Zinc liberates hydrogen gas when reacted with dilute hydrochloric acid, whereas copper does not. Explain, why?

Explanation

To explain why zinc liberates hydrogen gas when reacted with dilute hydrochloric acid, while copper does not, we can follow these steps:

### Step 1: Understand the Reactivity Series
The reactivity series is a list of metals arranged in order of decreasing reactivity. In this series, metals that are higher can displace those that are lower from their compounds.

### Step 2: Identify the Position of Zinc and Copper
In the reactivity series:
- Zinc (Zn) is positioned above hydrogen (H).
