Question

Cu➡️CuO➡️CuSo4➡️Cu(OH)2➡️CuO

Answer 1

Ответ:

Объяснение:

2Cu + O2 = 2CuO

CuO + H2SO4 = CuSO4 + H2O

CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4

Cu(OH)2 -> CuO + H2O

Answer 2

It looks like you've provided a sequence of chemical reactions involving copper (Cu) and some of its compounds. Let's break down the reactions step by step:

1. Copper to Copper Oxide (CuO):

   Copy code
   2 Cu + O2 → 2 CuO
   

   In this reaction, copper reacts with oxygen to form copper oxide.

2. Copper Oxide to Copper Sulfate (CuSO4):

   Copy code
   CuO + H2SO4 → CuSO4 + H2O
   

   Copper oxide reacts with sulfuric acid to produce copper sulfate and water.

3. Copper Sulfate to Copper Hydroxide (Cu(OH)2):

   scssCopy code
   CuSO4 + 2 NaOH → Cu(OH)2 + Na2SO4
   

   Copper sulfate reacts with sodium hydroxide to form copper hydroxide and sodium sulfate.

4. Copper Hydroxide to Copper Oxide (CuO): Copper hydroxide can undergo dehydration to form copper oxide, but the specific reaction conditions would determine the mechanism.

It's important to note that these reactions are simplified and might not capture all the details that could occur in a laboratory setting. Reaction conditions, stoichiometry, and other factors can influence the actual outcomes of these reactions. If you're performing these reactions in a laboratory setting, make sure to follow proper safety procedures and consult reliable sources for detailed instructions.
