X: Cu(OH)₂

Y: CuO

Z: Cu

1) 2Cu(NO₃)₂\(\overset{t^0}{\rightarrow}\)2CuO+4NO₂+O₂

2) CuO+2HCl\(\rightarrow\)CuCl₂+H₂O

3) Cu(OH)₂+2HCl\(\rightarrow\)CuCl₂+2H₂O

4) Cu(OH)₂+2HNO₃\(\rightarrow\)Cu(NO₃)₂+2H₂O

5) Fe+CuCl₂\(\rightarrow\)FeCl₂+Cu

6) Cu+2AgNO₃\(\rightarrow\)Cu(NO₃)₂+2Ag

X\(\rightarrow\)Y\(\rightarrow\)Z: Cu(OH)₂\(\rightarrow\)CuO\(\rightarrow\)Cu

Cu(OH)₂\(\overset{t^0}{\rightarrow}\)CuO+H₂O

CuO+H₂\(\overset{t^0}{\rightarrow}\)Cu+H₂O
