Question

Cu-> CuO-> CuCl2-> Cu(OH)2-> CuO-> CuSO4-> Cu(OH)2-> H2O->NaOH-> Na3PO4​

Answer 1

Ответ:

Объяснение:

2Сu + O₂ = 2CuO

CuO + 2HCl = CuCl₂ + H₂O

CuCl₂ + 2NaOH = Cu(OH)₂ + 2NaCl

Cu(OH)₂ = (t) =CuO + H₂O

CuO + H₂SO₄ = CuSO₄ + H₂O

CuSO4 + 2KOH = Cu(OH)₂ + K₂SO4

Cu(OH)₂ = CuO + H₂O

Na₂O + H₂O = 2NaOH

3NaOH + H₃PO₄ = Na₃PO₄ + 3H₂O

Answer 2

It seems like you've provided a sequence of chemical reactions involving copper (Cu) and various compounds. Let me explain each step in this sequence:

1. Cu -> Copper metal (Cu): This is the symbol for elemental copper, which is a shiny, reddish-brown metal.

2. Cu -> CuO: This represents the oxidation of copper to form copper(II) oxide (CuO), which is a black or brownish-black solid.

3. CuO -> CuCl2: This may indicate the reaction of copper(II) oxide (CuO) with hydrochloric acid (HCl) to form copper(II) chloride (CuCl2), which is a greenish-blue solid.

4. CuCl2 -> Cu(OH)2: This might represent the reaction of copper(II) chloride (CuCl2) with sodium hydroxide (NaOH) to form copper(II) hydroxide (Cu(OH)2), which is a pale blue solid.

5. Cu(OH)2 -> CuO: This suggests that copper(II) hydroxide (Cu(OH)2) is dehydrated to form copper(II) oxide (CuO) again.

6. CuO -> CuSO4: This could indicate the reaction of copper(II) oxide (CuO) with sulfuric acid (H2SO4) to form copper(II) sulfate (CuSO4), which is a blue crystalline solid.

7. CuSO4 -> Cu(OH)2: This may represent the reaction of copper(II) sulfate (CuSO4) with sodium hydroxide (NaOH) to form copper(II) hydroxide (Cu(OH)2) again.

8. Cu(OH)2 -> H2O: This step suggests that copper(II) hydroxide (Cu(OH)2) can be dehydrated to form water (H2O).

9. H2O -> NaOH: This indicates the addition of sodium hydroxide (NaOH) to water (H2O). Sodium hydroxide is a strong base and is often dissolved in water.

10. NaOH -> Na3PO4: This suggests the reaction of sodium hydroxide (NaOH) with phosphoric acid (H3PO4) to form sodium phosphate (Na3PO4).

So, in summary, your sequence represents a series of chemical reactions involving copper and various compounds, including oxide, chloride, hydroxide, sulfate, water, sodium hydroxide, and sodium phosphate. These reactions can occur under specific conditions in a laboratory or industrial setting. If you have any specific questions about these reactions or need more information about a particular step, please feel free to ask.
