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

Explanation

To solve the question, we need to follow these steps:

### Step 1: Write the unbalanced chemical equation
When hydrogen gas (H₂) is passed over copper oxide (CuO), copper (Cu) and steam (H₂O) are produced. The unbalanced equation can be written as:
\[ \text{CuO} + \text{H}_2 \rightarrow \text{Cu} + \text{H}_2\text{O} \]

### Step 2: Balance the chemical equation
Now, we need to balance the equation. We have:
