Give the reactions involved between carbon dioxide and metals.

Explanation

To understand the reactions involved between carbon dioxide (CO₂) and metals, we can break it down into a few key points. Here’s a step-by-step solution:

### Step 1: Understanding Carbon Dioxide
Carbon dioxide is a colorless gas that is produced by the combustion of carbon-containing materials and is also a byproduct of respiration in living organisms.

### Step 2: Reaction with Active Metals
When carbon dioxide reacts with active metals like sodium (Na) or calcium (Ca), they can form metal carbonates. For example:
- **Sodium + Carbon Dioxide:**
