Solution

The balanced equation for the reaction of hydrogen gas and copper oxide is written as:

\[\ce{H2_{(g)} + CuO_{(s)} -> Cu_{(s)} + H2O_{(g)}}\]

The chemicals are:

  1. Elements: Hydrogen (H2) and Copper (Cu)
  2. Compounds: Copper oxide (CuO) and Water (H2O)
  3. Reactants: Hydrogen (H2) and Copper oxide (CuO)
  4. Products: Copper (Cu) and Water (H2O)
  5. Metal: Copper (Cu)
  6. Non-metal: Hydrogen (H2)
