Answer 1

Ответ:

Объяснение:

A)

4Al + 3O2 = 2Al2O3

Al2O3 + 6HBr = 2AlBr3 + 3H2O

AlBr3 + 3NaOH = Al(OH)3 + 3NaBr

2Al(OH)3 =t= Al2O3 + 3H2O

Al2O3 + 3H2S = Al2S3 + 3H2O

Б)

ZnSO4 + 2NaOH = Zn(OH)2 + Na2SO4

Zn(OH)2 =t= ZnO + H2O

ZnO + 2HI = ZnI2 + H2O

B)

MgCl2 + H2SO4 = MgSO4 + 2HCl

MgSO4 + BaCl2 = MgCl2 + BaSO4

3MgCl2 + 2K3PO4 = Mg3(PO4)2 + 6KCl

Answer 2

A) AL → Al2O3 → AlBr3 → Al(OH)3 → Al2O3 → Al2(SO4)3

The given transformation starts with AL and goes through several steps to reach Al2(SO4)3. Let's break down each step:

1. AL → Al2O3: The first transformation is the oxidation of AL to form Al2O3, which is aluminum oxide. 2. Al2O3 → AlBr3: The second transformation involves the reaction of Al2O3 with bromine to form AlBr3, which is aluminum bromide. 3. AlBr3 → Al(OH)3: The third transformation is the reaction of AlBr3 with water to form Al(OH)3, which is aluminum hydroxide. 4. Al(OH)3 → Al2O3: The fourth transformation involves the dehydration of Al(OH)3 to form Al2O3, which is aluminum oxide. 5. Al2O3 → Al2(SO4)3: The final transformation is the reaction of Al2O3 with sulfuric acid to form Al2(SO4)3, which is aluminum sulfate.

B) ZnSO4 → Zn(OH)2 → ZnO → ZnI2

The given transformation starts with ZnSO4 and goes through several steps to reach ZnI2. Let's break down each step:

1. ZnSO4 → Zn(OH)2: The first transformation is the reaction of ZnSO4 with a base, such as sodium hydroxide, to form Zn(OH)2, which is zinc hydroxide. 2. Zn(OH)2 → ZnO: The second transformation involves the dehydration of Zn(OH)2 to form ZnO, which is zinc oxide. 3. ZnO → ZnI2: The final transformation is the reaction of ZnO with iodine to form ZnI2, which is zinc iodide.

В) MgCl2 → MgSO4 → MgCl2 → Mg3(PO4)2

The given transformation starts with MgCl2 and goes through several steps to reach Mg3(PO4)2. Let's break down each step:

1. MgCl2 → MgSO4: The first transformation is the reaction of MgCl2 with sulfuric acid to form MgSO4, which is magnesium sulfate. 2. MgSO4 → MgCl2: The second transformation involves the reaction of MgSO4 with hydrochloric acid to form MgCl2, which is magnesium chloride. 3. MgCl2 → Mg3(PO4)2: The final transformation is the reaction of MgCl2 with phosphoric acid to form Mg3(PO4)2, which is magnesium phosphate.
