3) and water (H2O). [[2]]

C) KNO3 + H2O -> KNO2 + HNO3

This is a decomposition reaction. Potassium nitrate (KNO3) decomposes into potassium nitrite (KNO2) and nitric acid (HNO3) when heated. [[3]]

D) Ba(OH)2 + H2SO4 -> BaSO4 + 2H2O

This is a double replacement reaction. Barium hydroxide (Ba(OH)2) reacts with sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and water (H2O). [[4]]

E) Mg + H2SO4 -> MgSO4 + H2

This is a single replacement reaction. Magnesium (Mg) displaces hydrogen (H) from sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4) and hydrogen gas (H2). [[5]]

F) Cr(OH)3 + 3HCl -> CrCl3 + 3H2O

This is a double replacement reaction. Chromium hydroxide (Cr(OH)3) reacts with hydrochloric acid (HCl) to form chromium chloride (CrCl3) and water (H2O). [[6]]

G) AlCl3 + 3H2O -> Al(OH)3 + 3HCl

This is a double replacement reaction. Aluminum chloride (AlCl3) reacts with water (H2O) to form aluminum hydroxide (Al(OH)3) and hydrochloric acid (HCl). [[7]]

Reactions of hydrochloric acid (HCl) and sulfuric acid (H2SO4) with copper hydroxide (Cu(OH)2), aluminum hydroxide (Al(OH)3), and iron hydroxide (Fe(OH)3):

1. HCl + Cu(OH)2 -> CuCl2 + 2H2O This is a double replacement reaction. Hydrochloric acid (HCl) reacts with copper hydroxide (Cu(OH)2) to form copper chloride (CuCl2) and water (H2O). [[8]]

2. HCl + Al(OH)3 -> AlCl3 + 3H2O This is a double replacement reaction. Hydrochloric acid (HCl) reacts with aluminum hydroxide (Al(OH)3) to form aluminum chloride (AlCl3) and water (H2O). [[9]]

3. H2SO4 + Fe(OH)3 -> Fe2(SO4)3 + 3H2O This is a double replacement reaction. Sulfuric acid (H2SO4) reacts with iron hydroxide (Fe(OH)3) to form iron(III) sulfate (Fe2(SO4)3) and water (H2O). [[10]]
