The chemical reaction sequence you have written out starts with KClO3 and ends with CuSO4. Here is the breakdown of each step:

Decomposition of KClO3 (Potassium chlorate) into O2 (Oxygen gas)
2KClO3 --> 2KCl + 3O2

Combustion of O2 (Oxygen gas) to form H2O (Water)
O2 + 2H2 --> 2H2O

Decomposition of H2O (Water) into O2 (Oxygen gas) and H2 (Hydrogen gas)
2H2O --> 2H2 + O2

Reaction of O2 (Oxygen gas) with CaO (Calcium oxide) to form CuCl2 (Copper(II) chloride)
2CaO + 2CuO + 3O2 --> 2CuCl2

Reaction of CuCl2 (Copper(II) chloride) with CuO (Copper(II) oxide) to form Cu(OH)2 (Copper(II) hydroxide)
CuCl2 + CuO + 2H2O --> 2Cu(OH)2 + 2HCl

Reaction of Cu(OH)2 (Copper(II) hydroxide) with H2SO4 (Sulfuric acid) to form CuSO4 (Copper(II) sulfate)
Cu(OH)2 + H2SO4 --> CuSO4 + 2H2O

Overall, the chemical reaction sequence involves a series of decomposition, combustion, and replacement reactions to transform potassium chlorate into copper sulfate.
