Make up the equations of reactions to the chain of transformations: CuSO4 – Cu (OH) 2 – CuO – Cu – CUS – Cu (NO3) 2 – Cu

CuSO4 – Cu (OH) 2 – CuO – Cu – CUS – Cu (NO3) 2 – Cu is an example of a chain of transformations.
We compose the equations:
CuSO4 + 2NaOH = Cu (OH) 2 + Na2SO4 – ion exchange;
Cu (OH) 2 = CuO + H2O – decomposition:
CuO + H2 = Cu + H2O – reduction reaction, while copper is formed;
Cu + S = CuS – compounds;
CuS + 10HNO3 (conc.) = Cu (NO3) 2 + H2SO4 + 8NO2 + 4H2O – ОВР;
Cu (NO3) 2 + Zn = Cu + Zn (NO3) 2 – substitutions.
The equations show the genetic relationship of copper salts, hydroxide, oxide, a simple substance of copper metal.
