A copper spoon had fallen into a container containing dil. HCl. What would happen to it in three days time?

Explanation

### Step-by-Step Solution

1. **Identify the Situation**: A copper spoon has fallen into a container of dilute hydrochloric acid (HCl).

2. **Understand Reactivity Series**: The reactivity series is a list that ranks metals based on their reactivity. In this series, metals like potassium and sodium are highly reactive, while metals like copper, silver, and gold are much less reactive.

3. **Locate Copper in the Reactivity Series**: Copper is positioned below hydrogen in the reactivity series, indicating that it is less reactive than hydrogen.
