It looks like you're asking about the reaction of copper(II) oxide (CuO) and zinc oxide (ZnO) with carbon (C), carbon monoxide (CO), and hydrogen (H2). Below are the expected chemical reactions for each case:

For Copper(II) Oxide (CuO):

1. CuO + C → Cu + CO

   • Copper(II) oxide is reduced by carbon to form copper and carbon monoxide.

2. CuO + CO → Cu + CO2

   • Copper(II) oxide can also react with carbon monoxide, reducing to copper while oxidizing CO to carbon dioxide.

3. CuO + H2 → Cu + H2O

   • Copper(II) oxide reacts with hydrogen, reducing to copper and producing water.

For Zinc Oxide (ZnO):

1. ZnO + C → Zn + CO

   • Zinc oxide is reduced by carbon to produce zinc and carbon monoxide.

2. ZnO + CO → Zn + CO2

   • Zinc oxide can also react with carbon monoxide, reducing to zinc and oxidizing CO to carbon dioxide.

3. ZnO + H2 → Zn + H2O

   • Zinc oxide reacts with hydrogen, producing zinc and water.

Summary

Both CuO and ZnO can undergo reduction reactions with carbon, carbon monoxide, and hydrogen to yield their respective metals along with different byproducts such as CO, CO2, or water, depending on the reducing agent used.
