Question

Осуществите превращения пожалуйста!! Даю 15 баллов! Cu - CuO - Cu(OH)2 - CuO - CuSO4

Answer 1

1.2Cu+O2->2CuO
2.СuO+2HCl=CuCl2+H2O
CuCl2+2KOH=2KCl+Cu(OH)2(реакция оксида меди(II) с водой невозможна)
3.Cu(OH)2->t CuO+H2O
4.CuO+H2SO4->CuSO4+H2O

Answer 2

Chemical Transformations of Copper (Cu)

Copper (Cu) undergoes various chemical transformations under different conditions. Let's explore the transformations you've mentioned.

Cu - CuO - Cu(OH)2 - CuO - CuSO4

1. Cu to CuO: - When copper (Cu) is exposed to oxygen, it undergoes a transformation to form copper oxide (CuO). - This can be represented by the chemical equation: `2Cu + O2 → 2CuO`.

2. CuO to Cu(OH)2: - Copper oxide (CuO) can react with water to form copper hydroxide (Cu(OH)2). - The chemical equation for this reaction is: `CuO + H2O → Cu(OH)2`.

3. Cu(OH)2 to CuO: - Copper hydroxide (Cu(OH)2) can decompose to form copper oxide (CuO) under certain conditions. - The decomposition reaction can be represented as: `Cu(OH)2 → CuO + H2O`.

4. CuO to CuSO4: - Copper oxide (CuO) can react with sulfuric acid (H2SO4) to form copper sulfate (CuSO4). - The chemical equation for this reaction is: `CuO + H2SO4 → CuSO4 + H2O`[[3]](https://mspak.herzen.spb.ru/wp-content/uploads/2015/06/uch_tmo.pdf).

These transformations demonstrate the versatility of copper in forming different compounds under specific chemical conditions.
