Question

Cu-cuo-cucl2-cu(oh)2-cuo-cu(no3)2

Answer 1

Відповідь:

1) 2Cu+O₂→2CuO

2) CuO + 2HCl(разб.) → CuCl₂ + H₂O

3) Ca(OH)₂+CuCl₂→Cu(OH)₂+CaCl₂

4) 2HNO₃+Cu(OH)₂→Cu(NO₃)₂+2H₂O

5)Cu(NO₃)₂ + Na₂S → CuS + 2NaNO₃

Answer 2

It looks like you've listed a sequence of chemical reactions involving copper (Cu), copper(II) chloride (CuCl2), copper(II) hydroxide (Cu(OH)2), copper(II) oxide (CuO), and copper(II) nitrate (Cu(NO3)2). However, it's not clear if you're asking for an explanation of these reactions or if you have a specific question related to them. Could you please provide more context or specify what you'd like to know about these reactions?
