Question

When hydrogen is passed over copper oxide, copper and steam are formed. Write a balanced equation for this reaction and state which of the chemicals are:

1. elements
2. compounds
3. reactants
4. products
5. metal
6. non-metal

Answer 1

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)
